Your pet is being treated by the same expert helping shape how Chagas disease is understood nationwide.

Chagas disease is caused by the parasite Trypanosoma cruzi, transmitted by “kissing bugs” commonly found in Texas.Once infected, dogs may appear normal while the parasite attacks the heart and other organs.Without intervention, Chagas can lead to:<ul><li>Heart disease</li><li>Arrhythmias</li><li>Sudden death</li></ul>

Early Detection. Advanced Treatment. Led by One of the Nation’s Top Experts.

Do not wait for symptoms to appear.

Chagas disease progresses in stages. The earlier it is identified:<ul><li>The more treatment options are available</li><li>The better heart damage can be managed</li><li>The higher the chance of improving quality of life</li></ul>Waiting can mean irreversible cardiac damage.

If your dog may have been exposed to kissing bugs, do not wait. Chagas disease can silently damage the heart before symptoms appear. Early diagnosis can make the difference.

Chagas disease is often silent early on, but warning signs may include:<ul><li>Lethargy or decreased activity</li><li>Fainting or collapse</li><li>Irregular heartbeat</li><li>Difficulty breathing</li><li>Unexplained weight loss</li></ul>If your dog spends time outdoors, lives in Central Texas, or has been exposed to insects, they may be at risk even without symptoms.

If your dog may be at risk, schedule an evaluation today and get answers from one of the leading experts in the field.

Virtual Vet Care

Ensure your pet travels safely with veterinary health certificates and travel documentation support. Our veterinarians provide exams, guidance, and required paperwork to help prepare your pet for travel based on your destination and specific requirements.

Pet Health Certificates

Saying goodbye is the hardest part of loving a pet. When that time comes, you deserve clarity, comfort, and the space to make decisions with peace of mind.

End-of-Life Support

When your pet needs medication, trust and convenience matter. At (), we prescribe and dispense medications directly from the team whos seen your pet, knows their health history, and understands their specific needs.
No guessing, no delays, and no unnecessary confusion.


Pet Prescriptions

Skin issues are one of the most common reasons pets end up at the vet, and they're also some of the most frustrating. Allergies, infections, or even food sensitivities can all cause your pet discomfort.

Dermatology & Allergy Care

When pets act out, there's almost always a reason. Anxiety, fear, medical conditions, or past trauma can show up as barking, biting, hiding, or destruction. Our job is to uncover the cause and help your pet feel safe again.

Pet Behavior & Anxiety Support

Nutrition is the foundation of good health, and a powerful tool in managing weight, energy, chronic conditions, and even behavior.

Pet Nutrition

A sudden limp. A skipped meal. A look that says something's off. When your pet isn't feeling right, same-day answers make all the difference. 

Urgent Care

Your pet can't tell you when something's wrong. That's why regular wellness exams are so important. These visits give us the chance to catch health issues early, before they become painful or costly.  

Wellness Exams

Bad breath isn't just annoying - it's often a sign of deeper health issues. Dental disease in pets can lead to oral pain, local or systemic infection, tooth loss, and even heart, liver, or kidney complications. 

Dental Care

Fleas, ticks, and intestinal worms are not just a nuisance, they are dangerous. These tiny pests can cause serious health issues like Lyme disease, heartworm disease, and tapeworms. 

Parasite Prevention

Vaccines are one of the most important tools we have to protect pets from serious, often deadly diseases. Whether you have a rambunctious or a relaxed pet, vaccinations help your pet build strong immunity and avoid preventable illness.

Vaccinations

Comprehensive surgical services, from routine procedures to complex operations, all are performed with expert care.

Pet Surgeries

When your pet isn't acting like themselves, diagnostic testing helps us find the reason. From bloodwork, urine testing, and fecal exams to x-rays, these tests give us a window into what's happening inside, so we can take action before things get worse.

Diagnostic Testing

When pets get sick or injured, you want answers fast. Advanced imaging gives us a deeper look, without invasive procedures.


Advanced Diagnostic Imaging

Permanent ID for Peace of Mind. A collar can come off. A tag can get lost. But a microchip is a permanent, tamper-proof way to make sure your pet always has a way home. At (), we offer safe and simple microchip implantation, so your pet stays connected to you, no matter what.

Pet Microchipping

Discover hidden dental issues before they cause pain with pet dental radiology at (). Our veterinary dental X-rays reveal infections, bone loss, and tooth damage beneath the gum line, ensuring safer, more effective treatment. Non-invasive and included in every comprehensive dental cleaning, dental radiographs for pets help protect your pet's health, comfort, and smile for years to come.


Dental Radiology

Spaying or neutering your pet is one of the most important decisions you can make for their long-term health. It helps prevent certain cancers and infections, curbs unwanted behaviors, and reduces the number of orphaned pets in shelters.
