      Tough
      Color: Medium size (5.9")
      So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.

      INDESTRUCTIBLE!
      Our lab chews through every “indestructible” toy within a few hours. This ball is amazing! He has not been able to destroy this toy! Highly recommend for your most aggressive chewer!

      Our dog is very happy with this ball!
      Our lab is an aggressive chewer and LOVES his toys. I was looking for a chew toy that had a different shape than a regular ball or Kong and saw this. Our dog LOVES this toy because he can chew it when he wants to be alone and it keeps him entertained (especially when stuffed with food). He also plays "catch" with us by rolling the ball toward us with his nose. So far there is no indication that he is damaging it so I'm very pleased with the durability.

      Bouncy and firm
      Lasted a day so far! I'm hopeful it'll last at least a week. Light enough to bounce compared to her Kong ball.

      Thus is Great
      They so far are indestructible in the jaws of my two large German Shepards. To be fair, this is NOT a ball to toss because it seems to be more in the cannonball family than in the soft dog toy world. Each of my pups love their Monster K9 balls but when they drop it on our hardwood floors, the whole household knows where they are.
