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

<h2 dir="auto"><strong>Year-Round Parasite Prevention for Pets in Andover, MA</strong></h2><p dir="auto"><strong>Peace of Mind from Pests You Cannot See</strong></p><p dir="auto"></p><p dir="auto">At Andover Animal Hospital, we believe the best way to protect pets from parasites is through proactive prevention. Our veterinary team creates customized parasite prevention plans based on your pet’s lifestyle, age, environment, and risk factors.</p><p dir="auto">Whether your dog enjoys hiking local trails, your cat spends time outdoors, or you share your home with a rabbit, bird, or exotic companion animal, we will recommend preventive care options designed to support their long-term health.</p><p dir="auto">Conveniently located at 233 Lowell St in Andover, MA, our hospital helps protect pets throughout the region from common parasites and the diseases they carry.</p><h2 dir="auto"><strong>What Parasites Are We Protecting Against?</strong></h2><p dir="auto"><strong>Fleas</strong></p><p dir="auto">Fleas can cause severe itching, allergic skin reactions, hair loss, and secondary skin infections. They may also transmit tapeworms and other blood-borne pathogens.</p><p dir="auto"><strong>Ticks</strong></p><p dir="auto">Ticks are especially common throughout Massachusetts and New England and can transmit dangerous illnesses including Lyme disease, Ehrlichiosis, and Anaplasmosis.</p><p dir="auto"><strong>Heartworms</strong></p><p dir="auto">Heartworms are spread by mosquitoes and live within the heart, lungs, and blood vessels. Without treatment, heartworm disease can become life-threatening.</p><p dir="auto"><strong>Intestinal Parasites</strong></p><p dir="auto">Roundworms, hookworms, whipworms, and tapeworms can affect digestion, nutrient absorption, weight, and energy levels. Some intestinal parasites may also pose zoonotic risks to humans.</p><h2 dir="auto"><strong>Your Pet’s Customized Prevention Plan</strong></h2><p dir="auto">No two pets have the same lifestyle or parasite exposure risk. Our veterinary team considers your pet’s:</p><ul><li><p dir="auto">Age</p></li><li><p dir="auto">Species</p></li><li><p dir="auto">Lifestyle</p></li><li><p dir="auto">Outdoor activity</p></li><li><p dir="auto">Travel history</p></li><li><p dir="auto">Medical history</p></li></ul><p dir="auto">Before recommending the most appropriate preventive care plan.</p><p dir="auto">Treatment and prevention options may include:</p><ul><li><p dir="auto">Monthly chewable preventatives</p></li><li><p dir="auto">Topical flea and tick medications</p></li><li><p dir="auto">Long-acting injections</p></li><li><p dir="auto">Deworming treatments</p></li><li><p dir="auto">Combination parasite prevention products</p></li></ul><p dir="auto">We also recommend regular bloodwork and fecal testing because some parasite-related illnesses, including heartworm disease and certain tick-borne infections, may not show visible symptoms until they become more advanced.</p><h2 dir="auto"><strong>Parasite Prevention for Dogs, Cats, and Small Companion Pets</strong></h2><p dir="auto">Dogs and cats are not the only pets affected by parasites. Rabbits, pocket pets, birds, and exotic companion animals may also experience parasite-related health concerns depending on their species, environment, and lifestyle.</p><p dir="auto">Our veterinary team provides preventive guidance and wellness recommendations tailored to the specific needs of each pet.</p><p dir="auto"></p><h2 dir="auto"><strong>Year-Round Protection is the Best Protection</strong></h2><p dir="auto">Parasites do not disappear during colder months. Many fleas, ticks, and intestinal parasites survive indoors or remain active during milder weather conditions throughout the year.</p><p dir="auto">That is why we recommend consistent, year-round parasite prevention for pets in Andover, MA. Preventive care is typically safer, easier, and more affordable than treating an active infestation or advanced disease.</p><p dir="auto">And if your pet develops a parasite-related illness, our veterinary team is here with diagnostic testing, treatment options, and supportive care.</p><h2 dir="auto"><strong>Keep the Bugs Away</strong></h2><p dir="auto">Protecting your pet from fleas, ticks, heartworms, and intestinal parasites is an essential part of lifelong wellness care.
