Hi people! I noticed a couple of days ago that one of bubba's paws had a red sore on the side of one of his pads (fingers?). It looks red, irritated and it's a bald spot like he's been chewing at it. At first I thought that maybe he got a sticker bug (we're from texas so we call 'em stickers) in his paw and he was trying to chew it out which caused the redness. but it doesn't look much better even though I've been rubbing it with aloe. Should I worry? Could it be mange or something equally bad? I will upload pics when I can. Please help.
