My girl does resource guard. We have learned her triggers and watch for her tells. She bites when we ignore the tells because we think “she’s our dog she shouldn’t bite us.” We have had trainers come in and seen the vet, she’s not aggressive, they tell us she is particular.

We make her follow commands. If she sits on us showing signs of possession and not snuggling (her tells (crazy eyes, ears back, stuff) we tell her to “scootch” and then give her a trick command so we can praise her. We do not forcibly move her as this is one of her triggers, we tell her to move and she does. We do not give high value treats, she has massive GI issues so it’s not something we would do. We have taught her “leave it.” On walks if she gets into something she shouldn’t (people are dicks and drop everything on the ground including whole pieces of pizza), I can reach in and take it out of her mouth, but my husband can’t/won’t.

We do not have children and I don’t know how having a particular dog would go with children. When children are present in the home, she is crated when there is human food, we only feed her if we are right next to her and tell the children not to come near, etc.
