These aren't as durable as regular tennis balls for my dogs, but the softer pressure, slightly larger size, and biased colors make these a great win. I am making a huge assumption, but I suspect that the felt and squishiness of these is probably a little easier on their teeth, too. Plus, since they bounce less they're less likely to go over the fence. All in all, my favorite tennis balls for the yard and my pups prefer them.
