puppy pre school is basically just for socialising and getting out and about while the puppies are young ( I took my jack russell to puppy pre school cause she was too young to go to the park, 12 weeks and under) I'd still take him to puppy pre school, then a few basic obedience courses! my dog still bites (she's 1 now) but that's cause I rev her up and play, she knows its ok until I say "friends" and she stops, haha.
