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.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.
