Thank you Brister for your reply.
I returned the unused can of Natural Balance to the Nutrition Pet Store in my area and purchased a can of Canidae and hoped all the way home that Toby would like it. I talked to him, while I opened the can, and told him this brand is really good for you. I put the bowl in front of him and he gobbled it up in a split second. My search is over and my dog is happy.
