WUNDERball Keychain

We have two dogs on the larger size and this does stop them from pulling. The only issue I have is if the rubber leash breaks from the buckel section of the leash. I can see me standing there with my dog happly running free and me looking like a dumb person without my dog at the end of a large rubber lead. Has that ever happened? Is there any reason or way to double attach the connection.

I purchased this toy for my Grandsons K-9 dog,, Kilo,, and he loves it out of all the toys we got him,, this is his favorite,, I was a little afraid of him swallowing it,, but he is having fun playing with it,,

It's a cute little addition to our house keys.
