Canada has a long-standing requirement for rabies vaccination of most categories of dogs and cats being imported from countries not considered free of non-bat rabies.  While this requirement helps protect dogs and cats from rabies infection should they be exposed to endemic wildlife rabies that is present in Canada, it does little to prevent rabies

A recent publication in the Journal of Veterinary Diagnostic Investigation (Haydock et al. 2022) describes an interesting but unfortunate case of tuberculosis in a dog. Published reports of rare cases like this are often of limited value, but sometimes they highlight important broader issues, and I think this one fits that category.
