so finally today we had FUN! we went to the park at a different time and there were new dogs we never met before.. and jacob had so much fun and played well with everyone (which makes me think the 'behaviourist idea' is crap... just bad luck and bad dogs etc) anyway he played with one basenji and pit x named Corona, and loved each other. a Husky girl and a little wired hair Jack Russel. i am feeeling better now that he played with normal dogs and no injuries!!
