I don't do a lot of reviews because I realize many are objective opinions. However, in this case I felt it was necessary to warn others. Our dogs are aggressive chewers. Their last rubber bones (not these) which we've purchased before, and recently purchased again, were destroyed quickly. Chunks of rubber came off the ends. Since those didn't hold up like they used to, I found these harder bones hoping they would last longer. They were able to gnaw into the hard plastic within a few minutes. This created sharp edges that cut their mouths. When I saw a bit of blood on the bones, I took them away from the dogs and threw them away. I wondered why they quit chewing on them after being so excited at first. Also, these are hard enough to damage a tooth.

Pups have shown zero interest in these toys….

Color: Purple & Blue

I would agree that these are indestructible being neither of my dogs have shown any interest in these at all. At this rate they should last forever…

Durable but losses interest

Color: Purple & Blue

My dog is an aggressive chewer. She was interested in this toy while it was new, but soon after lost interest. Good news is although it took a beating it did not break or splinter. If soppy toys are disposable in your house, give it a try.

Still squeaking after all these days!

Size: Jumbo, Style: Beef

My power chewer GSPs usually wreck all "tough" toys in less than an hour, especially if they squeak. These seem pricey but I can say it's held up really well. After about three weeks, it's still hanging in there! The stripes are worn off but the squeaker still squeaks and that's what it's all about.

Long lasting scent and has not been destroyed by my heavy chewer.

Size: Jumbo, Style: Bacon

My medium puppy loves this ball. She already has the smaller size but appears to enjoy the challenge of catching the large one. An added benefit is it's easier for me to win it back when we fight (play fighting) for it. The scent really lasts. I've had the smaller version for a few months and the scent is still there. Does it really smell like bacon? Not to my nose but the puppy thinks it's awesome. The ball itself is really tough. The pup can destroy a tennis ball in a day. Except for a few teeth marks these balls are holding together great.
