Dog won't eat out of his food dish unless he's really hungry. I thought he wasn't eating every day because of the season but I may be wrong. If I put his worms in his food dish, he'll look at them for a minute and walk away. The worms will dry up and be wasted.
If I put the worms in front of him on the dirt or further away in the dirt, he'll run right to them and chow down. I guess he prefers to 'hunt'. It's funny watching him because it almost looks like he's trying to stay out of view and then pounce
