@luzmery928:
well I must admit Champ is becoming more aggresive with each day. But will also admit it is his parents (human parents)fault. We have not kept up with the training and have again grown lazy and minimized the walks. He bit me twice this weekend. Once for trying to take his bone away and again this morning for moving him in bed. I sopke to his trainer and he told me this is due to lack of training. He does not know who is in charge and we must go back to the basics and continue doing this especially since the home demographics have changed. Yes I admit to being at fault and will begin the routine again today!!!
Well….I don't know if it is due to a lack of training, that Champ is acting out aggressively...but training certainly could improve the situation.
I think that Champ may feel that his pack status is threatened by a new dog, and he is over-reacting when you assert yourself (taking a bone, or displacing him). I don't know that this means he has forgotten you are in charge...but more that he is hypersensitive to being required to do surrender status/power.
I would work on all basic obedience behaviors. I would make sure I am asking for cooperative behaviors before giving meals, treats or attention (sit for dinner, etc.) Most likely as things settle down, he will return to however he was before...but it is best to take a pro-active approach, and start reinforcing the behaviors you want to see.
