I can't tell you the number of times Star's cracked my skull! We'll be playing on the floor and she'll whip her head back and BoINk! A few times she got me in the nose and I was sure she'd broken it! When we're playing outside, sometimes she'll come running at me full speed and plow into the back of my knees (sandbagged!) or side of my leg and down I go! lol! She's a tough little bugger! 60 lbs of fur power! Oh, they BOTH love to step on bare feet! Sounds minor, but they're heavy! And Cody's a "toe picker!" When she wants my attention, she'll come over and paw at my leg!!! With shorts on, if her nails need clipping, that can leave a nice scrrrrrrrratch!
