We've taken in several 'biters', both fear biters from abuse, and a couple that play HARD. With 'Fang', he seemed to bite for attention, and always drew blood. I actually entertained the thought of renting him out for body piercing!The scruffing, hissing, dragging and time outs did not work on him. What I found was that he needed special time to 'learn' to play gently. I use a very light touch with him, both tickle games, and chase, and when he bit too hard, would just say 'no' softly, and continue to play with even more softness, cuddles n kisses where he couldn't nail me. It took a year, but no more blood! The other hard player just didn't know his own strength, and again, hissing, dragging, and scruffing did not work, probably because he wasn't exhibiting alpha behavior, so he didn't get it. More play time, and lots of 'no's', with cuddling n body massages when he's too worked up. Doing much better, no more blood Our 2 abused ones have been far more of a challenge, with Harmony being deaf... and a bit dim, but so loving except with playing! Tries to drag you into the tubes (makes it hard to pry her jaws off your finger!) Again, time, patience, loves, paw massages, and an eye to eye sign language 'no' (point finger at her mouth). She no longer draws blood, and is finally mouthing rather than biting down when playing with her humans! Little Beauty, teeth like needles! Insulinomic and adrenal, I do not know what had been done to these wee girls, but she was so fearful of being touched, or picked up, it's taken over a year for her to learn to relax in our arms. She will still do the tense and splay her hind legs when picked up, but relaxes now quickly. She no longer fear bites, but we did nothing special other than a lot of intense cuddling, nuzzling, and again massage. (and no, I'm not a massage therapist!!!) The best thing to do is to observe what is going on that precipitates the biting... play, aggression, agitation, or attention getting? I just re-read your post... who is he biting???? Humans or fellow ferts? That's a whole 'nother thing. I also noted that you got him from a female, and you are so not! It may be a real guy thing for him...... and again, special time, gentle time, and not trying to out-alpha him should work! I know it sucks when you have to play favorites for a bit, but if he figures out you're his 'friend and not competition', and to be with you is a pleasurable experience, it'll be worth it for the both of you! Hugs, and patience! Michelle and the 15 fuzz-butts [Posted in FML issue 4793]
