Leptospirosis is a bacterial disease spread in the urine of infected wildlife including deer, skunks, raccoons, moles and voles. Dogs may become infected by licking the urine of infected animals off the grass or soil, or by drinking from a contaminated puddle. There have even been reports of “house dogs” contracting Leptospirosis from contacting the urine of infected mice that have entered the house. Bogue Animal Hospital recommends annual vaccination to keep your dog safe from this serious disease.
