quite a few years ago a friend's GSD developed demodectic mange, the vet
they were going to treated her with the injectable cattle ivermectin -- i
don't know if he injected it, gave it by mouth or what.

i'd be real tempted to asked the vet about a diluted solution to be rubbed
on the spots.

i don't know what breed duffel is? if a collie i wouldn't use it unless
under vets advise.

have used a drop or two in barn cats ears when they had ear mites, only
takes one treatment and they are all gone. upon advise of the head
caretaker of the lab animals at a university i've also wormed the barn cats
with 2 or 3 drops orally.

my vet here does mix up solution of ivermectin for clients such as myself
with multiple dogs to give orally for heart worm, i just did all of mine (1
ES, 3 collies and 2 BC) for the first time with no problems with any of
them.  she suggested i do the first time on days when she was to be in the
office, giving it in the early a.m., in case of any reaction.  so now i'm
good to go every month with it.
