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.

Fun, Durable Balls for smaller heavy chewers

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.

Great quality

Color: Four colors, Size: 5cm (ball only)

I was very surprised that these are as good as the chuck it balls. I have a super chewer and he’s tears balls up except for chuck its and he can’t tear these up.
