Aggressive Minature Pinscher Puppy

by Jen
(Glen Burnie, MD)

I have a 4 month old female minature pinscher. When I try to take things away from her she is not suppose to have or if I move her when she is sleeping or laying down she will growl and sometime try and bite us.

I have tried pinning her down, growling back at her, telling her no and scruffing the back of her neck. She will stop but will also continue the behavior the next time we try to make her do something or take something from her. She does not do it everytime but it is becoming a daily habit.

We also have a male minature pinscher and a mutt. They are both males. She plays rough with them but if she gets out of hand they put her in her place. What can I do? Please help
