You appear to be describing a superifical spreading pyoderma - a Staph infection of the skin, usually. The brown splotches are epidermal collarettes - roughly circular skin lesions that begin as pustules and then spread out. The center of the collarettes quiets down and often hyperpigments as you've seen while the rim of the collarette can remain actively infected and inflamed. These pyodermas are usually addressed with an antibiotic in the cephalosporin class such as cephalexin as well as an antimicrobial shampoo containing chlorhexidine. The antibiotic is by prescription only through an attending vet. The shampoos can be found over the counter. Malaseb (https://www.amazon.com/Malaseb-Shampoo-Bayer-Healthcare-473/dp/B00061MP5G) is a good choice when used twice weekly as it can hasten resolution of the infection.

Please respond with further questions or concerns if you wish.
