I assume you don’t free-feed so that your dog feels the need to guard his bowl.

Is your male’s bowl down all the time, even if it’s empty?

I feed three Rotties, two of whom (bitches) are ferocious with other dogs around their food. I feed all dogs outside (year round) out of eyesight of each other on three different sides of the house. As soon as they’re done eating, I pick up the bowls, wash them, and put them away.
