We have a line of dogs with it - Zimectrin Gold daily will clear it up. I use one dial turn per 20 lbs daily or you can use liquid Ivomec .10 per 10 lbs daily.
do u give the zimectrin gold everyday for the rest of their life? and the ivomec, i've heard in the past that too much ivomec will kill a dog. we've been to vet and done the dips and apparently they didn't help because it was back within 4 months.
