A. I would be headed back to the vet. Only eating chicken soup is not an option, long term. I am sure his mouth is quite painful so hard kibble may not be an option right now but I would try getting him to eat something more nutritious. Soak his regular kibble or make him something easier to eat like boiled chicken or ground beef with rice. I hope you were able to find the cause of the blisters and hopefully with medication they will clear up soon.
