Great toy:) but doesn't last long
Color: Green-M
This ball was actually really great!. I bought a few different toy balls for our puppy to play with and Aka (our puppy) found this one to be the best. Aka loves carrying things with his mouth. I also think he found it enjoyable, with all the pull tabs, to carry this ball around instead of trying to fit it in his mouth. I waited around 2 weeks to write this since that's how long it took Aka to destroy the ball:) At least it wasn't within the first day. We have a bigger dog an American Bulldog that's about 90lbs and he punctured this ball within the first day but it held up for a little. It's the same as a soccer ball really, not super tough and if you have dogs with big bite forces that are heavy chewers they'll destroy this so fast! But i like the design of this toy and I think it made a great toy while it lasted! It did deflate when it got punctured and held some air for about a week. With constant play it deflated completely after that. It was also the same size as a soccer ball.

Fun toy for dogs that like to fetch
Color: Green-M
The toy is great, good quality, and durable. My dog will only play with it if I am am playing with her, otherwise she loses interest and that is why I am giving it a 4 out of 5. She is a 60 lb. dog and the size. It is a good price for the product and when my dog does play with it the multiple tabs on it make it user friendly for chewing and tossing.

Surprisingly Durable Soccer Ball
Color: Green-M
Ethan is a a chewer par excellence. When his soccer ball arrived several months ago, I expected it to be a raggedy mess within days. I was wrong. The only chewed strap is the longer black one. All others are as good as new. The ball itself is a good size for him, a slightly larger Sheltie. It is one of his favorite toys for running and fetching play. As far as value for money, we’ve had several months to enjoy it without thinking of retiring it to the damaged toys bin. I would recommend it for durability and exercise play.

Total Glow in the dark entertainment
Color: Glow in the dark - L
This toy is my Aussie Shepherd’s favorite. It is durable. I love that in addition to playing fetch, the tabs make it possible for my dog to swing it from his own mouth and throw it in the air. The glow-in-the-dark feature is amazing! I throw the ball in the pitch black yard and watch it run back at me as my dog comes towards me. It's fun to watch!

Straps don’t last
Color: Glow in the dark - L, Color: Glow in the dark - L
My boyfriend’s dog chewed off all the straps in the first day. Decent ball, but why have straps that dogs can chew off so fast.
