First things first, ignore 90% of these reviews. The reviews saying these balls didn’t last very long clearly don’t know what they’re meant for. These are not “drop and play” kinds of toys. They’re meant to be used as reward toys. Meaning they get used during training sessions for a quick game of tug to reward the dog for good behavior. These are NOT meant for unsupervised play, and not meant for dogs who don’t have reliable recall or drop/Aus commands. That being said, my dog is 95 pounds and stands 29” at the shoulder. She’s a big girl who plays rough. Immediately after opening the package, we did a quick training session with these reward toys. They held up EXTREMELY well. They are made of rubber which means she doesn’t shred them in one short game of tug unlike some of the foam reward toys you will come across. I did have to tighten the knot below the ball before using them, but that’s to be expected with any rope style toy. If your dog does not have a reliable drop command and they are any larger than maybe 25lbs, I would not suggest using the smaller ball. If Nikita didn’t have a reliable drop command, it would be incredibly easy for her to wind up choking on the smaller ball. Even the large ball is pushing it on choking hazard size for a large dog, but again, reliable drop commands are important.

Good quality. 3 month review

My dog likes them more than the more expensive versions we have. Still in one piece and they get beat on, tugged with me and a dog or by 2 dogs both about 70lbs

Dog doesn’t like how it slams into his face from the weight

The balls were heavier than I expected and my dog does not like to engage with it even when I drag and throw them around to play with. To heavy duty for cattle dog

Great Training tool!

These things are great! I have a power chewing 8 month old Doberman who DESTROYS toys and he LOVES these balls. I use them on walks as a training reward and it has been a game changer. He loves these more than treats. Its not something I would leave for him to chew on his own in the house, but that's not what they're meant for. You use the rope to dangle and animate the ball so you become the most interesting thing on the walk. Then a clear drop command and you're back at whatever task you were working on. It's great to train recall, leave it, and reward for any good behavior. Highly recommend as a training tool, just remember to tighten the rope before you use it. Do not leave these things lying around your house and think you'll have a great result if you have a power chewer. Use as intended and you will be a happy camper!
