I have a 5mo. old female boxer/lab mix and she use to not bark. Lately she has been getting a mouth on her and anytime I tell her no she starts barking at me and tries to bite me. She thinks I am playing and I have tried everything from putting her in time out. Spanking her, holding her mouth shut and telling her no bite and she just keeps barking at me and biting more. I just don't know what to do besides get a shock collar or pinch collar. We currently live in an apt. and I am afraid if we don't do something soon the neighbors are goingto start complaining. HELP!
Is this what you are talking about? Can I ask you why you bought a muzzle to train your dog with? What kind of training are you expecting to do with this muzzle? I'm sorry but I have never heard of using a muzzle to train a dog with so is it some type of training beyond basic obedience training ?
