Is it okay for a 6 week old puppy to play with 2 older dogs?

a 6 week old puppy? he's way to young for grown dogs. unless he is under STRICT supervision at ALL times by you. the other dogs, not meaning bad, can get WAY to rough for a puppy that young. you'll have to keep your eyes on him constantly or you could wind up with a dead puppy. i'm sorry to say that, but he's too small and too young to be left alone with grown dogs. yes they will teach him the "dog things" he needs to know just be VERY careful. the vaccs. thing is good. congrats! he's going to need a few more vaccs. before it's safe to let him play with other dogs. but due to his small size just be VERY careful. although your older dogs may possibly amaze you and turn into "nurturing" parents, just make sure you are there the whole time they are togather, for his safety.
