Very durable and my Heeler's fave inside toy
Size: Large
My red Heeler loves these balls, second only to Tennis balls but she destroys those within minutes and they are outside only. This is her inside ball. She is hard on toys and has the strongest bite of any dog I've had (shepherds, collies, weimaraners, retrievers, Labs) yet these continue to last. She catches the ball, we play tug of war with it (she places it in hand hand and pulls only when I have a firm grip, she shakes it and flings it. The rubber outside even outlasts the water-bottle like plastic piece inside. Steps holds the ball with her foot and pulls on the rubber with her mouth, stretching it to sometimes twice its size. I pull while shes pulling. This thing gets abused daily and keeps on going. Its the most used toy and she brings it to me to play with every day. Each ball lasts about 6 months before the inside ball is toast and the outer rubber is finally starting to tear/break. which for me in an incredibly long time. If this ball is available to play, she wants it over all others. Shes NEVER gotten a piece off to actually swallow and that alone is worth the price.

Great ball but easily broken
Size: Large
I got this ball for my two dogs, one is a 90 pound yellow lab mix and the other 45 pound black lab mix. So far only my bigger dog has played with it and has also busted it. He was playing with it for probably half an hour just chomping down to make it crinkle and crunch. It's quite the loud ball!! I noticed the sound wasn't as loud so I took a peek and noticed my dog basically crushed the inner ball into a much smaller ball. He's still having a good time with it though. It's only a matter of time though that he's going to chew the outer shell because it doesn't make noise like it did.

Dogs go for this ball every time
Size: Large, Size: Large
My Boston's and Rotti love this ball. I had to get two more. It's great for the Boston's because they can grasp it with the way it's made with the softer rubber. They love the crackle sound. It's just the right size and weight for smaller like the Boston Terrier and Rotti. Easy cleaning, rinses right off.
