Chagas disease in dogs

Chagas disease in dogs is caused by the parasite Trypanosoma cruzi, transmitted mainly through contact with infected triatomine bugs (also called kissing bugs). The parasite enters the dog’s bloodstream, often affecting the heart and other organs. Some dogs show no symptoms, while others may experience weakness, weight loss, coughing, or signs of heart failure. It can be diagnosed with blood tests and treated with medications, but early detection improves outcomes. Preventing exposure to bugs and their habitats is key to reducing risk. Chagas is a serious condition that requires veterinary attention.
