Why does my dog have red/black spots and mites after a wash?

Updated on September 23rd, 2025

Pet's info: Dog | Papillon | Male | neutered | 12 years and 3 months old | 12 lbs

I took my two papillions recently to a Pet Supply Plus store for a Pet Wash. I live in Indiana and felt the old weather would be be coming and so I let my guard down and order from 1-800 Pet Meds Advantage II. Now we are battling with numerous issues and festations that my little boys are traumatized about. I have found red mites, larva of red mites, black mites that are embedded in my white haired boy. Last night I had a magnifying glass that revealed some red mite attachment as well. HELP!!!

I would recommend that you have your dogs checked out by a vet. Dog mites (scabies and demodex) are not usually seen with the naked eye, they need to be visualized under a microscope. I think what you may be seeing is inflamed hair follicles and the brown stuff may be flea dirt (or the feces of fleas). If you are truly seeing crawling insects, then this may be a secondary infection, one that is not primarily found on dogs. A vet will be able to examine the skin and take a few samples for microscopic examination so a diagnosis can be made and proper treatment initiated.
