Hi! We brought home our first goats yesterday. We have three ND does. Two of their coats look rough. It could be genetics, as these two are mother/daughter, but they do seem to be scratching a lot. I do not see any lice, but they do have some dandruff. I am wondering if they have mites and wanted to go ahead and give them an invermectin injection and use some Python dust. Also planning to copper bolus soon. My local TSC carries the Durvet Ivermectin Injection 1% Sterile Solution, 50 ml, but this is advertised for cattle and swine. Is this okay for the goats? I have read where most people dose 3ccs per 25lb of goat--would this dosage be accurate for the Durvet Ivermectin?
