As of two weeks ago, Maverick has been scratching a ton. I checked his skin and didn't find any fleas, but I did find a couple sores. Rather than those being the cause, I'm pretty sure that he's just scratched himself so much the past couple days that he actually scratched himself raw in a couple areas.
I took him to the vet today, and they didn't find anything apparently wrong, so we assume it's some allergy from something. It sucks that we don't really know if it's allergies, or even what it's an allergy to, but he's on antihistamines for the weekend to see if that helps.
Best of luck, Mavdog.
