My dog has hair loss, red eyes, and dark, dry, itchy skin. Why?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 2 years and 11 months old | 92 lbs

My dog has been experiencing hair loss, his eyes are red and the places where he is losing hair are his back and tail and they’re starting to turn sort of black or grey it’s starting to look like dry skin. He constantly licks back there and scratches himself a lot.

The most common reason for change of skin color and itchy skin is fleas. I would recommend keeping up with a monthly flea prevention. Even if you are not seeing fleas on Rockey he could be bitten by fleas causing sensitivity of the skin. IF you are using flea prevention monthly than it is possible Rockey is having environmental allergies that need medication from a vet to resolve. I would recommend taking Rockey to a vet to make sure the skin is not infected and stronger medications are needed. hope that helps
