It's really wearing me down, being constantly bitten. Puppy is about 11 weeks now but he always goes to bite. He's your average amount of bitey during the day but on an evening when all I want to do is sit and relax he goes mental and becomes quite aggressive. He has a variety of toys that I alternate, I will play tug of war with him while I'm sitting but then he starts lunging and will not give up. I'm trying hard to be really positive with him but I just can't take this biting of me and the children.
