Just received the large ball. Construction appears to be excellent and time will tell with my aggressive chewer. That being said I ordered the large because our Mini Goldendoodle loves playing with our daughter’s dog large ball. I may not have read description close enough but ball is solid and weighs a considerable amount. Our dog soon learned to pick it up but I’m just disappointed that it isn’t hollow like ones our daughter has.

Love this

Size: Medium

My dog is a beast and loves to shred through any toys we get him but with this it’s keeps his teeth busy and off the furniture and there is no signs of any damage. Super high quality and perfect for any fur baby that’s loves to chew

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.
