Thank you everyone for the tips. The biting is not aggressive it is playing but it hurts and he has left marks on me. I believe the biting is for attention which is what I understand he lacked in his first home. I have purchased a sonic egg on a suggestion of a co-worker. We have had the sonic egg for 2 days and used it 4 times and you would not believe the difference just getting his attention with a firm NO and pushing the egg while he is biting and he stops. I know this may be a slow process which is fine I just need to stop the biting and getting crazy at night. The last couple of nights he has been so good but he was so exhausted staying out of the crate all day so tonight will be when I know if the sonic egg will work on him. Wish me luck!
