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.

Need suggestions

This was a great toy but my 9 month old puppy (65 lbs ). Chewed it up within 3 hours. Any suggestions? I am really trying to find a tugging toy that can with stand him. He is a significant chewer.

Super fun concept, but material needs improving.

Size: Small, Style: Ultra Tug

The concept - amazing. The materials used? - not so much. Our senior Chorgi is not even a super chewer,yet he managed to get a tiny piece chewed off of the ball in under 10 minutes. Also, the handle is not flexible enough. It's like a hard, tough, sharp and thick nylon material. You can see how they were trying to make it more durable,but there jas got to be an alternative material. This nylon is sharp on their gums and roof if mouth. For now I am watching our dog carefully with it, because he loves how it bounces funny so its more fun to chase. Fur babies are pur children. You would not leave a 2 ur old alone to play with a toy, would you? I'm just not sure i'd buy another. I bought 3 at once. Returning 2 .

Great toy!

Size: Medium, Style: Ultra Tug

We have a 1 yr old rescue (German shepherd mix) and she didnt really know how to play with humans, she was scared of everything. We got this toy to help us teach her how to play fetch and tug of war and it really helped her come out of her shell. She loves this toy! It is very durable and fun to throw. Just enough rope to tug with her and doesn't come apart like other rope material. We got medium size and prob buy another one.

Durable and fun

Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug

This is a cool toy. My dog took to it right away. It tosses great. I like that you can play a little tugging along with fetch. We mainly use it outdoors. It feels very strong and durable. For size reference my dog is a mini golden doodle and weighs about 30lbs.
