I've had my little Franklin for about 4 months now. He gets a little red zone sometimes when we tell him "no" or just now when I started brushing him. He turns from this sweet loving pup and he will bite my hands and bark and growl. 

So far the way I've dealt with it is by saying "No bite", I grab his bottom jaw and will give him a time-out in a bathroom. When I got him back out today he seemed really sad and we had a little chat and made-up, I guess I just worry that not all…
