My dog loves it and it keeps her busy for a while. She actually pulls it out of her toy basket and brings it to me when she wants it filled. I break her treats into some pieces that are easy to get and some a little harder. This way she doesn’t get them too fast or loose interest if they’re harder to get. Also, she’s had it for 3 months and there’s barely a mark on it and she’s still a puppy that chews her toys to pieces.

Mostly happy

Color: Grape

Have a 1 1/2 yr old Belgian Malinois who needs things to do. I bought these and he loved it. Bad thing, it took him 1 day to chew the rope off both grape and pineapple. The stems on the cherry were also chewed off. The rest of the toy is intact and he still loves it.

Came apart.

Color: Cherries

We were playing with it and the green part pulled off of the red part. I'm pretty sure that is not supposed to happen. I took the green part away from the dog because that part is too small for my pup to play with. But we continue to play with the red part. My dog likes the texture and the bounciness.
