Muzzles are just mouth chastity cages.
Hounds that always stay muzzled will be starved for feeling against their lips, tongue and teeth.
Feeding would be one of the only times a hound is allowed to experience feeling in and around their mouths, which would make eating out of a dog bowl all the more gratifying, regardless of the quality of the food.
Not to mention the ecstasy of being allowed to put it's lips and tongue to hard leather as it polishes Her boots, you have to imagine that would simply feel like heaven.
