Yes, Sue, I think this just may be the thing that's making dear Killi so miserable. I can't wait to hear what the vet says. I wonder why no one else ever thought of it! And with his liver compromised, it so much harder for him to fight it own his own Please, give him a big hug for me Sue. Jackie, you're pretty quick on the keyboard yourself!! And, as great minds think alike, we both went to the same vet site!! Give those crazy Schnauzer kids a big hug too!
