Play keep-away as you juggle, and your dog will likely go nuts for it! Also, you can juggle a couple of items (like toys), let them all fall, and watch your pup have a good time in racing around and trying to collect everything that’s rolling and bouncing. This may be better played outside.
Get inspiration from dogs that juggle (or help their owners juggles) on the worldwide web. Oh, they’re out there. And they’re amazing.
