The ball is excellent for larger dogs with strong teeth. It will take a long time for a dog to destroy if yours is the type, like mine, that shreds balls in minutes. This ball is still intact, minus a good few teeth marks, after a few weeks of playing daily in the park and garden. I don't expect it to last forever but it is doing a good impression so far.
These are great products, tennis balls don't last 5minutes with my dog. So called other durable rubber balls are just as bad. At last I have something that will last a long time before it shows any sign of wear. Good solid rubber, good price, great size too. Top marks.
