Two pieces of advice that are almost treated as gospel on a mini forum that I regularly visit:
Don't use Bute on minis. The margin for error is very small, it is too easy to overdose a mini with Bute and give it ulcers (which can happen even at the correct dose, too).
Don't use Quest wormer on minis. There are lots of folks who will tell you, "I've used Quest on my minis many times with no problems," but once again, the margin for error is very small, many people overestimate a mini's weight, and overdosing with this product can kill a mini outright. Better to be safe and sure than sorry!
