well i was wondering if this may be a bad thing. I always play with rambo with my hands, i shove my hand in his face and tap his nose and push him around, when i start to push him away from my hand he starts growling a lot. When he does get a hold of my hand he just nibbles, never bites of hurts me. Any time while playing i put my fist up (to sit) he stops right away and sits. Everything seems great but my room mates are worried. One time we where playing in the backyard (when i first got him) and he started growling, their husky didn't like this and when he nipped rambo in butt, he lit him up (kind of surprised b/c they get along so well, and the huskies 90lbs+). So im assuming he was in aggressive mode when he attacked. To be honest he's a bit of a sissy. He's normally always the one getting attacked and beat up at the dog park. Anyway im just trying to figure out if i should stop it immediately? He's 7 months old.
