Hogan has what I think is mange, caught from his field mate (who has it really bad). I've used the lime plus dip, which the vet gave us for lice, and is supposed to work on mange too, but it's not working that well. I see that ivermectin is recommended, in wormer form - has anyone tried this, and what was the result? This is the field mate, Hogans nowhere near as bad - yet. The vets given a shampoo for field mate, but there's not a massive improvement.
