Hello, I have a viszla called milo he is now 7 months old. I’m the one who’s always takes him out and the main one who’s there to feed etc as my parter is always out the house before me. Ever since we had milo he has always jumped up trying to bite me I have always put this down to playing till recently. He keeps trying jump up and bite me and won’t let me take him for a walk he will either try bite me or my coat or the lead to make it very difficult for me to even walk down the street with him. I carry treat to try stop him from doing this but it doesn’t work. I’m not sure why he only does this to me and not my partner. Can anyone help me please?
