My vet suggested me to bring my pup to the puppy school, she said its important to get my pup to socialize with other pups. She said I should wait til the 2nd vaccination before joining the puppy school at the start, but becos of some sort of timing problem, they now asked me to join before the 2nd vaccination, they said it is fine to do so. And the puppy school is actually for free, so i understand the fact that they are not just trying to make money from it. Some people been telling me I shouldn't bring my pup out to interact with other pups before the 3rd vaccination. So I am now confused, I don't know should I bring him to the puppy school, or should I wait. What do you guys reckon??
