The Boxer, Che Guevara, takes on a Hexbot Nano!
These things are fun, and cost about $10 each. There are bigger ones that respond to light and sound, and smaller ones that are dumb and just skitter around.
It probably isn’t a good idea to put small and interesting mechanical objects within paws reach of a dog, so be sure to keep a close eye if you do something like this. Eventually, the dog will grow some balls and attempt to eat the thing.
By the time I filmed this, Che had already gotten enough confidence to keep it in his mouth for a few seconds. He probably won’t be allowed to play with it much longer.
