Moxie and Decker will not eat the plain non-fat yogurt the vet told me to feed them. It's only a little bit each day but they refuse to eat it and Moxie squints and runs from it. Is there something I could use to flavor it that won't make their diarrhea worse? Moxie won't eat can food so that is no use. Any suggestions? They are suppose to be on a bland diet, very low fat.

Thanks in advance.
