Unfortunately I ended up being very disappointed with this purchase, after about two weeks of use, it just stopped performing. Not sure what happened but it just stopped releasing the ball and I don't know why, it had no flexibility left to it. I'm not doing a very good job of trying to explain why it quit working but suffice it to say, it became useless after a couple of weeks. Broke my neighbors dog's heart, lol.

Perfect ball for dogs!

Size: Medium, Style: Medium (4 Pack), Size: Medium, Style: Medium (4 Pack)

Love these balls for my dog. They have a nice weight to them so you can throw them far. The material is very bouncy, so they do sometimes bounce over my fence, but they are very tough and not easily destroyed / very chew resistant. My dog is ~65lbs, it’s a perfect size for her, and she loves these and regular tennis balls the most. She is still able to squeeze it in her mouth, so it still has some softness / some give for her to enjoy.

Perfect toy for my corgis!

Size: Medium, Style: Medium (4 Pack)

Durable enough for my two corgis. Nonstop chewing cannot destroy these, highly recommend it!

Playing fetch for hours

Size: Medium, Style: Medium (4 Pack)

Tennis balls with the hairs pick up so much dirt and then that goes right into my dog's mouth. These are cleaner, my dog loves them, and they are easy to find when my pup decides he's done and drops it in the lawn or the snow. They hold up well after playing hours of fetch with my border collie.
