When my Bailey gets like this, the only thing I can get him to eat is the Gerber Chicken Sticks. He'll eat those even if he won't eat chicken. Have you tried Rebound? Its a liquid supplement for dogs recovering from surgery or just dogs who won't eat and need nutrition. This is the other thing that works as a last resort for my Bailey. He really loves it and it worked wonders for Lily. I get it at the vet's office.
I hope you find something that works.
