Dr. Roy Madigan, D.V.M., is not just a veterinarian. He is one of the leading experts in canine Chagas disease in the United States.
<br><br>
• Founder of Vida Pharmacal, focused on breakthrough parasitic disease treatments
<br>• Filed the first veterinary drug patent for anti-T. cruzi activity in dogs
<br>• Principal scientist for the U.S. military working dog Chagas treatment study
<br>• Veterinary lead for the Texas Chagas Task Force alongside the CDC and UT Health
<br>• Pioneer in developing diagnostic and treatment protocols for infected dogs
<br><br>
Your pet is being treated by the same expert helping shape how Chagas disease is understood nationwide.

Get In Touch

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

<b>Early Detection. Advanced Treatment. Led by One of the Nation’s Top Experts.</b>

<b>Do not wait for symptoms to appear.</b>

Chagas disease is often silent early on, but warning signs may include:
<br>
<br>• Lethargy or decreased activity
<br>• Fainting or collapse
<br>• Irregular heartbeat
<br>• Difficulty breathing
<br>• Unexplained weight loss
<br><br>
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 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.

At Central Texas Vet, we go beyond standard testing.
Dr. Madigan is actively developing advanced serologic testing methods to improve detection accuracy.
<br><br>
Your dog’s evaluation may include:
<br>
<br>• Comprehensive physical exam
<br>• Cardiac screening
<br>• Specialized blood testing for T. cruzi
<br>• Advanced diagnostics when needed
<br><br>
Early detection allows for better management and improved outcomes.

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.
<br><br>
Without intervention, Chagas can lead to:
<br>
<br>• Heart disease
<br>• Arrhythmias
<br>• Sudden death

<p dir="auto">Sometimes, it can be hard to tell when you should call your veterinarian or when you should wait and see. One of the key aspects of pet ownership is understanding when our beloved furry friends need professional medical attention. Not every sneeze or scratch necessitates a trip to the vet, but recognizing when something is amiss and seeking timely veterinary care is crucial. The following information is a general guideline, but if you are at all concerned about your pet, you should always call your veterinarian!</p><h2 dir="auto" style="text-align: left; line-height: 1.2"><strong>Illness for a veterinarian visit:</strong></h2><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Lethargy (tiredness)</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If your pet has non-specific lethargy and is not showing any signs of pain and seems to be acting fine otherwise (i.e., still eating, drinking, going to the bathroom normally), you can usually wait 24 hours. Make sure your pet has nice pink gums. If their gums are pale or white/grey in appearance, then do not wait and call your veterinarian right away.</p><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Vomiting</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If your pet vomits one time but is acting fine otherwise, this is usually not cause for concern. If your pet vomits and has diarrhea, lethargy, decreased appetite, or has gotten into something and/or is just not acting like themselves, you should call your veterinarian. If your pet vomits more than once in 24 hours, you should call your veterinarian right away. (Dog owners, be sure to educate yourself on <strong>bloat</strong>.) The exception to this is if you have a cat that is bringing up a hairball. They will often vomit up more than one hairball in 24 hours.</p><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Diarrhea</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If your pet has one episode of diarrhea in 24 hours and is acting fine otherwise, you can usually sit and wait. If your pet has more than one episode of diarrhea in 24 hours, you should call your veterinarian. If you see blood in diarrhea or the diarrhea is black, call your veterinarian right away. If your pet has diarrhea and is vomiting, is lethargic, has a decreased appetite, has gotten into something, or is just not acting like himself, call your veterinarian.</p><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Decreased Appetite or Anorexia</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If your pet has decreased appetite for less than 24 hours and is acting fine otherwise, you can usually wait 24 hours. If your pet is not eating at all, do not wait and call your veterinarian right away. If your pet is acting abnormally and has a decreased appetite, call your veterinarian. If your pet has a decreased appetite or has not eaten for more than 24 hours, call your veterinarian. A decreased appetite or lack of appetite is very <strong>serious in cats</strong> since they can decline quickly.</p><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Increased Frequency of Urination</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If you notice your pet in the litterbox more frequently, asking to go out to potty more frequently, or seeing them urinating more frequently, you should call your vet. If you notice blood in the urine, call your veterinarian. It is also helpful to bring a freshly collected urine sample with you to your appointment. Make sure your pet is producing urine, especially in cats.</p><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Decreased Urine Volume</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If you notice your pet trying to urinate more frequently and very little urine is coming out, call your vet. If you notice no urine, call your vet immediately. This is especially true in cats. If you notice a few drops of urine or no urine production, call your veterinarian immediately because your pet could have a <strong>urinary obstruction,</strong> which is a life-threatening emergency.</p><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Increased Appetite</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If you notice your pet has an increased appetite, especially in cats, this can be a sign of an underlying problem. If your pet has an increased appetite for more than a few days and it is not due to increased activity, call your veterinarian.</p><h3 dir="auto" style="text-align: left; line-height: 1.2"><strong>Changes in Weight</strong></h3><p dir="auto" style="text-align: left; line-height: 27px">If you notice that your pet is losing or gaining weight without any changes in activity or diet, you should <strong>take your pet in for a physical exam</strong>. There are many conditions that cause weight loss that can become life-threatening if not diagnosed and managed properly. There are also medical conditions that cause weight gain that may need to be managed.</p><p dir="auto" style="text-align: left; line-height: 27px">Our pets bring a lot of joy to our lives. They are also very good at hiding illness, pain, etc. If you are at all concerned about the health of your pet, contact your veterinarian. One of the biggest mistakes in animal care that pet owners make is taking a sit-and-wait attitude when it is something that should have been seen days or weeks before. Cats, in particular, are great pretenders. They often don’t show how ill they are until they are in dire straits.</p><h4 dir="auto" style="text-align: left; line-height: 1.2"><strong>If you are ever on the fence about whether or not you should call your veterinarian, trust your gut and call!</strong></h4><p dir="auto"></p>

The following information is a general guideline, but if you are at all concerned about your pet, you should always call your veterinarian!

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

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

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

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

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

Pet Surgeries

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

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


Advanced Diagnostic Imaging

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

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.
