I had a husky-lab mix. He was not food-motivated at all. We did _not_ leave food for him all day long, because the other doggo, purebred lab, would eat the food designated for the husky if we did.

So we fed them both at the same time, twice a day, and had to watch if the husky would eat or not for that meal, and remove the food bowl if he wasn't hungry, so the lab wouldn't scarf it down.

This is an n=1 anecdote that your guess was the opposite of my experience. That dog just didn't care about food. He did however love eating ice cubes. I never tried just a bowl of ice cubes.
