Our neighbor has a lab that's trained exclusively as a duck dog. My wife and I play with her on a daily basis and these Chuck It balls and her favorite retrieval toy and hold up well to some of the most aggressive chewing I've every seen - she non-stop chews on the ball during 45 minute play times. As a duck dog she's trained to retrieve in water and these balls float very well and she's never been able to puncture a ball despite her chewing. A great value that lasts.

great sturdy ball for aggressive chewers!

This is my 100-pound doodle's very favorite ball - he is obsessed with it. I keep at least two in storage at all times just in case his goes missing. He is a strong chewer and these are VERY difficult to destroy - not completely impossible (he put a gash in one), but pretty close!

Better than tennis balls for dogs

Color: Orange, Size: Large

My trainer said better for my German Shepherds than tennis balls. They seem to like them, and they last a lot longer than regular tennis balls. We started using regular tennis balls as the dog ones broke first time out. They still managed to break the regular tennis balls also, just not a quickly. Once I found out tennis balls were not good on their teeth I bought these. The rubber ones are great.
