My dog is scratching, biting, and wincing. Is it more than fleas?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 3 years and 11 months old | 24.2 lbs

My dog has been scratching and biting at his skin. At first I thought it was fleas however I treated him a few days ago for it. Now when brushing him down he winces slightly when the brush (the soft side) touches underneath between his front left and back left legs. I can't see anything on his skin there although there is small black dots further over his body. I checked to see if these were fleas but can't see any movement.

You will need to take your dog to a veterinarian for a skin exam. Your dog could be suffering from an allergy, mites, fleas, a bacterial or fungal infection. each of these requires a different treatment, so it is important to find out what is causing the itch. Your vet will do a thorough exam and maybe a a skinscrape. He will then discuss the options with you and then prescribe medications, possibly give an injection to stop the itching.
