I will definitely be doing titers from now on..No more shots for Chumley... He just recently had a 3 yr rabies shot which was mistakenly given by the vet. He wasn't due until 2015..Since then he's had allergic reactions, inflamed red bumps, itching, and head tremors. The vet claims its not related but his problems started after the shot..I will never get him another rabies shot again..no matter what the law is.
