This is probably caused by an allergic reaction. first of all make sure you de-flea Sadie regularly every month with a high quality spot on (ex. Bravecto) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or Cytopoint or Apoquel in order to stop the allergy.

I would suggest allergy testing so you can find out what the underlying cause is of her allergy. This should be done through a veterinary dermatologist or a vet that has a special interest in dermatology. Luckily it does not seem very severe at this stage but of course, you don't want it to progress further. It does not appear to be flea related in my opinion.

Mia is getting these rashes all over the same leg. I don’t know what to do anymore. We have been to the vet several times, they did a skin graft (later on I found more spots), she is an inside dog, I washed all fabrics and used knockout spray on top
She has a red area on the inside of her leg near her private area. It almost looks like dried blood but it won’t wipe off, maybe a rash?
