Just discovered a bad case of what looks like mites on the front legs of one of my bucks (crusty thick skin coming off with the hair, no sign of any sort of infection). I’m not sure how I missed it, but I feel awful it is this bad (have never dealt with them before). I’ve picked a lot of the scabs off (as much as he would tolerate) and coated all the areas with NuStock. I’m having my husband pick up SQ ivermectin and plan on giving him 1 mL/40# body weight x 3 doses every 7 days. Do I need to do pour on ivermectin as well? Should I treat all the bucks?
