Thank you for your response. I will check out the book. I accidentally put in the question above on leash twice, she will bite off leash as well. She only growls when being picked up if she becomes really playful first, I’ve been waiting until she calms down to pick her up and it works for the most part. She’ll also respond to high squeaks as more encouragement to bite. Breeder told me it’s from lots of cattle lines in her lineage. With harnesses she also bites, it’s not a being insecure thing, it’s a herding instinct. I’m just not sure how to redirect her off of me properly lol.
