I have a 7 month old newfoundland who is trying to be the alpha dog. When taking him out on the lead he will jump up and grasp your arm in his mouth and almost bite your arm. He also bites at your feet when you are out walking him. He is constantly challenging me for the alpha status. He will bark at me and bite my hand or arm. He is trying to be the dominant one all the time ...........is it because I am female.
I think Toby is a lovely dog but he needs to know he is not the alpha.
