This rugby ball looks very promising, so I bought it. Unfortunately, not so much with it my dog. Just chew it he finds boring after a short time. I must certify amazing durability this ball however. Normally my dog always gets everything up in record time. This thing still looks like on the first day.
For throwing and catching the ball is direct too heavy. Because I'm afraid that he deflects my dog a couple of teeth, when he meets him unfavorably. And to continue throwing and retrieving it is too heavy for me.
Conclusion: Not quite so bad, but also not really good. Best Regards.
