Hey Blinky, I posted the story in its own thread cause it wasn't really an "ask the trainer type of deal" but to make a long story short, we met my puppies older sister last night (6 months older). It was kind of a view into the future. His sister was very dog aggressive. She attempted to attack McBain but her owner restrained her. He blames it on the breeder and the fact that their dad was very aggressive. If this is true and it is bred into him, what can I do to not have this be an issue for McBain? I figure proper socialization is key so I decided that I will stay in this class so that he can be around other puppies and get as much socialization as he can. Do you have any other recommendations? Thanks Blinky.
