My 4 years old male Welsh Corgi has had this problem where he very often does not eat unless accompanied. We keep him in the backyard, and as soon as I leave him and close the glass door, he ceases eating. When I or someone he recognizes comes through the door and stays with him, he immediately starts eating.
There have been times when we placed food in his bowl and he doesn't eat until the next morning, when I come through the door to play with him.
Any thoughts or help would be great.
