I had good results with IVD rabbit also.

Jes talked about making treats. I did that with the IVD rabbit. I put the kibble in a blender to grind & added the canned food. I also put in cooked sweet potato at the suggestion of my derm vet. Mix until it is the consistency of cookie dough, form into little cookies & bake at a low heat until hard. I think I baked it at 250 degrees.

If you're really nuts (like me) you can get a food dehydrator & make your own sweet potato jerky or just dry out the dog cookies.
