Dog Worker Puzzle by Nina Ottosson Liftable pegs, sliding pegs and a rotating center disc, this is the ultimate toy. Depending on how you set up the puzzle, it can be used as a level level 2 or level 3 game for your dog.
We had one of these (made for kids) when mine were small. They laughed so much and chased it around - I laughed too. This is the Crazy Pet Bumble Ball -Interactive Dog Toys--didn't know they made this for dogs!
