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

Questions? We Have Answers

<h1 dir="auto">Halloween Safety for Pets: Tips for a Safe and Less Stressful Holiday</h1>Halloween can be a fun night for families, but some of the things that make the holiday exciting for people can be stressful or potentially dangerous for pets. Frequent visitors, costumes, unfamiliar noises, candy, and decorations can all introduce new risks for dogs and cats.Preparing ahead can help you create a safer environment and make Halloween more comfortable for your pet.<h2 dir="auto">1. Keep Halloween Candy Away From Pets</h2>Candy bowls and trick-or-treat bags can be tempting for curious pets, but several common Halloween treats can be harmful if eaten.Keep an eye out for:<ul><li>Chocolate: Chocolate can be toxic to pets, particularly dogs, and may cause serious health problems depending on the type and amount consumed.</li><li>Xylitol: This artificial sweetener is sometimes found in sugar-free candy and gum and can be extremely dangerous for pets.</li><li>Raisins: Raisins can cause serious kidney problems in dogs.</li><li>Candy wrappers: Foil, plastic, and other wrappers can become lodged in the digestive tract if swallowed.</li></ul>Keep Halloween treats and discarded wrappers somewhere pets cannot reach. If you think your pet has eaten something potentially harmful, contact your veterinarian or an emergency veterinary hospital promptly.<h2 dir="auto">2. Prevent Accidental Escapes</h2>A front door that repeatedly opens for trick-or-treaters can give pets an opportunity to slip outside. Unfamiliar costumes, crowds, and noises may also frighten a pet once they're outdoors.Consider keeping your pet in a secure area away from frequently opened doors. A closed room, crate, or pet gate can provide an additional barrier while visitors are arriving.This is also a good time to make sure your pet's identification is current. Check their ID tag and make sure their microchip registration includes your current contact information. Up-to-date identification can make it easier to reunite with your pet if they get lost.<h2 dir="auto">3. Help Reduce Halloween Anxiety</h2>Halloween introduces sights, sounds, and smells that pets don't encounter every day. Costumes, crowds, decorations, doorbells, and repeated knocking can be especially stressful for pets who are sensitive to noise or unfamiliar people.Signs of anxiety may include pacing, panting, trembling, hiding, barking, vocalizing, or trying to escape.If your pet tends to become anxious, create a quiet retreat away from the activity. Familiar bedding and favorite toys can help make the space more comfortable, while calming music or white noise may help reduce outside sounds.If you expect your pet to experience significant anxiety, talk with your veterinarian before Halloween. Your veterinary team can discuss strategies and determine whether an anxiety aid or medication may be appropriate for your pet.<h2 dir="auto">4. Choose Costumes Carefully</h2>Not every pet enjoys dressing up. If your dog or cat isn't comfortable wearing clothing, it's best to skip the costume rather than create unnecessary stress.For pets who are comfortable dressing up, choose a costume that:<ul><li>Allows them to move normally</li><li>Does not interfere with breathing or vision</li><li>Uses comfortable materials that won't irritate their skin</li><li>Does not have small or loose pieces that could be chewed or swallowed</li></ul>Always supervise a pet while they're wearing a costume and remove it if they show signs of discomfort or distress.<h2 dir="auto">5. Be Mindful of Halloween Decorations</h2>Halloween decorations can be interesting to curious pets, but some can create safety hazards.Jack-o'-lanterns with lit candles can be knocked over and create a fire risk. Hanging decorations, artificial cobwebs, string lights, and small accessories may become choking, strangulation, or intestinal obstruction hazards if pets play with or swallow them.Electrical cords should also be kept away from pets who may chew them. Glow sticks should remain out of reach as well. While the liquid inside isn't considered toxic, chewing a glow stick can cause mouth irritation, drooling, or vomiting, and pieces of plastic can cause additional problems if swallowed.When decorating, consider whether your pet can reach, chew, or become tangled in each item.<h2 dir="auto">Prepare Before Halloween Arrives</h2>A safer Halloween starts with a little planning. Keep candy and decorations out of reach, secure doors and exits, and give your pet somewhere quiet to retreat if the evening becomes overwhelming.If you already know your pet struggles with visitors, loud noises, or changes in routine, don't wait until Halloween night to make a plan. Your veterinary team can help you determine the best way to manage your pet's anxiety and keep them comfortable during the holiday.Concerned about how your pet will handle Halloween? Schedule an appointment with our veterinary team before the holiday to discuss their anxiety, behavior, and individual needs.

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.

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

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

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.
