I have a 13 week old yorkie who loves to bite. She does not nibble. When she bites she clamps down and won't let go. If I move the "target" she goes for another part of my body. Let's say she bites my hand. I move it, she then goes for my elbow. I move that she goes for my wrist and so on. I tried the following training techniques: the buzzer sound, saying ouch, a water bottle, distracting her with a toy, saying no biting, holding her snout .... I don't know what else to do. Please help
