I've been working on this for months and my poor dogs are just getting worse. I'm sure that it's sarcoptic mange mites because it has spread onto all 4 of my dogs, some are more effected than others. I'm going to see a vet in a few days, but I'm economically challenged and I've tried every home remedy imaginable, baby oil, mineral oil, cooking oil, Mule Team Borax + hydrogen peroxide dips, lime-sulpher dips, pour on ivermectin and more. Nothing has worked. I think I want to try an injection of ivermectin. Does anyone know if/where I can get injectable ivermectin over the counter?
