My German Shepherd LOVES LOVES LOVES this thing. I’ve purchased about 5 of them, not because they don’t last (they do), but so we can have them everywhere (one in each car, the backyard, the front yard, the house…). The string makes them so easy to throw far and you don’t have to handle a sloppy foamy tennis ball. And it’s great for playing a little tug. All in all, a winner of a product!

Strong ball for Strong chewer!

Perfect Size. This foster pitbull likes to tear stuff up, this ball has not ended up in the garbage like so many others have.

Good Toy Reward for Training

Size: Medium, Size: Medium

A great non-food reward for dog training and play! It’s the perfect size for my German Shepherd and the tie makes it easy to carry and play tug. It’s also been very durable for her sharp teeth!

Didn’t last long

Size: Medium, Size: Medium

One of my puppies chewed the rope apart within an hour. They still have one of the balls and play with it often.

Good for playing tug of war, but better with a knotted handle

Size: Medium, Size: Medium

Strong and durable rope ball. I use it to play tug with my Doberman Pinscher -- at least until she decides that she's taking it, then she does!! The size is good, list of price is a good value for two, and my dog has a lot of fun with it. As you can see in the picture, there was not a knotted handle at the end. I was never a boy scout and don't know my knots and so anything I try to tie comes apart when we start playing. It would be nice if it came as it looked in the listing: with a knotted loop at the end.
