Hey guys, I see a lot of threads about resource guarding, but I feel my situation is a little unique, so I apologize if this has been asked before.
He's the only dog, eats extremely gently from my hands, and is fixed. I can put my hand in his food bowl while he's eating no problem, but in the last week he has growled at me when he had high value treats and I got close. He's not snapping or snarling, it's just a low growl and he postures defensively. Each time I was able to take the treat without incident before giving it back to him. I'm trying to head this off before it becomes a more serious issue.
