Proof that ninjas come in all shapes and sizes, this is a video of Monkey the dog making a ninja warrior style obstacle course look like a cakewalk. I thought the bare rope bridges and the front paws on balance beam/back paws on wall crossing (above) were particularly impressive. My dogs? My dogs could never do this. My dogs won’t even do things for treats. I mean they’ll eat them if you throw them close enough to where they’re lying, but they won’t do anything for them.
