Short final at Cottonwood, Az, a large dog appeared through a gap in the fence bordering a housing subdivision alongside the runway and ran right across in front of me. "Oh well", I thought, "He's gone now" and continued the approach.
What I hadn't reckoned on were the kids who were chasing the dog! They burst through the fence and ran right across in front of me as I was about to flare. I pulled up, zoomed over them, and touched down beyond, needing all of the runway remaining to stop.
I should have gone around (or somewhere else) at the first sight of the dog of course. As they say, "I learned about flying from that".
