So it’s great toy and had our dog entertained immediately. However probably won’t last very long with medium to large dogs that gets obsessed with killing every toy you give them. Our Pitt mix loved this until she ended it by chewing through the heavy plastic ring that keeps the ropes connected. Without the noted ropes attached, the toy cannot move around. Basically ending the fun. Would be great to start a puppy or smaller dog on. It has multiple modes and is noise and proximity activated. Our dog was obsessed but sadly it was no match for her. 3 stars only because it didn’t last more than two days with our dog.

Obsessed, crappy rope

My pitbull mix is obsessed! I was worried he might break it, but he has used it everyday for the past week and we've had no issues. The reason I docked a star is because the rope it comes with lasts minutes. I'm still trying to figure out a good solution of what to tie onto the top. Regardless, he loves it without anything on it, but he chews on the connector piece so I'm worried he will break it if I let him go.
