Our new dog wich we rescued is a bit ruff taking snacks out of your hand. She gets all excited but grabs it real hard and fast. She doesn't chomp your hand or fingers. But it can smart. I held on to the snack and was trying to tell her easy as she took it but I guess she really wanted the dried jerkey. I held a piece in my hand and she still grabed my finger with it and it was not a small piece. Is she affraid she wont get any or the other dogs will get it or is it because she was on the roads a while and affraid the snack will disapear? I don't want to yell at her but I want her to take the food easy and leave the fingers in one piece. any advice would be appreciated.
