We've had our greyhound for about a month and he's been great except for one problem- he has resource guarding issues. The first time we saw this was with a femur bone that we gave him. He growled when we tried to take it away and again when I just tried to pet him. He's done it a few times with toys, but only if they're new and it's mostly about bones. He has snapped at my fiance once (small scratch on the hand but the skin wasn't broken) and twice at me (hand and arm but no broken skin or damage). These episodes are very frustrating for everyone, and after reading here about trading up I know that we moved too fast with his training on this. He was doing well with toys, but I'm having trouble finding something between a toy and a bone as far as value. Also, if he growls and I step back and let him have the bone, isn't that reinforcing the idea that he can growl at us to get his way? I just bought the book "Mine" about this issue and plan to go through the steps. I am really just posting here to get support and see if anyone has a happy ending to their dog's resource guarding. Feeling frustrated I should point out that he doesn't have a problem at all with his normal food. We can take the bowl away and put it back down again while he's eating. He also doesn't seem to be space aggressive at all. It's just the high-value toys and treats that are the problem. I know I can just not give him bones, and that's the plan for now, but I want to be able to take anything away from him in case he ever gets into something he shouldn't. Thanks for reading.
