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.

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.

Bulky

I was a little disappointed in how bulky these were and seemed hard to get on. If you can get past this they do seem to work good. Hands do seem softer and a bit healthier.
