Jolly PetsBounce-N Play Dog Toy, 20 cm, Orange 2073763

Q: Seller lists 8-inch ball & 8-inch diameter. What is the difference?

Hubby say's it is any way you measure it, is 8 inches... Mary

Q: Would this be a good toy for an over 100 pound GSD? he breaks everything.

Hey, just an addendum to the review I posted 5 years ago. The product has now changed, and is no longer the quality toy it was. I no longer recommend it. Even the private dog park where I first encountered it no longer uses these balls (note that all the good reviews are from about 5-8 years ago). It's really a shame, because it was a truly exceptional product, with durability that was nearly impossible to find. My GSD (now 7) still has his original ball and it's somewhat deflated but remarkably still in one piece and he absolutely loves it. I don't know why a company would change something working so well (another company took it over and decided to cut costs?) but it's really a damn shame. I can no longer recommend this product (which, in all fairness, is not even close to the product my German shepherd and I once fell in love with).

Q: is this the rubber plastic or hard plastic, like the egg?

Be sure you get the right ball. The Bounce-n-play is a thick-walled, semi-soft rubber or plastic that a dog can get their teeth into and can be used indoors (carefully), but is virtually indestructible for even the toughest dogs, like mine. The Push-n-play is hard plastic, for dogs that just like to push stuff around.

Q: Any difference in material/firmness between different color Bounce and Play Jolly balls?

There is no difference at all. You get a difference when you move between sizes. And of couse, the jolly without a handle goes a lot further. My boy prefers the one with the handle but will play with kinds.
