Rope comes out at the slightest force. Pointless tug toy!
Color: Four colors, Size: 6cm (with rope)
If your dog pulls on these (and why wouldn’t he?), the rope immediately comes out. Turns out they just fuse the ends of the nylon rope together, which is no match for a dog playing tug. Any dog, any level of pulling will dismantle these.
We’ve managed to reinsert the rope to a couple of these and KNOT it, which gives you a shorter rope but a toy that can withstand some play. But if I had wanted a DIY toy, I’d have used the balls and rope I already own.

Not for super chewers!
Color: Four colors, Size: 5cm (with rope), Color: Four colors, Size: 5cm (with rope)
These rope ball toys arrived today. My poodle puppy loves rope ball toys and playing tug of war. These didn’t last 10 minutes. For context, she is 1 y.o., 30 lbs., is not teething & has her adult teeth. She did this on her own- we were not playing tug of war at the time the toy fell apart. At least there are 3 more in the package & when the rope is done, we’ll still have the balls to play with.

What I've been looking for
Size: Large (Pack of 1)
Just got my Nero Ball. Only used it once, but really like it. I've tried other "ball on a string" type toys, with unsatisfactory results. I'll be using it as a training reward, and my boy, who is a pretty ferocious tugger, is going to learn 2 new things with this ball. 1st, to target the ball instead of the rope, and 2nd, that it's for a little gentle tugging instead of the full throttle stuff he does otherwise. After our 1st session with the Nero Ball, he's picking up on the new rules quickly. We'll see how it does long term, but I think this is one I'll stay with.
*UPDATE* Been using my Nero Ball for a month now. I'm tempted to call it the 'Hero Ball' because it's just that terrific!! For me, the key has been putting in the time to allow both myself & my dog to develop the skill to use this tool smoothly. May sound strange, but using a toy as a training reward requires practice, and each different toy configuration requires different handling. It's time well spent - we're both having a lot of fun!
Kudos to the designer of this ball. Every detail has been carefully considered, from the length & material of the rope (just the right length that the dog won't step on it; material is easy on the hand while still being tough enough to withstand a few toothy grabs; the loop is the perfect size to grab for a little tug or to pass the ball through to slip-knot it onto a belt loop). The ball is also just right. The knobs make it non-slip, the rubber eliminates tennis ball fuzz concerns, and being semi-hard and hollow makes it slightly compress-able, which makes it a higher value reward than a solid ball that can't be compressed.
While this ball will not work for every application or for every dog, if you carefully read & understand the information provided and don't expect it to work outside those parameters, you will be pleasantly surprised by a very well designed, well constructed tool that you can use to enhance your training or play sessions with your dog.
