I use the Safe-guard liquid for Goats! It works well and the 4.2 fl oz is only 16.95 at TSC. A very good friend in the agricultural business put me on to this. My vet says it's the same. The directions are on the back of the bottle. They suggest for 125lbs use 2.9ml. So for a 250lb mini I would use 5.8ml per day. Hope I helped
