My dog's skin is dark and itchy. Is it mites, bacteria, or infection?

Updated on September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | unneutered | 6 years and 4 months old | 70 lbs

My dog’s skin is turning a darker color around his legs and arms. Also he is bitting on those same areas profusely. I’m afraid he has mites or some type of bacteria but I am not sure.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Titian!

The dark thickening of the skin indicates chronic skin disease. It can be from a bacterial or yeast skin infection, demodex (non-contagious skin mite), scabies (infectious skin mite) or even ring worm. I would highly recommend having Titan seen by your Vet next week for an exam. They can do a quick cytology of the surface of the skin to check for bacteria and or yeast and also do a skin scraping to look for mites. Regardless of the cause Titan is obviously uncomfortable.

I wish Titan the best!
