Hi Kellye P,
Sorry for the delay in getting back to you.
I’ve been thinking about the Ketones in his urine and what would cause that other than high blood sugars. Ketones are a sign that his body is looking for alternate sources of energy and he is starting to use stored fat as an energy source. It points to a problem in getting energy the usual way which is through his diet. Canine Exocrine Pancreatic Insufficiency (EPI) is when the pancreas no longer produces enough digestive enzymes to break down his food into usable energy. This could be why he throws up if he eats foods high in fat or if he eats more than you are feeding him now. It could also be responsible for his weight loss.
Treatment for EPI includes replacing lost pancreatic enzymes. The types and amounts of enzymes needed would be different from the enzymes you are giving him now. I would think about trying the enzymes because it would be a pretty low risk solution if it works. I would also start slowly and get up to the full recommended dose for him over a couple of weeks to see how they are affecting him and to minimize any side effects. This is a link to a place where they sell the types of enzymes you would need without a prescription and at a decent price:

I would order a small amount of the 8X version to try out. Here is a link to an overview of how to use enzymes for EPI:

And lastly here is a link to an overview of canine EPI. There is a lot of useful info on this website:

Good luck and please keep us updated. We all are hoping for the best for you and your little guy!!!
