What a Ball
Size: Medium, Style: Ultra Tug
Great toy for exercise for my fur baby and me! She never tires from this ball! German shepherd loves to play!! Perfect size for her. She likes to chew and it stands up! Throw it in to wash with her towels!

Best and most durable toy for our German shepherd
Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug
We have a German shepherd. This is our 2nd purchase. The first one was her first and favorite toy.
We still have the first one. But the strap broke (after a year) bc we didn't realize she hid it under blanket, and she chewed it in half. But after a year of hard play, the strap was worn out. She still plays with her ball, and often carries it with her on her walks.
It throws well and I love not having to pick up a slobbery ball. The ball is soft, durable, safe, and easy to play with.

Cord is not durable. Not for unsupervised play.
Size: Medium, Style: Ultra Duo Tug
My dog loves this toy and chewed through the tether in about 15 minutes, making it pretty useless as a tug toy. So the cord is not durable as stated. This is not for dogs who love to chew. Also, it is a bit smaller, much more squishy and chewable than a tennis ball, and I was worried she would chew it apart and that it might get stuck in her throat without the tether, so I took it away, much to her disappointment.

Color: Four colors, Size: 5cm (ball only)
Perfect size and strength for my small dog that is a heavy chewer! She hasn’t been able to destroy and chew up this one like she has with every other toy! Definitely chew resistant.
