I don't remember exactly how much, but it was alot. MAXIMUS was stung by a wasp one year. We saw the vet, got a shot, and he sent us home with 100mg caps. to take 1 or 2?, twice a day. I'm pretty sure it was 2, 2x a day....but then, he's about 90lbs, and it was an allergic reaction to wasps. Sorry. Telling you all of that probably doesn't help you.
