Hello, I've got a herding breed puppy. She's 16 weeks old and for the last month or so, she's been snarling, nipping at the backs of my legs and jumping up and biting at my hands and coat on walks. Sometimes it's at the start of the walk, sometimes the middle or end, often it's for the whole time we're out. I wondered if it was over stimulation but we've just been isolating for 10 days and she was back to it immediately today! I've tried stopping, making her sit, turning my back, ignoring her, giving her a toy etc. but nothing works. As soon as we start to walk it begins again.
The bites hurt, she's ripped the back of my coat to shreds and it's getting annoying now - any idea on what I could do to stop it happening or is it just a phase that will pass?
Is it a herding thing? I always know when it's going to start because she either nips the backs of my legs or runs round the front of me and stops. Should I be doing something differently when we're out? Is she bored?
Help!
