why does my dog who is now 12 mths old, and not teething anymore, nibble on my chin or my fingers? he used to do that when i lay in bed, in the morning, but now he even does it anytime he wants to. does that mean, he shows me affection? or is it a sign of dominance? i mean is he trying me? when he does that he puts both his frontpaws on me. and kinda pins me down.hes usually very submissive, and sees me as the alpha. maybe i should mention that he lies with us in bed.heehee.which some people don't tolerate, but it doesn't bother us. should we change that? an make him lie on his own pillow/bed? but i guess it does not mater, because when he wakes up, he wakes me up biting, well nibbling. today i was sitting on the couch, and he nibbled me in the side. i would appreciate any input. now it's starting to bother me. i didnt mind him doing it with my hand, but now it's in different places of my body. iwas joking and told my husband, maybe he thinks i'm a bone, cus i'm so skinny.lol he nibbles on me, like he would on a bone. please help!!
