Q. What happens when a lyme positive dog gets a lyme vaccine? Jasmine, a large Pit Bull, seems lethargic and is lame in one of her legs since the shot
A. It is controversial whether to vaccinate dogs for Lyme disease that have already been exposed. Some vets feel vaccinating an already Lyme positive dog will decrease the duration and severity of any future Lyme flare ups. Any vaccine carries with it the risk of the development of minor clinical signs which are usually temporary. The symptoms you are seeing may be related to the injection or to the prior Lyme infection. If she is showing clinical signs, she should be examined by your vet and treated as indicated.
