Little Aldo is now 14 weeks old and doing pretty well for the most part. His biting on things has eased up when around me or my wife, but is relentless for some reason when around our 13 year old son. I think initially he was not giving the dog enough positive attention and now the dog has learned to get it by any means necessary. We talked with our son about making sure that he is enthusiastic when dealing with the dog, and shows in his body language that he is not afraid of getting bit, but Aldo is not giving in. He has tried putting the dog on his back and holding him down until he is calm, but then as soon as he lets him up, he is right back into attack mode. Any suggestions on how to deal with this would be appreciated - this dog was supposed to be the son's buddy and he is not bonding positively for some reason...he is getting frustrated because the dog just wants to attack him.
