Also, be aware - the capsules don't usually work nearly as well for many dogs as the powder does on the actual food.
Check out enzyme diane (google). Much better pricing, fast shipping; a lot of us have used her for years. My GSD was DX'd with EPI when she was 3 yrs, and a couple months old. It hit hard and fast. I only used the vet enzymes for a short time until I found out about enzyme diane and have used her ever since. My girl is 8 1/2 yrs old now.
