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

Questions? We Have Answers

If your dog may be at risk, schedule an evaluation today and get answers from one of the leading experts in the field.

<h1 dir="auto">Pet Cancer Awareness Month: Small Changes Worth Paying Attention To</h1><p dir="auto"></p><p dir="auto">November is Pet Cancer Awareness Month, an important reminder to pay attention to the little changes in your pet's health.</p><p dir="auto"></p><p dir="auto">Cancer can affect dogs and cats of all ages, although the risk of many cancers increases as pets get older. Because early symptoms aren't always obvious, understanding what's normal for your pet can help you recognize when something needs veterinary attention.</p><h2 dir="auto">Small Changes That Could Signal a Health Concern</h2><p dir="auto"></p><p dir="auto">Not every health concern comes with obvious symptoms. Sometimes, the first signs are changes in your pet's everyday habits.</p><p dir="auto"></p><p dir="auto">Pay attention to:</p><ul><li><p dir="auto">Appetite changes: Eating less, difficulty chewing, or unexplained weight loss.</p></li><li><p dir="auto">New lumps or bumps: Growths that appear suddenly or change in size or appearance.</p></li><li><p dir="auto">Lower energy levels: Sleeping more, avoiding activities, or becoming less playful.</p></li><li><p dir="auto">Behavioral changes: Hiding, restlessness, or acting differently than usual.</p></li><li><p dir="auto">Mobility issues: Persistent limping, stiffness, or discomfort.</p></li><li><p dir="auto">Bathroom changes: Difficulty urinating or defecating, or blood in the urine or stool.</p></li></ul><p dir="auto"></p><p dir="auto">These symptoms don't necessarily mean your pet has cancer, but they shouldn't be ignored. A veterinary examination can help determine what's causing them.</p><h2 dir="auto">Why Knowing Your Pet's Normal Matters</h2><p dir="auto"></p><p dir="auto">You know your pet's personality and routines better than anyone. That makes you an important part of recognizing potential health concerns.</p><p dir="auto"></p><p dir="auto">Notice how much your pet typically eats, how active they are, and how they behave throughout the day. If something changes and doesn't return to normal, it's worth discussing with your veterinarian.</p><p dir="auto"></p><p dir="auto">Regularly checking your pet for new lumps or unusual skin changes can also help you identify concerns between appointments.</p><h2 dir="auto">The Role of Routine Veterinary Care</h2><p dir="auto"></p><p dir="auto">Even when your pet seems healthy, regular wellness visits are important.</p><p dir="auto"></p><p dir="auto">During these appointments, your veterinarian can perform a physical examination, evaluate changes in your pet's health, and recommend additional testing when appropriate.</p><p dir="auto"></p><p dir="auto">Bloodwork, imaging, or other diagnostic tests may be recommended based on your pet's symptoms, age, and medical history. While routine bloodwork cannot detect most cancers on its own, it can provide valuable information about overall health.</p><p dir="auto"></p><p dir="auto">For senior pets, more frequent wellness visits may be recommended to help monitor age-related changes.</p><h2 dir="auto">What Happens If Cancer Is Suspected?</h2><p dir="auto"></p><p dir="auto">If your veterinarian identifies a concerning symptom or growth, the next step may involve diagnostic testing to better understand the cause.</p><p dir="auto"></p><p dir="auto">Depending on the findings, your veterinarian may recommend imaging, a needle aspirate, a biopsy, or a consultation with a veterinary specialist.</p><p dir="auto"></p><p dir="auto">If cancer is diagnosed, treatment options depend on the type of cancer and your pet's overall health. Some pets may benefit from surgery, chemotherapy, radiation therapy, or supportive care focused on maintaining comfort and quality of life.</p><h2 dir="auto">Frequently Asked Questions About Pet Cancer</h2><h3 dir="auto">1. Are all lumps on pets cancerous?</h3><p dir="auto"></p><p dir="auto">No. Many lumps are benign, but only a veterinary evaluation and, when needed, diagnostic testing can determine whether a growth is concerning.</p><h3 dir="auto">2. Can pets have cancer without showing symptoms?</h3><p dir="auto"></p><p dir="auto">Yes. Some cancers may develop without noticeable symptoms in their early stages, which is one reason routine veterinary examinations are important.</p><h3 dir="auto">3. Are senior pets more likely to develop cancer?</h3><p dir="auto"></p><p dir="auto">The risk of many types of cancer increases with age. Senior pets may benefit from wellness examinations every six months, depending on their individual health needs.</p><h3 dir="auto">4. Can cancer in pets be treated?</h3><p dir="auto"></p><p dir="auto">Yes. Depending on the diagnosis, treatment may include surgery, medications, chemotherapy, radiation therapy, or supportive care. Your veterinarian can help determine the most appropriate options.</p><h3 dir="auto">5. When should I contact my veterinarian?</h3><p dir="auto"></p><p dir="auto">Schedule an appointment if you notice a new lump, unexplained weight loss, persistent appetite changes, unusual behavior, or other ongoing health concerns.</p><h2 dir="auto">Stay Proactive About Your Pet's Health</h2><p dir="auto"></p><p dir="auto">Pet Cancer Awareness Month is a reminder that small changes can sometimes tell us something important about our pets' health.</p><p dir="auto">By staying familiar with your pet's normal habits and keeping up with routine veterinary care, you can help ensure potential concerns receive timely attention.</p>
