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.
 
• Founder of Vida Pharmacal, focused on breakthrough parasitic disease treatments
 • Filed the first veterinary drug patent for anti-T. cruzi activity in dogs
 • Principal scientist for the U.S. military working dog Chagas treatment study
 • Veterinary lead for the Texas Chagas Task Force alongside the CDC and UT Health
 • Pioneer in developing diagnostic and treatment protocols for infected dogs
 
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:
 
 • The more treatment options are available
 • The better heart damage can be managed
 • The higher the chance of improving quality of life
 
Waiting can mean irreversible cardiac damage.

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

Do not wait for symptoms to appear.

Chagas disease is often silent early on, but warning signs may include:
 
 • Lethargy or decreased activity
 • Fainting or collapse
 • Irregular heartbeat
 • Difficulty breathing
 • Unexplained weight loss
 
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.
 
Your dog’s evaluation may include:
 
 • Comprehensive physical exam
 • Cardiac screening
 • Specialized blood testing for T. cruzi
 • Advanced diagnostics when needed
 
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.
 
Without intervention, Chagas can lead to:
 
 • Heart disease
 • Arrhythmias
 • Sudden death
