So over the weekend we had our first experience of some resource guarding. Over the past couple of weeks our 7mth puppy had shown signs of passive resource guarding which I had been keeping an eye on. When she had a toy/bone she had left around she would run and snatch it if she thought we were going to take it away, which of course we wouldn't. We never take her food away from her, or toys in the house. However, we have had to take bones off her that she has picked up numerous times when out walking. She never gives these up voluntarily, and tries to eat them as quickly as possible or clamps down very hard on them. No amount of chicken or anything will make her drop them. ANyway, last night she picked up some type of bone off the sidewalk and my husband didn't notice until he got home. She had been walking with it for about 3 blocks. Maggie would not drop it. He eventually opened her mouth with his hands and removed it but whist he was doing this, she snapped at him and drew blood. Obviously he shouldnt have removed it the way he did but what is the method to take things they shouldnt have off them? Does this one incident mean she is a 'resource guarder'? How do we go about preventing this again? Resource guarding is something I know very little about. Any help grateful. Thanks.
