Chagas Frequently Asked Questions
What is Chagas’ disease?
Chagas disease is caused by the parasite Trypanosoma cruzi, and is spread by triatomine bugs, also known as kissing bugs. They are endemic in the southern United States, Latin America and South America. The symptoms of Chagas can easily be mistaken for other illnesses and diseases, so it is often misdiagnosed. Chagas disease in dogs can be a silent killer, and it is not well known or tested for, as we discovered when we set out to educate ourselves. In dogs, the primary effect is usually heart disease and or sudden death left untreated.
Why is TracyPaws Rescue now testing all dogs for Chagas?
In August 2020, we lost several dogs to sudden death. All of the dogs appeared healthy and had no visible signs of illness. They died suddenly and necropsies showed Chagas disease. We were devastated. We had never seen this before in the ten years we have been rescuing dogs. All dogs coming into our program are now tested for Chagas disease.

What should I consider if I want to adopt a Chagas positive dog?
We are looking for extra special adopters for these dogs. The people who will love these dogs as much as we do. The Chagas positive dogs will remain in our care and on treatment for the first 45 to 60 days before becoming adoptable. During this time, they will be under veterinary care and starting on their medications. This will allow us to adjust dosage if needed. Adopters will need to commit to continuing the treatment for 12 months. Adopters will be given instructions for care as well as an information packet for their veterinarian. An Adoption Manager will discuss everything with you once your application is approved.
