  • The bacterium that causes Lyme disease can be transmitted to dogs through the bite of an infected tick, most commonly the deer tick (black-legged tick), which is found in the midwestern and eastern United States and throughout Canada. The disease typically causes pain and swelling in the affected dog's joints along with decreased appetite and fever. The kidneys are sometimes affected, in which case the disease is often fatal. Diagnostic testing, treatment, and ways to prevent Lyme disease in your dog, including instructions for tick removal, are explained in this handout.
