He could have some kind of skin infection.  But I should tell you that’s a really general diagnosis and I don’t know for sure what’s causing it.  Do you have any other information?  Do you have a picture of his scabs that I can look at?

I don't have any pictures. What typically causes skin infections in dogs?
user
Well, the bacteria or virus that cause the skin infection will dictate the symptoms that they cause, and the treatment that you should give. I know that dog skin infections can be caused by a yeast, such as Malassezia pachydermatis.  These yeasts might show up in a ring around the skin.  They can also cause hair loss, but that doesn’t seem to be the case here.

I see. Are there any products I can buy to treat him myself, or do I need to go to a vet?
