How many pills depends on the size of the pill ;) If it's the bulk pills from Sam's/Costco, that's 150mg pills. That's a dosage of 22 pills each feeding for Gus. But those are small, and when I used them, I just threw them in the feed (soaked a-pellets) and they were eaten right up.
If I did the calculations right, Gus is 500kg. So that's 6.6mg (times) 500kg, which would equal 3300mg/dose. Right? If so, that's a lot - or seems like a lot. So how many pills would that be?
Vet may be totally unaware of the Day 14 (Day 1 is first dose) issue with the ulcers ;) If there is going to be an issue, it's not very likely to happen during the 5 days of the PP. It can, just not likely.
JB, I wouldn't mind trying Quest (despite all the negative reviews I've heard on here) but... Gus is still a bit underweight and I wouldn't want something to happen to him because of that. I'll just keep an eye on him to make sure nothing gets worse... if so, I'll just discontinue the PP. FWIW, vet did okay doing a PP.
