It is not because your female is unaltered (he is too young to make that distinction)
When the pup grabs your girl, are you saying she doesn't try to stop him?
It does have to do with his energy level, and her not telling him to stop.
When she runs from him... he wins... so to speak in the dominance game.
You can tug his neck hair gently(a little jerk) and say no, when he is misbehaving with her. And if he plays too rough with the people, a firm "NO" like you are doing, and set him on the floor. (IGNORE, for several minutes).
Fo rthe energy he has, play with him, throw a toy, NO TUG OF WAR!!! Go for a walk, even around the house. Absolutely no rough housing, or dog noises at him, until he learns to respect the people, and learns his place in the family.
I am sure you can do it! Be ULTRA CONSISTENT!!! Set him down, and turn your back for every mis placed nip! His growling may be just noise, but show that you won't have it, if you don't want it. |
