A.We have been very successful with these cases. We use Acetylator by VetriScience. It does have a glucosamine derivative in it but it may be worth trying. We also use a homeopathic combination of BHI Intestine and Diarrhea. I’ve just started to work with a new product called Primal Defence (homeostatic soil organisms) which I feel will have great benefit. As for diet, I list a potato diet in my book similar to that you are currently feeding, but with a few additions. In all these cases we perform a metabolic analysis to align the other organs of digestion and assimilation.
