I have 3 indoor dogs, 4 indoor cats, 1 outdoor dog, and for now, 4 outdoor cats. Obviously, medical expenses could get quite high just with prevenative care. So, I get revolution from the vet, and the dogs rabies shots every year. But, the vaccines I get at TSC and give to the animals myself----I was just wondering if anyone else on here uses them and if anyone on here has reasons NOT to use them. I have worked for a vet in the past, and know how to give the different injections-----but I was also told by my vet not to do the first series of shots (for puppies/kittens) with the ones from TSC because they are generic and may not have the exact amount of what is needed. But they also said the ones from TSC are fine for a yearly booster.
