As some of you know we got a new male puppy a few weeks ago and he is doing wonderful as far as playing and doing well with the kids. My problem is, at times he seems like he would be really agressive, for instance, my dad was playing with him and "wooling" him, which he was coming back for more, but while he was "playing" he was also growling and it just sounded really fierce and not like play growling. It was like he was really mad. Then yesterday he had went out to potty and got some poop stuck on his hiney in his fur, so I had to bring him in and wash his butt and when I would take ahold of his tail to lift it up to wash under it, he turned around to me and growled sortof and snapped at my hand. I really do not want this to be a problem and he is only 11 weeks old. So I guess what I am asking is, is this something to be worried about or what do I need to do to correct it before it gets out of control?? He has never acted this way any other time. He gets along with Ciera (when she will let him..LOL) and he has never snapped at the kids or anything or even barked at anyone strange for that matter. So I am confused
