Monday evening, I noticed Cadens ear was swelling like crazy. It ended up about 3 times the size of normal. He was bit by something, both on his ear and his eye. We took him in to urgent care and got a prescription for Benadryl. We think it was an allergic reaction to misquito bites. He's been so good about it. It doesn't seem to bother him much at all. He does occasionally pull on his ear, but no complaining. My little trooper.
