Sorry I've been gone for awhile. Just wanted to give a final update. Murphy has not had diarreha/vomitting/etc. since the switch from Nutro. Scary that this food could cause such a reaction in a dog. Murphy is more hyper than ever too! We always thought he was just lazy but nope. He's a whole new dog now that he's not eating the Nutro brand food. Yay for Yorkie talk. You saved me $52 for the vet test and saved my puppy from being sick any longer

THANK YOU ALL!
