My 10 month male hedgehog has a red spot under his left front leg. If he had an armpit, it would be there. I was drying him off from a bath when the spot was first brought to my attention. I had tried to hold him on his back in my hand while holding his front leg out, but to my dismay he just bit my thumb. I didnt get a very good chance to look at it, but it doesnt look good. I give him flax seed oil every once in a whille with his food, and all other skin looks fine. Please help!
