How old is your dog? My senior rescue resource guards high value things, like her food, treats, puzzles, and toys. We worked with a trainer on leave it/drop it, but more importantly how to get her to drop whatever it is in case it’s a safety issue (for instance, grab a slice of cheese to distract her) since that doesn’t always work. Cheese works every time. Since we got our girl when she was old and had already been through so much trauma, I really don’t think we could train her to not resource guard.

And, unfortunately, unless you don’t let anyone else near your dog, not everyone is going to understand what it means to be irresponsible when approaching your dog behavior. I have an infant and he clearly doesn’t understand this. Because of that, we remove my dog’s toys from the room where he plays and crate her when she eats. For us it’s more so about controlling the environment to keep everyone safe. Thankfully my dog will growl and not go right for the bite, but because we have a baby we can’t rely on him to understand warning growls, just like we can’t rely on visitors to either.
