Does your buddy have a name?
Is there obvious signs of infection? If so, is there improvement since you started him on the Baytril?
It is hard for me to tell from the photo, but from what I can see (fur loss as well as more of a pink/grey color as opposed to red), is this perhaps an injury that is already healing?
Note: This is a question not an opinion, and again, hard to tell from photo.
Any chance of a more recent and more closeup photo?
I had a wild named Mama Squirrel who came by with a terrible looking injury to her front paw back in 2020. While she lost a finger, she healed up just fine with clavamox, and was around for another four years after recovery.
