Best dog toy for extremely aggressive chewers!!!
Size: Large
Absolutely a great dog toy for extremely aggressive chewers! I have a pig pitbull that loves to chew! He has chewed through every toy I have ever bought pretty much right after I give it to him. This thing is durable he hasn’t made a hole or a tear in it yet and he hasn’t made went to town on it when I first gave it to him! I’m impressed!

Kong Works Well...
Size: Medium
Our German shepherd chews every ball we've ever purchased. The other balls are easier to throw for this 75yr old lady. But this Kong ball will out live any other ball I've ever gotten him. A tennis ball doesn't last an hour. Some other name brands takes him a full day to chew up. So far he's tried but gets nowhere with his new Kong. I seriously believe he just might not be able to chew this one up. Thanks Kong. I got the medium and it's a large ball.

Good For Heavy Chewers So Far
Color: Onyx Black - Most Durable
Solid quality. My Doberman is a power chewer and I am looking for a toy that he can't destroy in 2 seconds. If a ball lasts more than an hour it is a miracle. It has a sturdy design and is more heavy weight than the other "non-destructible" balls he has. He has only had his ball for one day so we will see how long this ball lasts him. It is the size of a tennis ball, firm, little to no bounce, and seems built for heavy chewing.

Great Product, 2 years and running!
Color: Onyx Black - Most Durable
It’s been almost 2 years and my dogs haven’t destroyed them yet. I have a Pitbull and a Pit/Cosro mix. They destroy every toy we’ve given them, except these toys. Great product 100% worth the money
