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.

<h3 dir="auto" style="line-height: 1.2">What Is Leptospirosis</h3>Leptospirosis is a disease that most dog owners have either never heard of or it sounds familiar, but they’re not sure what it is. Leptospirosis is a bacterial infection that can cause liver and kidney failure in dogs and can be contracted by humans. Leptospira is most commonly found in wet environments and is commonly shed in the urine of wildlife. Your dog can be infected with leptospires either directly through infected tissue (i.e., a dead animal) or secretions (most commonly urine) and can also be contracted through indirect contact from contaminated water, soil, or food. Common routes of infection include drinking contaminated water or entering the body through a cut or mucous membranes (eyes, nose, or mouth). Once leptospires enter the environment, they can live for months in the soil and are easily washed into bodies of water, including puddles.<h3 dir="auto" style="line-height: 1.2">Diagnosing Leptospirosis</h3>Leptospirosis in dogs can be hard to diagnose because the clinical signs are often nonspecific. Common clinical signs include lethargy, fever, anorexia, vomiting, diarrhea, and weakness. Often, elevated kidney and/or liver values will also be seen on bloodwork. Your veterinarian may be suspicious of leptospirosis based on clinical signs, vaccination status, and the likelihood of your dog being exposed to it. If your veterinarian is suspicious of leptospirosis, they will probably recommend specialized blood and urine testing.<h3 dir="auto" style="line-height: 1.2">Treatment For Leptospirosis</h3>If your dog is positive for leptospirosis, treatment with antibiotics will be started, since it is a bacterial disease. Additional treatment will be needed if there is kidney or liver injury, which may include hospitalization with supportive care. Your veterinarian may also recommend that you contact your physician about possible exposure. The sooner that leptospirosis is diagnosed and treated, the better the chance of recovery.There are many different serovars (strains) of Leptospira. Vaccines are available that protect against the four most common serovars that cause leptospirosis in dogs. No vaccine is 100% effective, and there is the possibility that your dog could come into contact with a less common serovar. When possible, try to limit your dog’s contact with dead animals, wildlife, and stagnant water.When detected early, leptospirosis can have a good outcome with proper treatment and supportive care. Discuss with your veterinarian if your dog is at risk and if vaccination is appropriate for your dog. Leptospirosis can be fatal, and there is the possibility that you could get infected by your dog.

Speciality Services

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

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

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

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.

Spay And Neuter

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.
