Interesting topic! I guess I don't have anything too shocking. Willie used to sock me in the face with his paw sometimes when I knelt down to give him attention, trying to give me his paw with a bit too much exuberance. He gave me a black eye once and a few fat lips . Other than that, mostly bruises, scratches. Tasha chomped the nailbed of my thumb last year (accident of course, she was jumping to catch a stick that hadn't left my hand yet), and it was black and blue for over 6 months, hurt so bad when it happened it brought tears to my eyes.
