My wife just told me that Kira slipped on a wet floor, and did a "spread eagle". .She was wondering if she got hurt, but seemed ok.
Not knowing this, I took her for a good high speed workout. She was fetching at full speed, and showed no signs of slowing down.
It was after we got home, I first noticed a limp.
She's mushy, and resting, so I'll leave her alone.
