Hello, David and welcome!
My name is XXXXX XXXXX it will be my pleasure to assist you today.
I'm so sorry to hear that Maverick is experiencing this problem.
From your description, there's a possibility this could be ringworm, a fungal skin infection. Here is some additional information: Ringworm
It will need to be definitely diagnosed by the vet with a special light and in person exam, and if this is the diagnosis, Maverick will be treated with an appropriate anti-fungal medication.
Ringworm is contagious to humans, so be careful when you are in contact with him and wash your hands after touching this area (or better yet, don't touch it at all).
Other possibilities include an allergic reaction to something he was in contact with or a component in his food (sometimes, the manufacturer changes the formulation without your knowledge) and for this, the vet will prescribe an appropriate antihistamine or other topical treatment and suggest a diet change.
I hope all will be well with Maverick!
