Anyhow, we took Carson to the vet and it was found he had a slight infection but was otherwise okay. Part of his treatment plan, though, besides light antibiotics, was to wear a tshirt to protect his chest a bit from his dirty paws scratching at his itchy skin. He seems to really not notice it at all.
I think it's possibly the cutest prescription ever asked to be filled.
He's doing much better and is backed to being coddled by me and mom with daily belly rubs and a few trips to the treat can to make up for our absence. :)
