Puppy advice please ? ?

You should NOT be teaching your dog to fetch, or play frisbee. The pup is too young, and you are going to damage his bones and joints. Also, teaching a dog to fetch encourages obsessive behavior, something you don't want to encourage. The breeder should have answered all of your questions prior to taking the pup home. The breeder is there is answer any additional questions that come up. You need to supervise the dogs when feeding. Unless the pup has had it's entire course of vaccinations, you shouldn't be taking it out in public.
