I hope he does well with the Pure Vita. Pumpkin never really worked that great for my pups. Surprisingly, unsweetened applesauce was better. I think because it contains pectin. Check out http://www.dogaware.com. It has a lot of helpful info on digestive disorders in dogs. I would try to add just one new thing at a time so you know what is helping and what isn’t.
My dogs had both giardia and coccidia when they were young and it took some time to get them back on track when we finally got rid of all their bugs. You could at least rule them out with a fecal so you won’t be switching up food and supplements for no reason like I did for a long time. Please report back on your progress!
