Hi all!!
My little guy Squeegee has what looks like an inflamed or infected knuckle on his back right pinky (see photos below)!

He is still very active and running around and this is the first day Iíve seen it. I tend to be pretty aware of any physical issues with him so hopefully Iím catching it before it spirals. What should I do? I know different antibiotics are recommended for different ailments (plus dosage differs of course). I also may need some advice on how to acquire antibiotics (Iím in Southeast Michigan). Thank you so much for any help!!!
