Did the vet do a scraping and confirm live mites? There are allergies (especially food allergies) that can give the same symptoms as sarcoptic mange, but vets like to do a mange treatment first before trying to identify allergies. There’s a possibility your vet could be doing this, especially if there wasn’t a skin scraping that confirmed live mites. Mites are also hard to diagnose through the skin scrapings, so even a negative scraping doesn’t mean the dog doesn’t have the mites.

I haven’t personally used Revolution to treat mites, but I have read that it is an alternative to Ivermectin. We didn’t have any problems treating with Ivermectin, so we didn’t need to search for an alternative. According to this article Revolution is used to treat some breeds (like Collies) that have reactions to Ivermectin. There’s a good possibility your vet could be using this instead of taking the chance to find out if your dog is allergic to the Ivermectin or not.

Remember I’m not a vet or any kind of pet professional, so please take what I say as my own personal opinion and discuss it with your vet.

The smell of Promeris did make me sick to my stomach in the beginning, but after a few uses I guess I got used to it. If I were basing the product on smell alone I would have kicked it to the curb after one use, but the fact is it is the only flea treatment we’ve been able to use that not only did it’s job without irritating his skin even more but corrected what the mange treatments haven’t been able to do.
