Assume an adult human weighs 120 lbs. (Would like to weigh that again, myself) If the dog weighs half that, it gets half a dose. Actually, with probiotics, it doesn’t matter if you over do it, especially for the first few days. I would give one whole capsule each day for a week or two, then give one capsule every other day. When everything is back to normal, twice a week is enough.
