My puppy loves it. She figured out how to undo the knot, get the ball out, and tear apart the rope but she's still obsessed with it and keeps busy with all the dangling strands. She's teething so the ball is also a great chew option. It's a bit heavy to fetch with but we've got other options for that. I wish she didn't tear it apart so quickly but I think that's a her thing. It was still simulating and offered her something to solve/undo.
