When starting to see Dr. Smith and Dr. Katie at CHAI, Dolly was not doing very well. I saw a huge improvement when changing her diet to limited ingredients and supplements. It gave her a much better quality of life and I am certain it also extended her life. We never had a bad visit, and everyone was so kind and welcoming, even if Dolly did not always see it that way!. She knew how to weasel out plenty of treats!
