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!

Didn’t last 2 minutes
Not actually made of corded rope. Instead made with the most fragile materials this misleading, fraudulent company could find. Any potential buyers beware of this long string of tissue paper. I have been duped!!! Duped!!!
