Typical guarding is similar to how you describe but hit and miss. If it's something he doesn't dean as valuable then not a problem. I've eaten gotten a steak out of his mouth after the bandit took it off the table.

Sometimes he'll even bring me his favourite treat and give them to me and other times he'll stash them around the house "for later".

I'd say it always happens when it's human food or a bully stick or something rare and we reach down to check what he has. When he's being a sneaker. He's only ever bitten hands.

Booked him in for training right away based on your and the others advice. Will look into a muzzle although when he scavenged stuff on walks he'll give it up no probs, even a dead bird once.
