My dog's pink skin is getting dark spots and red areas. Why?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | unneutered | 2 years and 4 months old | 65 lbs

His skin seems as if it is turning darker in some spots, where it usually is pink. I noticed the red spots, but he is on Trifexus (responds well) so no fleas and i give him coconut oil and fish oil for skin and allergies.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely a normal pigmentation change. If it is not associated with itchiness or discomfort, there is no need to be concerned about this. If you ever notice any discomfort or itchiness, have him evaluated by your veterinarian for further assessment and treatment. The red spots though do seem inflamed and inflamed and possibly represent an infection. You may use a medicated shampoo containing chlorhexidine to see if that helps as it may with very superficial infections. You may find that online or at your local pet store. Good luck and have a great day!
