I adopted a possibly 2 year old IRN. I was told she was a female and given up because of nipping. She loved me at first site. She would head roll when I spoke to her, held her , she loved me and still does. After the first day the “nipping” started. I could see why someone might re-home her. It was a very hard almost blood drawing bite. I spent 2 months making friends and now I don’t have an issue. My trick was offering her an almond, she would head roll. I called step up and then I would move her. Of course it was a little more than that but my question is.. Was that a unresolved bluffing issue? Just your best guess is ok.. Thank you for your time.
