My Flynn is usually a good boy. He's 10 1/2 weeks and chews everything which we are getting resolved with toys so that's getting better. But he has taken to biting me (and only me) until I bleed! It's usually in our playtime he'll put down his toy and come and bite me if I say no and move my hands away he backs up and lunges at me! I think he is just playing rough which is something he does with me and no one else I also think he is bored (2 1/2 weeks until he can go outside) but what can I do? I think he sees me as the 'leader' as I am here all day, feed, teach, play etc and my mum thinks he might be testing his dominance but any suggestions on how I should counter this? I want to point out this is only for a short time a few times a day he does this but it's enough for my hands to have a good few cuts on them! The rest of the time he is clever, cuddly and sweet! Sorry for the long post, it's not a huge problem but I want to nip it in the bud now so it doesn't develop into an aggression problem with age!
