I feel your pain. Mine are pickey pups! I found a food that mine love. I do feed kibble daily, but I feed this every other day. They will fight for it! Check it out, it comes in beef or chicken. I buy an 8 lb roll for $10, with my 4 it doesn't last all that long, but it is a great food. I guarantee this will get eaten. It is available in our local Winn Dixie grocery store. If you have access to it, you should definitely try it.
