Durable & great deal
Color: Orange and Yellow
My foster German Shepherd has a jaw that's locked and loaded but love these cause I can play tug of war or fling it way across the yard. He's chewed or busted every ball he's received except these. I'm loving them. Very durable, bounces too really well and I can find it easily with the colors.

Small balls and came apart
Color: Orange and Yellow
My dog loves them; these are my first set of this type of toy. Good quality materials, but the knot in the rope came undone and the ball came off in 3days. I had someone fix and re-tie and it has held up so far. The next set I’ll get in a larger size, they’re a tad small for my dog’s mouth.

The Chuck Norris of Dog Toys
Color: Orange
If dog toys were superheroes, the Nevperish K9 Training Ball would be Batman—indestructible, effective, and always ready to save the day. This thing flies. I’m not saying I could take out a rogue squirrel in a single throw, but… let’s just say those little guys know to keep their distance now.
My 100lb German Shepherd, who we affectionately call "The Toy Terminator," has destroyed every squeaky, chewy, or bouncy thing in her path. But this? This glorious, rope-swinging masterpiece? She’s met her match. It’s like her teeth have signed a peace treaty with this toy.
Speaking of flying, if you have neighbors with a backyard that’s less than a football field away, be prepared for some fence-hopping cardio. I’ve had more awkward encounters with my neighbors than I care to admit. Thankfully, my shepherd has learned the art of the double hop—over their fence and back—like some four-legged ninja gymnast. Bonus: great entertainment for the neighbors.
This toy isn’t just a ball on a rope; it’s a lifestyle. Open fields? Perfect. Tug-of-war? Immaculate. Backyard fetch? A cinematic masterpiece. It’s basically the Swiss Army knife of dog toys, minus the danger of accidental stabbing.
Pro tip: Don’t underestimate how far this thing can go. My first throw ended with the ball in orbit—or maybe it just bounced off a satellite. Either way, my dog was thrilled, and now I need an arm warm-up routine before playtime.
So, if you want a toy that’ll outlast your dog’s dental fury and make fetch sessions the stuff of legend, this is it. 10/10, would absolutely get weird looks from neighbors again.
