I have a 9 week old Sheepadoodle who grabs our pants when we are trying to walk and proceeds to try to play tug of war with our bodies despite us letting out a sharp Yelp, freezing turning our backs to her and crossing our arms. She just seems to grab stronger hold sometimes pinches our skin. She doesn’t respond to redirection with a toy. we essentially pry our clothes out of her mouth or pick her up. She is a very kind smart girl when she is not wild like this, but she can turn into a stinker very quickly. Please advise how we can stop this behaviour.
