We had the smaller size for 3 weeks now and the XL for 2. Our Mr. Knightley, a heavy duty chewing 75 lb Pitbull has destroyed the competition Black rubber Heavy chewing products in less than a week. These balls have lasted this time with just little indentations and chew bite marks but the integrity remains. He has not been able to "scissor" bite through them nor "Corn Cob nibble" the rubber off!
We are very impressed and will be Monster K9 customers for ever!

My wife bought these thinking that they would last longer than most of the toys that we buy for our German Shepherd. To our surprise the frisky and tug stick are just as tough as they are described. Thank you so much.

He is the type of dog that tries to destroy every toy I buy. The ball and the ring that I purchased from MonsterK9 has got him stumped. He has had these toys the longest out of every other ball I have purchased and they both are still intact without any missing pieces. Well worth the cost. I would recommend along with purchase again.

Anything I bought Overseas, Max ate it or Destroyed it immediately!

I can finally feel Safe leaving a Chew Toy with my Malinois.
I didn't know what Max was Going to Do with Monster K9s Frisbee?
It's become his Favorite Toy!
He Loves to Fold It in His Mouth like a Big Taco and Go to Town on it!
Any Monster K9 Chew Toy, One is not enough!

We have a Dutch Shepherd that is a power chewer and destroys toys designed for a heavy chewers. This toy has held up great. We will be back for other styles.
