Well we went to the vet today and he wants to put both dogs on a grain-free, single protien diet. He was on board with Pinnacle however, it isn't sold anywhere around me. I mean no one carries it and it would have taken several days to get it.
So we went with plan B. We are now on Timberwolf Organic - Ocean Blue. A completely fish based meat and grain-free. I have never had any of my dogs totally love dog food, but when they took one whif of this very stinky stuff, they seemed to love it.
So we are now treating Zekie with medication for an extended period of time and pray that the symptoms are managed and he can live a comfortable life.
Thanks to all for your very valuable advice and experience.
