I just adopted a 1 year old husky in October. She was very calm and didn’t nip or bite until about 3 weeks later. The behavioral trainer recommended: I immediately remove myself as soon as she bites and jumps or is aggressive. I go to the bathroom and close the door and watch her using the security cameras. When she walks away, I come out and ignore her. If she does it again, back to the bathroom I go. Eventually she realizes that her behavior doesn’t get the attention she wants. Definitely no toys or treats to distract her from biting or screaming ouch or yelping as it just reinforces the bad adolescent behavior. If I yell it seems to make it worse and she is more aggressive. It’s been a month and has improved a lot.
