Great for power chewers

Nothing beats Nylabone!!! Our lab has destroyed everything else… even the extra durable black kongs. Finally a chew toy that is super durable and great size.

Large breed approved
Color: Blue
these incredible aggressive chew toys – they've seriously been a game-changer for my pups! I know it's a bit late, but better late than never, right?
I've got a couple of power chewers at home, a Rottweiler and a Labrador, and anyone with big dogs knows the struggle of finding toys that actually last. These bad boys have been in constant rotation for over a year now, and I'm genuinely impressed by their resilience. They're incredibly tough!
Funnily enough, we originally had three, but now we're down to just one. The others aren't broken, though – I'm pretty sure my dogs just loved them so much they've hidden them away in some secret stash, as they tend to do with their favorite treasures!
Beyond just being durable, these toys have been a massive help with their training. They’re fantastic for redirecting all that enthusiastic chewing away from my furniture and shoes, which, let's be honest, is a huge win for any pet parent!
Considering how long they've held up to some serious chomping, the price point is absolutely spot on. You definitely get great value for your money.watch your toe they are heavy.
If you've got a dog that's a champion chewer, you absolutely need to try these out. They're a lifesaver!

Durable chew toy.
Color: Blue
My dog loves these. She chews on them a lot. She seems to like the different shapes. She is part Pit and an aggressive chewer. These chew toys last a long time. And I love the three pack so if we lose one, we always have a spare.
