No, I don't think anything with a hoof could float on it, hope not! We get quite a wind, the drifts can get so bad even 6-foot fences can be useless. 4 of my chis are reliable racers, but sometimes all 7 go around it together at top speed. The old grandma dog likes to cheat and will turn around half-way, come back the way she came and look up at me like she's the coolest kid ever... which she is, of course... Sometimes I put out agility equipment along the path, but that's pretty limited right now as parts of the path are getting too icy for speed.
