The San Antonio Humane Society says that in the last nine months, it has encountered three potential cases of Chagas disease in dogs. The triatomine bug, also known as the "kissing bug," transmits the Trypanosoma cruzi parasite to humans and dogs, causing severe illness that may lead to death. There haven't been any human cases in Texas, but the disease has been seen in dogs, and Texas A&M University is conducting a study of the extent of the kissing bugs' presence in the U.S.
