my dog loves chasing this and he has not destroyed it yet

Pros: very bouncy, can't destroy

Cons: none

I LOVE THIS BALL! It is great for any powerful chewers. I know most of you probably laugh when you hear my reviews about how strong of a chewer my min. schnauzer is but it is the truth. I am going to take some pictures of the stuff he tears up next time and show them. This Ball is perfect! It is completely solid so it is very sturdy! It also doesn't have any dimples or nibs on it so there is nothing to chew off. It is about the size of a tennis ball and relatively heavy so it doesn't pose any choking hazard to my small boy. We play fetch in the house with it constantly! Sebastian can chew through the red original kong toy but he can't get through this because there is no place that is open for him to get a good ripping grip.

Pros: This toy has a completely smooth surface area so there is nothing to bite or chew off.

Cons: Can't think of ANY!

There is a kong ball down at our dog park, and it has survived many many dogs' mouths. Great ball.

Pros: Very tough

Cons: None known

These balls are great for shepherds since they can pretty much chew right threw any ball during the course of play. In fact these are the only balls I've seen that can withstand the shepherd jaw. However use caution when playing with these indoors because they are very heavy and can easily knock stuff over and cause damage to your home if thrown wrong. They also can bounce on hard surfaces so be careful of that. They're best played with outdoors if you have a big dog.

I didn't mean to give this a 1 out of 5 score. I'm new to this and I didn't see that part. I would rate this a 5 out of 5. Sorry about that.

Pros: Indestructible to chewing

Cons: Very heavy and can break stuff if thrown indoors

I take my dogs shopping 1 at a time so they can pick out their own presents to "exchange" with eachother Christmas morning. Graham picked this ball for Patch. Something excited him about it, maybe he just knows how Patch likes to catch! Hopefully this will last longer than the tennis balls he got last year!

Pros: durable, perfect weight/size,

Cons: none
