Lots of fun for throwing, but not made for tug-of-war with a large dog
We got this ball a couple days ago and our dog loves it! The handle makes it great for throwing and he really enjoys swinging it around. However, I would not recommend using it to playing tug-of-war with a 35kg dog. Unfortunately, the handle came off as we were doing so... we're going to try fixing it (design is fairly straightforward) and in the meantime we're still enjoying playing fetch with the ball!
We got a few of these for our GSD who can destroy most toys quite quickly - these seem pretty tough and fly really well
Downside is they are pretty small (skinny rope and a smaller than tennis ball sized ball - and a choke hazard to our dog). Also the rope knot unraveled quickly, so we havent continued to use them. For a smaller dog (and with a drop of glue on the rope knot) these would be really good fun and great value
