Not as tough as they make it seem
Color: Buck Wild, Color: Buck Wild
My dog chewed it up and destroyed it in less than 4 hours. I have a GSP 8 month old. She’s definitely a super chewer but this didn’t last at all. The tail crumbled apart and she ate some of it.

This is a HEAVY Toy
Color: Buck Wild
This toy is HEAVY. Really good quality, but my dog hasn’t shown much interest. If you can find a way to get your dog to play with it, I’m sure it would last for awhile.

Barkbox Betty
Color: Betty Bigfoot
A lot smaller than pictured. Still like it. Durable. Dog likes to carry toy around. Dog is 70 lbs and a heavy chewer and toy has lasted.

Fave dog toy!
Color: Betty Bigfoot
Great toy! My dog prefers the ball inside which is great for chewing on, bouncing, and playing fetch. Very thick rubber, lasts a good while. The outside cover is pretty tough, but for those who like a challenge it should last a little while. It really depends on how determined and fierce the dog is about chewing! We’ve had 3 of them. We always keep a back up for when one expires!!

Perfect for Heavy Chewers—Huge Hit in Our House!
Color: Aurora Beast
This toy is an absolute favorite in my house! My dogs are usually pretty picky and can destroy most toys within minutes, but this one has seriously impressed me. It’s super durable while still being soft enough for them to carry around and cuddle with.
They’re completely obsessed—whether they’re chewing on it, tossing it around, or just walking around proudly with it in their mouths. It keeps them entertained for a long time, which is a huge win.
Definitely worth it if you have strong chewers and want something that actually lasts. I’ll be buying more from this line for sure!
