Ok, this is only in my opinion. My two dog's only got their puppy shot's which were around $100 all together per puppy. After that, we no longer took them for their shots. Only because it is proven that dogs get more sick after all those unnecessary shot's. My 5 year old Pitbull has NEVER had any medical problems, and my 3 year old either. As for my fiance's 6 year old Rotti she got all her shot's, spent maybe night's/week and month's at the vet, we lost her last year. Dog's don't need a "flu" shot lol..I think that's just stupid and another way for the government to make more money.
