If you join the K9-EPIGLOBAL yahoo group you can order the enzymes for much less that any where else as well as get a lot of good information from ther owners of dogs with these problems. Your vet can also contact TX A&M for lots of good help as they are doing major studies on animals with these problems. Also have your vet check the B12 levels that cause SIBO as the treatment is a little different. You need to feed a low fat,no grain food- Dick Van Patten Limited ingredient foods are good. It does take a while to get things to settle down but can be controlled. Noelle, my whippet, is doing very well now that I've fount the EPI group and most people don't realize she has a problem. Good luck.
