I never took Bella (my dog/avatar) to any classes. But she grew up with 6 tiny dogs and is very well mannered. Def take him to parks and get him used to being off the leash (if he is able to be let off) with other doggies.

I go to a nice park in d-wood area and I walk in I get a lot of nasty stares but I let Bella loose and she has a blast...until the male dogs try to hump her. She's one hot piece of ass. lolol
