Hang in there. One thing to do anytime he hurts you is to *YELP*, just like you are another pup that he just hurt - you know how when dogs are playing and one "yelps" and it stops them dead in their tracks? That's what you need to do. You're saying, in his language, "ouch!!!! that hurt! you went too far, now leave me alone!". The book really IS good, a quick, easy read too!
