Just today at flyball practice Halo slammed into my thigh, head first, HARD. It's not looking bruised yet, but I expect that it will be by tomorrow. It hurt bad. She also bent back my fingernail going for her tug, and separated part of the nail from the nailbed. That smarts too! A few months ago at a flyball tournament she outed her tug, but then leaped at it again as I was putting it around my neck - she missed and got my breast instead. That was a VERY nasty purple and yellow bruise for over a month.
One time when she was younger she was so excited when I got home that when I let the dogs out of the garage pen (they have to sit and watch before I open the door), she leaped up and muzzle punched me in the face in her enthusiasm. I was pretty sure she'd broken my nose at the time, but fortunately it was just painful, not broken.
Another time I was training her at a strip mall, and again she got excited and jumped up at my face and managed to get me right in the eye. I don't know if she jammed my own eyelashes into my eye or it was her whiskers, but OMG, that hurt. I couldn't see, my eye burned and started watering, and I had to take her immediately to the car and drive home. It was hours before it started feeling better.
But what's even worse is the time that I was still in bed one morning and Tom let the dogs out of their crates, and they both ran outside to do their business and then came back in. Keefer jumped up at me on the bed (which he NEVER does), and his toenails scratched my eyeball. Let me tell you, a corneal abrasion is extremely painful! That time I had to go to the doctor, and I couldn't see right or get my eye to stop watering for several days.
At agility class with Dena, years ago I tripped over the metal support for the tunnel because I was watching HER and not paying attention to where I was going. I landed with my right arm extended above my head, and I broke my shoulder - a humeral head fracture. I didn't know it was broken at the time, and it was exactly halfway through the class, so I continued, working with her on my left side only because I couldn't lift my right arm more than a few inches from my side without intense pain. That was week 5 of a 6 week class. I showed up the next week with my arm in a sling and finished the class.
I've had numerous bumps and bruises and nips, too many to mention.
