“I use Revolt because it has osinly one ingredient, selamectin, the topical form of ivermectin. Products with many ingredients usually mean they will cause seizures or sometimes liver problems. If you need to just have a product that protects your dog against HW infection and kills fleas, this is it.”
“So far so good. My dog stopped eating the flea and heart worm meds. This resolved that issue. Easy to apply. The cost is why I am not giving it a higher review.”
