Why is my dog losing hair with a raw, crusty spot on his neck?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 4 years and 1 month old | 80 lbs

I gave my dog a bath one day and later that night I noticed a patch of hair missing from the back of his neck it has now been there for about 2 weeks and has gotten bigger. When I first happened it looked like raw skin and then had a puss like crust to it and now it looks like it is back to the raw skin but more hair around it is gone. He did have fleas and that's why we gave him a bath. It also seems like I hurts and when it had the crust it itched. Please let me know what I can do?

This sounds like it could be a hot spot or superficial bacterial skin infection. Most of the time hot spots are treated with antibiotics and sometimes some prescription topical medications. I'd recommend making an appointment with your veterinarian.
