Chuck it further than your skinny little arms can chuck it. Doggo loved this, I loved this and when we were done Doggo promptly hid it under the porch so I couldn’t take it from him. It’s not a squeaky toy, it’s for fetch. You wing it out toward the yard and it flies, bounces if it’s lucky then is attacked in an adoring manner. We like it!!

Great to exercise the dogs!

Style: Sport, Size: Large

Great to throw 3” KONG Ball (RED) with hole thru it! The thrower is the best to exercise dogs with retrieving balls!

My GSD's Emotional Support Balls

My GSD has three of these and they are undoubtedly his emotional support balls. I bought these so that the medium ones wouldn't get stuck under our couch and make him spiral. He takes one everywhere, it keeps him company in his bowl when he's eating, it gets dropped in my shower, it goes potty with him, on walks, it falls out of his mouth when he falls asleep. These are the equivalent of a GSD pacifier. Best Purchase I've made hands down. Plus they don't get stinky after being constantly covered in dog drool and if they get dirty/ muddy/ hairy a decent rinse will do the trick . They last a LONG time with my super chewer, they are firm enough so that when he gets a good chew on it it doesn't fall apart. He has endless hours of obsession logged into these balls.

Great Durability

Even my heavy chewer GSDs haven’t destroyed them…yet. Easier on your shoulder if you buy the ball thrower.

Dog loves this ball.

Great ball. The dog loves chasing it and it bounces in different directions so she can’t anticipate where it goes. So far she hasn’t been able to chew through the ball. She Is a medium sized dog.
