Ivermectin is a medication used on dogs for heart worms. My dogs have decided that possum hunting with an occasional coon thrown in is their new hobby. I noticed two days ago, that they are scratching like crazy with a spot of hair missing. I put Bio-Spot on them for the fleas and ticks. I dosed them again with the Bio-Spot, but the itch is still there. I read where Eprinex kills mange mites on cattle. I have put pour on Ivermectin on dogs before without any problems. I wonder if anyone has ever used the Eprinex for mange mites on dogs. I think the coon that they got the other day gave them something that they could remember him by. Anyone out there had any luck with this procedure?
