Dogs can do a lot of things. They can jump. They can grab rope. They can swing. Like here. This dog has some pretty good skills. Toward the end of the vid it becomes clear not all the dog's efforts were successfully realized (as in 'wipe out') -- he seemed OK, though, raring to go again, and from what we've been able to learn the dog wasn't injured or harmed in the process.*
* We did ask a couple dog "experts/friends" we know if this was bad news for the dog -- they said not necessarily...in fact (as it appeared) the dog seems to be enjoying it. On the other hand, they're not entirely sure (depends on the treatment and motivation of the dog). So...we're not endorsing this; and the falling part does make us cringe a little. At the same time, the dog has skills and perserverance...like a lot of awesome extreme sports athletes we know.
