My dog has a warm, rough, hairless pink/black skin patch. What is it?

Poor Star! I can see that she has a large amount of redness and hair loss on her shoulder and thigh in the photo. Yeast infections, bacterial infections, mange, skin allergies, and even certain hormonal imbalances can cause these signs. Because of how severely affected the area seems to be, I definitely recommend having Star seen by a vet, as she likely requires prescription medications. I hope all is well!

Poor girl. I would highly recommend having her tested for demodexx mites, hypothyroidism, and a fungal infection. Either of these can cause these symptoms, but they can also all be treated with relatively good success. Best of luck to you at the vet. Best wishes and take care.

I would recommend that you have Scout examined by a vet. It could be a bacterial infection, ringworm, demodectic mange, or something else. The vet will probably do a skin scrape to see what organism is causing the hair loss so that she can get appropriate treatment.

It could be caused by a bacterial skin infection, ringworm, mites/parasites, or allergies. Have your vet take a look at her to determine the cause. Your vet can do a skin scrape and /or culture to help diagnose and treat. You could try to bathe her with a medicated dog shampoo and see if that helps.

From the photos here it looks like these are patches of hair loss. We can have hair loss at points of pressure if a dog likes to lay on hard surfaces, but we also worry about things like ringworm (a fungal infection), skin mites, and bacterial infection causing patches of hair loss. I would recommend bringing your dog in to the vet to examine the area. They may recommend a fungal culture if ringworm is suspected or a cytology of the skin to check for bacteria or a skin scrape to check for mites.

It looks like she could have a mild skin infection. You could bathe her with a medicated shampoo, like Epi-soothe and see if that helps. If not, have your vet take a look at her to determine the cause and treat. Your vet can do a skin scrape, cytology, and/or culture to help diagnose and then prescribe medications to treat. She may need an antibiotic, anti-histamine, corticosteroid, and/or other medications depending on the cause.

I would have April examined by a vet. It is not easy to see what is going on from just a picture. It could be a foreign body under the skin, an infected puncture or other wound, a mass, or the start of some other skin disease. The vet will do an examination, and may take a slide impression or needle sample for examination under a microscope. Once they have a better idea as to the cause, they can decide on the best treatment.
