This is a great toy that can stand the test of my chewing puppy. He has gone through tons of tennis balls, but this one doesn't even have a dent or scratch on it yet (he's been chewing on it for about three weeks now). While it is a great fetch toy, this is definitely an outdoor fetch toy. It is so solid that it could break something if thrown inside. Overall a great toy for the dog who likes to chew or fetch.
