Canine distemper originated in North American domestic dogs in the late 1800s. Ever since, this deadly family of viruses has spread like wildfire through wild foxes, wolves, coyotes— and even unrelated animals like lions, bears, skunks, and raccoons. Many animals, like the Ethiopian wolf and Amur leopard, are now facing imminent extinction due to distemper and other domestic-origin viruses. These conditions can spread from a pet to a wild animal if the wild animal sniffs your pup’s pee— no direct contact required! You can do your part to protect wildlife (and your dog!) by getting your dog all vaccines and boosters recommended by your veterinarian.
