Dog losing hair, bald spots, and white skin patches. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Staffordshire Bull Terrier | Male | neutered | 10 years and 8 months old | 44 lbs

My dog has a unidentifiable skin condition. So far he has been prescribed antibiotics and cortisone neither which have helped. He was getting red sores but they now have turned into bald patches starting on his face and now down his back and tail. He also has white spots appearing on his stomach. It doesn’t seem to bother him and he is not itchy but he’s hair is dry and falling out constantly. Our vet suggested a skin biopsy but that’s a lot of money has anyone seen this before?

I'm sorry to hear that Barney is having so many skin problems. Skin disease is frustrating for owners and veterinarians alike. A lot of conditions can look similar, but have very different causes. I would recommend he is checked for ringworm with a fungal culture and that mites are ruled out with deep and superficial skin scrapes. I usually place the patient on flea and tick prevetion to ensure the skin disease isn't secondary to these parasites. It is less likely that he has allergies if he isn't responding to the cortisone. Occasionally skin disease is secondary to an underlying hormonal disease so bloodwork maybe warranted. If none of this helps, then I agree that he will need a skin biopsy. I hope this information helps. Good luck!
