Dental X-rays in North Richland Hills
Here at Cornerstone Animal Hospital, we are proud to be able to offer our clients dental radiology.
It is our goal to stay on top of all medical advances, especially in veterinary medicine. Our veterinarians and staff are constantly learning so our hospital can be at the top of the game.
One way we do this is by offering digital dental radiographs. Taking radiographs during dental procedures allows veterinarians to correctly diagnose dental problems. It allows us to look inside your pet’s teeth and see their oral cavities. Digital dental radiographs allow us to decide which teeth need to be pulled and which are healthy enough to stay. They also help us decide if owners need to do more for their pets at home.
Digital radiographs are very safe and effective. We will be able to view the radiographs just seconds after they are taken, so they are an invaluable diagnostic tool during dental cleanings.
If you have any questions about digital dental radiology, don’t hesitate to contact us today at Cornerstone Animal Hospital.
Laser Therapy

We’re excited to announce that we now offer laser therapy—a cutting-edge treatment for pain and inflammation in pets. This therapy uses targeted wavelengths of light to promote faster healing, reduce pain, boost circulation, and lessen swelling. Numerous studies have shown that laser therapy can effectively address issues such as arthritis, joint pain, ligament sprains, muscle strains, dog and cat bites, feline acne and asthma, hotspots, post-surgery or trauma pain, hip dysplasia, lick granulomas, and snake or insect bites.
Many of our patients have already experienced the benefits of laser therapy with great success. If you think your pet could benefit or want to learn more, please give our office a call today at (817) 514-8387.

Grooming & Bathing in North Richland Hills
Cat and Dog Grooming in North Richland Hills
Grooming
Regular grooming is essential not only for your pet’s appearance but also for their overall health. Grooming helps reveal many health issues related to your pet’s hair, skin, paws, ears, eyes, and nails. Often, owners might overlook subtle changes or assume them to be normal. Fleas, ticks, and other external parasites are frequently detected during grooming, and timely treatment is crucial to prevent bigger problems.
At Cornerstone Animal Hospital, our experienced professional groomer offers a full range of grooming services for dogs and cats, including regular baths, medicated shampoo baths, breed-specific grooming and trims, shave-downs, de-shedding, and brush-outs. We ensure your pet looks and feels their best every visit. If you have special grooming requests, our groomer is happy to accommodate your preferences.
Our grooming salon provides personalized care to keep your pets healthy, clean, and smelling great. Feel free to contact our staff to discuss your pet’s needs, and we’ll tailor the services in consultation with the groomer.
The grooming salon at Cornerstone Animal Hospital is staffed by a certified and compassionate pet stylist. Our stylists treat dogs and cats gently and with care, ensuring your pet looks and feels wonderful after every appointment.
Our pet stylists are available every day except Thursdays and Sundays to meet your pet’s grooming and bathing needs. For appointment details, scheduling, and grooming options, please call us at (817) 514-8387. If your pet is boarding with us and needs grooming before going home, kindly inform us in advance.
Bathing
Regular baths keep your pet’s skin and coat clean, prevent odors, and promote a healthy, shiny coat. Pets with skin issues may benefit from medicated or specialty shampoo baths and conditioners.
Oral Hygiene
Regular teeth brushing slows plaque buildup, maintains healthy gums, and reduces bad breath. While brushing at home can be challenging, our grooming staff can efficiently perform this during grooming or bathing. For a thorough oral health exam or dental diagnostics, please schedule a visit with our veterinarian.
Vaccinations Required for Grooming Service
To ensure the safety of all pets and staff, Cornerstone Animal Hospital requires that pets using our grooming and bathing services be current on all core vaccinations.

Heartworm Care in North Richland Hills
What is Heartworm Disease?
Heartworm disease is a serious illness affecting dogs, cats, and ferrets. It is caused by a parasitic nematode (roundworm) commonly known as the heartworm. This disease is preventable with regular administration of a heartworm prophylaxis (preventative medication), as recommended by a veterinarian. At Cornerstone Animal Hospital, we offer a wide range of affordable heartworm prevention options for your pet.
Request an AppointmentClick here to watch a Video on Heartworm Disease
Where is it prevalent?
For heartworm prevalence in the USA, please visit The Heartworm Society.
Is it preventable?
Heartworm disease can be prevented by administering heartworm prophylaxis medication as advised by your veterinarian.
At Cornerstone Animal Hospital, we offer many affordable options. Be sure to check out our great promotions on heartworm medications.
Symptoms
Dogs with mild heartworm infection often show no symptoms or may have only a mild occasional cough. Moderate cases typically show coughing and exercise intolerance. Severe infections can cause anemia, fainting, and right-sided chronic heart failure.
Diagnosis
The simplest way to diagnose heartworm infection is through a heartworm test at your veterinarian’s office. At Cornerstone Animal Hospital, the test takes less than fifteen minutes. Dogs six months or older should test negative before starting prevention. Even puppies started on prevention early should be tested at six months. It takes about six months for heartworms to mature and be detectable by testing.
If heartworm is suspected, additional diagnostics like electrocardiograms, X-rays, and urine analysis may be performed.
Infection
Heartworms are transmitted by mosquitoes carrying infective larvae. These larvae migrate through the pet’s body over about six months, eventually reaching the heart and lungs. Adult heartworms can grow up to 12 inches long and release microfilariae (immature worms) into the bloodstream. The severity of the disease depends on worm load, duration, and the pet’s response.
Heartworm Treatment
If your pet tests positive, prompt treatment is necessary. Initial treatment aims to kill adult heartworms and involves careful staging through exams, X-rays, bloodwork, ECG, and urine tests. Severe cases may pose treatment risks. Adulticide injections are given three times, with close monitoring and hospitalization to manage reactions. Supportive care and pain management are provided. Pre-treatment with antibiotics is common. Monthly preventive medication helps eliminate young larvae, and pets are re-tested 4-6 months after treatment.
Post-Treatment Management
After treatment, activity should be strictly limited for 4-6 weeks. We recommend a follow-up antigen test 4-6 months post-treatment. If still positive, additional treatment or surgery may be needed.
For more information on heartworm prevention, please contact us at (817) 514-8387.
Dental Services in North Richland Hills
At Cornerstone Animal Hospital, we take pride in offering comprehensive dental services for your pets. Although dental disease is both common and harmful, it remains one of the most overlooked health issues in animals. If left untreated, the infection can spread through the bloodstream, potentially causing serious problems with the heart, liver, and kidneys.
What makes dental disease particularly concerning is how widespread it is. Studies show that about 80% of dogs and 70% of cats over the age of three suffer from some form of dental disease. Even with attentive care, this condition affects a surprisingly large number of pets.
Request an AppointmentWe believe the high prevalence is largely due to a lack of awareness among pet owners about the importance of dental health. There are many effective products available to help maintain your pet’s oral hygiene, but the key is consistent care. Brushing your pet’s teeth regularly remains the best way to prevent dental disease. Dental chews can also be a helpful addition to your pet’s routine when owners commit to maintaining good oral health.
Routine veterinary exams play a crucial role in maintaining dental health. Your veterinarian will always inspect your pet’s mouth during check-ups to detect early signs of dental disease and provide guidance on proper home care.
In some cases, your vet may recommend a professional dental cleaning under anesthesia. This allows us to thoroughly clean your pet’s teeth, including beneath the gums and other areas that are difficult to reach during home care.
After a professional cleaning, it is essential to continue brushing your pet’s teeth and providing dental chews to help prevent the return of dental disease.
Signs of dental disease include discolored teeth, bad breath, difficulty eating, and sometimes bleeding in the mouth. If you notice any of these symptoms, please schedule an exam as soon as possible.
If you have any questions about dental care or the services we offer, feel free to contact us today at (817) 514-8387.
Hospice & End of Life Care in North Richland Hills
End of Life Care in North Richland Hills
When the quality of your pet’s life seems to be fading, you will face one of life’s most difficult decisions. The Veterinarian and staff at Cornerstone Animal Hospital will be there with you and your pet with lots of empathy and support and will help you gain courage and comfort and also help you to decide if the time for the final decision has really arrived.
Your pet will be treated with the dignity and honor he/she deserves as a member of the family. Because we form such a strong bond with our companion animals, the end of a pet’s life can be a devastating experience. Everyone on the Cornerstone staff knows firsthand the grief and hurt you may be experiencing, and we will make sure you feel as comfortable as possible during this tough time.
How to make the final decision
Many a time some of the symptoms or behavioral changes in your beloved pets make you to think is it time to put him/her to sleep. The most common signs that prompt you to think that the final decision need to be made imminently in an older pet are the following
- Considerable weight loss over long period or on a fast pace
- Unable to stand or need help/support to move around
- Chronic pain not amenable to pain medications or other medical therapy
- Not interested in eating or drinking
- Loosing bowel or urinary control
- Cognitive disorders- do not respond to the master or show abnormal age–related behavior
- The pet is appearing to be suffering due to various other reasons
We can help with the Decision
In certain situations, the pet owner may not be able to make the right judgement due to emotional reasons or not fully understanding the medical or ethical validity of the decision. Also you may want to be doubly sure that the final decision is made appropriately and at the right time without the pet suffering from pain or other discomfort. The Veterinarian at Cornerstone Animal Hospital can be trusted in helping you make the right decision. The Veterinary doctor at this hospital do not encourage putting down a pet without valid reasons. The doctor and staff are well known for demonstrating genuine empathy to each pet parent and each pet and in giving a helping hand in making that transition of your pet very smooth and the most comforting experience you ever had.
Sedation
In order to make sure that your pet has a smooth and comfortable transition, every pet will receive sedation/anesthesia prior to euthanasia. Since every pet is different, we have several different types of sedation and anesthesia so that we can choose the right protocol for your situation. Most of the time, sedation will help make your pet very sleepy, but awake. Either way, they are pain free and very comfortable in your arms. Every pet will have an Intravenous catheter placed to facilitate when injecting the sedation.
Will my pet feel pain?
At Cornerstone Animal Hospital, we make sure that your pet will be relaxed and pain-free before and during the procedure. Pain medications may also be administered in addition to the sedation.
What will happen to my pet during the injection?
Since your pet will be already anesthetized, he/she will drift to sleep within few seconds of starting the IV injection. We use a heavy overdose of the anesthetic agent which will cause your pets heart to stop. He/she will pass away within seconds after the injection is given. The veterinarian will listen to your pet after the euthanasia injection has been given and will let you know when your pet has passed away.
Grieving Time
Losing a pet is similar to losing a family member. We understand that it is not an easy experience and that grieving is necessary. Everyone is different in their grieving process and we encourage families to allow everyone in the family to grieve differently. You may take your time to grieve the special relationship you had with your pet. Some people spend more time with their pet than extended family members and friends, so treat the loss accordingly.
After Care
At Cornerstone Animal Hospital, we understand that the life you shared with your companion is special and therefore we take care of the remains of your loved companion in an honorable manner. The options of after-care range from communal cremation, private cremation with ashes returned in an urn/box of your choice, or you can take care of the body by yourself. In order to cherish the sweet memories of sharing your life with the pet companion, Cornerstone Animal Hospital provide several pet memorial options. We can arrange your beloved pet’s paw prints on a clay or metal necklace with glass beads that contain the ashes. We will ensure that your pet’s memory lives on.

Request an AppointmentParasite Control in North Richland Hills
Parasite Prevention by Our North Richland Hills Veterinarian
What may seem like a minor nuisance to you can be dangerous and even life-threatening for your pet. Effective flea and tick prevention, stronger than typical over-the-counter treatments, can help you avoid serious health issues and the hassle of parasite infestations in your home. If your pet does have fleas or ticks, Cornerstone Animal Hospital offers professional flea treatments and safe tick removal at our clinic.
Dangers and Complications from Fleas and Ticks
Fleas can multiply rapidly, especially if unnoticed, leading to a full infestation in your home. Flea bites cause itching and discomfort for your pet and family, and can become infected. Fleas can also transmit diseases to your pet. Additionally, if your pet ingests fleas carrying worms, it can develop parasitic infections that deprive nutrients and, if untreated, can be fatal. Ticks carry diseases such as Lyme disease, which can severely affect your pet’s health over time.
Types of Flea and Tick Prevention
Spot-on treatments are commonly used by veterinary clinics for preventing fleas and ticks. This involves applying a liquid solution to your pet’s neck, which is secreted through sweat glands to repel and kill fleas and ticks on contact. These treatments are affordable and generally well-tolerated by pets.
Sprays are another option, involving an alcohol-based solution applied directly to your pet. Side effects are slightly more common with sprays compared to spot-on treatments. Oral medications are also available and provide full-body protection, including areas sprays cannot reach. Sometimes a combination of methods or adjusted dosages is recommended to effectively protect against both fleas and ticks.
Treating Fleas and Ticks at Cornerstone Animal Hospital
If your pet becomes infested with fleas or ticks, our North Richland Hills veterinarians can help. Using sprays or spot-on treatments, we eliminate fleas from your pet. For ticks, we provide safe removal and can test ticks for diseases. We also offer treatments for your home to remove the source of infestation.
To schedule flea or tick prevention or treatment, contact our North Richland Hills veterinary office at Cornerstone Animal Hospital by calling (817) 514-8387.

Anesthesia
At Cornerstone Animal Hospital, we prioritize the safety of your beloved pets just as your family doctor does for you. We tailor anesthetic protocols to each patient’s species (from large dogs to pocket pets), age (young to senior), and health conditions (healthy or with heart, liver, or kidney concerns). Our use of modern anesthetic medications ensures a safe and comfortable experience for all patients.
Anesthesia Monitoring
Our experienced staff use advanced digital monitoring equipment to continuously track heart rate, respiration, oxygen saturation, blood pressure, body temperature, and other vital signs throughout the procedure. Placement of an intravenous (IV) catheter and administration of IV fluids are standard for any major anesthesia. While anesthesia carries some risk, the benefits generally outweigh these when procedures are necessary.
All patients receive an IV catheter for fluid administration during anesthesia to maintain hydration. Our clinic is equipped with state-of-the-art monitoring devices including pulse oximetry (heart rate and oxygen saturation), electrocardiography (heart rhythm), respiratory monitoring, temperature, and blood pressure. This vigilant monitoring helps ensure your pet’s safety throughout anesthesia.
Does my pet need pre-anesthetic blood work?
We strongly recommend pre-anesthetic blood tests for all patients to assess organ function, clotting ability, and blood cell counts. Combined with a physical exam, this testing helps us evaluate anesthetic and surgical risks. Many conditions that could affect anesthesia safety may not show up on physical exam alone but can be detected through blood work.
Pain Management
We understand that surgery can cause pain, so we use advanced pain management protocols with medications before and after procedures to keep your pet comfortable. We also provide loving care, including phone updates for pet parents, cozy blankets, and lots of attention to make the experience as gentle as possible.
For more information about pet surgery, please don’t hesitate to contact us today at (817) 514-8387.
Cat Declawing in North Richland Hills
Cat Declawing in North Richland Hills
Cats naturally scratch as part of their behavior, but this can sometimes conflict with protecting your furniture or managing aggression. At Cornerstone Animal Hospital, we perform surgical declawing only when all other methods to prevent scratching have been exhausted. The procedure is carefully considered in situations where it may prevent a cat from being surrendered, mistreated, or euthanized.
Safe Cat Declawing in Southlake
Our veterinarians take every precaution to ensure a safe and compassionate experience for your cat. Prior to surgery, we perform pre-anesthetic blood work and utilize advanced, individualized anesthetic protocols. Pain management is a critical part of our recovery plan—we use safe, effective medications to ensure your pet’s comfort during and after the procedure.
We strongly advise that declawed cats be kept indoors, as they lose their primary means of defense and climbing.
Our highest priority is the well-being of every pet we treat. All of our procedures and policies are designed with their health and safety in mind.
Providing Quality Surgical Care for Your Cat
Declawing is considered as a last resort in cases where a cat exhibits aggressive behavior or cannot be trained to avoid destructive scratching. While many cats can be trained with proper techniques, others may not respond. In such instances, surgical declawing may reduce the risk of abandonment or euthanasia. Declawed cats should live exclusively indoors due to their limited ability to protect themselves. Although declawing can be performed at any age, younger cats generally recover more quickly.
Expert Feline Care at Our Animal Hospital in Colleyville
At Cornerstone Animal Hospital, we begin with pre-anesthetic blood tests to confirm your pet is healthy enough for anesthesia. The procedure is carried out using carefully selected anesthetics, continuous monitoring with multi-parameter equipment, and skilled surgical techniques. Pain is managed using a combination of nerve blocks, injectable pain relievers, and ongoing medication to minimize discomfort.
All surgical patients, including those undergoing declawing, receive intravenous fluids during the procedure through an IV catheter. Cats typically stay with us for the day following surgery to ensure a smooth and comfortable recovery.

Preventive Care in North Richland Hills

Why Does My Pet Need Preventive Health Care?
The veterinarians and staff at Cornerstone Animal Hospital place great importance on preventive care. As the saying goes, “An ounce of prevention is worth a pound of cure.” Preventing disease or detecting it early is far better than treating it once it has progressed.
Regular preventive health care from your North Richland Hills veterinarian helps protect your pet from unnecessary suffering and reduces financial burdens. Just as annual physical exams are recommended for people, routine physical examinations are highly recommended for pets as well.
Why Does My Pet Need a Physical Examination?
- Our pets cannot speak and don’t tell us when they feel unwell or show signs of internal illness. Regular examinations every six months, along with routine screening tests, help detect hidden diseases before symptoms appear.
- Pets, especially cats, often hide signs of illness until late in the disease progression, an instinct rooted in survival behavior within their pack or colony.
- Subtle signs like loss of appetite, vomiting, diarrhea, lethargy, or weight changes might be overlooked or mistaken for minor behavior changes but can indicate serious health issues. Older pets or those with medical conditions may require more frequent check-ups. At Cornerstone Animal Hospital, we strive to help your pet live a healthy life by identifying, treating, and preventing many health problems through regular exams.
- Examinations also provide an opportunity for our veterinarian and staff to discuss your pet’s lifestyle and design a health plan tailored to their needs. Vaccination requirements and options will be reviewed to decide the best care for your pet. Our pet care team will also guide you on diet, dental care, exercise, diagnostics, and vaccinations, adapting as your pet’s needs evolve. Below is an approximate pet age comparison to human years, which can vary by species, breed, and gender.

Pet Dermatology in North Richland Hills
Pet Dermatology in North Richland Hills
Just like people, pets can suffer from allergies and various skin issues. Visiting a veterinarian in North Richland Hills is the best way to treat rashes, skin irritation, or infections promptly. Regularly checking your dog or cat for signs of skin problems helps ensure a healthy lifestyle. Our veterinary team also serves pet owners in Keller, Colleyville, and Southlake. If you suspect your pet has a skin issue, don’t hesitate to contact our team today!
Request an AppointmentIrritation in Pets
If your pet has a flea problem, they may experience intense skin irritation. Symptoms such as hair loss, constant itching, and red bumps are common with flea infestations. Fleas can also cause stress and anxiety in pets due to persistent scratching or biting. It’s important to monitor your pet to prevent self-inflicted injuries. Our veterinarians can prescribe effective topical flea treatments to eliminate the infestation and prevent future outbreaks.
Pet Hair Loss
Hair loss in pets can be a symptom of an underlying skin condition. Itchy, irritated skin often leads pets to excessively lick or chew affected areas, resulting in fur loss. Our North Richland Hills veterinarian can diagnose the root cause and recommend proper treatment.
Skin Rashes
Unusual rashes on your pet may indicate allergies, parasites, or dietary issues. Treating rashes often involves lifestyle adjustments, including improved grooming and nutritional changes. Let our experienced team help you identify and address the source.
Pets Can Also Have Allergic Reactions
Pets can experience allergic reactions from food, flea bites, or environmental factors. If your pet shows signs of itchiness or raised bumps, our veterinarians can perform tests to determine the cause and prescribe medication to relieve symptoms. Regular baths can also help reduce allergens on their skin and coat.
Flea-Induced Skin Problems
Fleas are more than just a nuisance—they can seriously impact your pet’s health. By biting and feeding on your pet’s blood, fleas cause discomfort and potential skin infections. At Cornerstone Pet Dermatology, we provide effective treatment and prevention strategies. Call us today to schedule an appointment!
Flea Allergic Dermatitis (FAD)
Frequent scratching could be a sign of flea allergy dermatitis (FAD), a common condition in pets sensitive to flea saliva. Some pets are born with this allergy, while others develop it over time. Our veterinarians are trained to diagnose and treat FAD with medications such as Cytopoint® and Apoquel®. Cytopoint provides 4–8 weeks of relief with a single injection, while Apoquel helps control allergic reactions and reduce itching. Call us today to learn more!
Food as a Cause of Skin Problems
If your pet regularly experiences itchiness, redness, sores, or hair loss, their food may be to blame. Common allergens include chicken, soy, wheat, and beef. At Cornerstone Pet Dermatology, we offer allergy testing to identify dietary triggers and can design a custom meal plan to meet your pet’s unique needs. Contact us to book an appointment!
Hormonal Imbalances
Hormonal imbalances like hypothyroidism or Cushing’s disease can lead to skin issues such as oily or thinning skin, hair loss, bad odor, and excessive itching. These conditions may also cause serious health concerns if left untreated. Our veterinary team can perform diagnostics to check for glandular disorders and help your pet feel their best.
Immunotherapy for Skin Diseases
If standard treatments such as flea control, diet changes, and allergy medications have not resolved your pet’s skin issues, immunotherapy may be a solution. This therapy works by modifying the immune system’s response to allergens and can be administered as injections or oral drops. Treatment typically continues for at least one year for best results. We also offer oral medications like Apoquel and injectable options like Cytopoint to help manage chronic conditions. Contact us to learn more about immunotherapy options for your pet.

Pet Illness in North Richland Hills
Discuss Pet Illness With Our Cornerstone Animal Hospital
Just like humans, pets can fall ill unexpectedly and require the care of a skilled veterinarian. At Cornerstone Animal Hospital in North Richland Hills, TX, our veterinarians are fully equipped to provide a comprehensive range of services.
Emergency versus Urgent Care
Caring for a sick pet can be stressful, and it’s often difficult to determine whether your pet’s condition requires urgent or emergency care. Here’s how to tell the difference:
- Emergency Pet Care. This care is for life-threatening situations. Clear emergencies include collapse, unconsciousness, broken bones, severe wounds, heavy bleeding, and poisoning symptoms.
- Urgent Care for Your Pet. These issues aren’t as severe as emergencies but still require prompt attention. Examples include not eating or drinking, difficulty urinating or defecating, and minor cuts. If you’re unsure, feel free to call our North Richland Hills office for guidance from our team.
Why Would a Pet Visit a Vet?
Here are 10 common reasons pets are brought to the vet:
- Soft tissue injury (bruises and contusions)
- Skin allergy or infection
- Skin mass or tag
- Ear infection
- Dental disease
- Urinary tract infection or kidney disease
- Diabetes
- Vomiting and/or diarrhea
- Not eating or drinking
- Arthritis
Symptoms to Watch For
Since pets can’t tell us where they hurt or how they feel, knowing their normal behavior and recognizing changes is essential. If needed, seek veterinary care promptly. Watch for these signs:
- Vomiting or diarrhea. Occasional vomiting may occur if pets eat too fast or play right after eating, but repeated vomiting over 24 hours requires a vet visit. Occasional diarrhea may not be serious, but persistent episodes could indicate gastrointestinal issues needing veterinary attention.
- Not eating. Missing one meal might be okay, but skipping multiple meals needs evaluation.
- Lethargy.
- Hair loss, itchy skin, or rash.
- Excessive urination or urinating in unusual places.

Euth Decision
How to Make the Final Decision
There are times when changes in your beloved pet’s behavior or health lead you to wonder if it’s time to say goodbye. The following are common signs in older pets that may indicate the need for this difficult decision:
- Significant weight loss, either gradual or rapid
- Inability to stand or requiring assistance to move
- Chronic pain that does not respond to medication or treatment
- Lack of interest in eating or drinking
- Loss of control over bowel or bladder functions
- Cognitive decline—lack of response to owners or abnormal age-related behaviors
- Visible suffering due to various health issues
We Can Help with the Decision
Making the right choice can be challenging, especially when emotions are involved or when medical and ethical aspects are unclear. You may want to be certain that the decision is made at the right time, minimizing any pain or discomfort for your pet. At Cornerstone Animal Hospital, our veterinarians are here to support you through this process. We do not encourage euthanasia without valid reasons. Our team is known for their compassion and empathy, helping pet parents and their pets experience this transition with the utmost comfort and care.
For more information or support regarding euthanasia decisions, please don’t hesitate to contact us today at (817) 514-8387.

Our 5 Star Ratings from clients
We greatly value the kind words shared by our clients. Their positive experiences reflect our commitment to excellent care. We appreciate their trust and are dedicated to continuing to provide high-quality services to everyone we serve.Friendly staff and great care for our senior dog.
The staff is amazing, caring and very informative ! I feel, I have found a permanent Veterinary Hospital for my English Bulldog, he loved the staff too ! Oh yeah, the Doctor is great also ! The prices are very fair, you dont feel like you are going to be taken to the cleaners caring for your fur baby, they explain everything up front Ya'll keep up the good work !!
We took our 14 year old cat in because she was not eating and lethargic. The office staff was able to get us in quickly on a Friday afternoon. Stormy was super sweet and helpful. Dr. Thomas was great as were the other office staff. Thankfully, bloodwork came back good so went home with some medication to increase her appetite. We will definitely be back!
My pup has been seen at Cornerstone for about 4+ years now and after many regular visits, and visits that require more attention, this animal hospital has been the most kind! Front desk staff goes above and beyond to make us feel welcome (although my pup has an ungodly amount of anxiety) and are extremely timely right when we arrive. I don’t know what goes on behind the closed doors during the exams and such, but I trust that she is well taken care of back there. Another highlight I must include is pricing. I was 19 and a college student when I adopted my dog with full financial responsibility of her. Cornerstone was the only vet, after days of research, that I was able to afford anesthesia bills when she had a paw procedure done. She a teeth cleaning done more recently and I was expecting bills to be a lot higher due to the economy, yet it was still absolutely affordable for the whole process. Thanks Cornerstone!
I will not take my dog anywhere else. They treat him as it there own pet. Everyone is very professional.
