    For aggressive chewers
    Color: Blue
    My pup is an aggressive chewer and these keep him occupied. He keeps coming back for them. Go to replaced old chew toys. Only issue is he leaves his toys everywhere and if you step on them. They are quite sharp

    Not the best for REAL CHEWERS.
    Color: Blue
    My dogs love to chew and these didn’t last too long. It did keep them busy and I probably will buy these again but don’t expect much resistance of yours have big dogs that love to chew toys.

    Extremely hard and durable
    Color: Blue
    These are very hard , but my puppy lives them and my large dog can't tear them up, so that is a huge plus.

    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!
