So I am taking Bernie to a handling class, and the school is requiring up to date shots. Bernie received his complete set of shots when he was a puppy but because of the over vaccination information I have been reading I did not do any yearly boosters besides the rabies which is required by law. Is there any way around this? I really do not feel like pumping Bernie with the 4-1 again, I will get the bordatella but I don't want to give him that 4-5 or 5-1. I was also considering the titer test but I don't know how long it takes, I am going to start the class on Saturday. Any help will be greatly apreciated...
