NOT for aggressive chewers

This toy is not for aggressive chewers. I wish I would have looked at the reviews first. Our GSP chewed the end of the toy off within 5 minutes.

Dog toy
Style: Bone
My dog loves this toy. As a matter of fact it is box favorite. I can't believe how long it has lasted him. He typically chews up and breaks his toys fast, not this one 😊

My puppy loves it but she is tearing apart
Style: Bone, Style: Bone
My dog loved the toy, she has fun with it, she is just 4 months old and she is teething. I just gave it to her for 10 minutes a day for the past 2 days (lost 2 baby tooth’s) but the toy started to break with her chewing it. Doesn’t squeak to much but I thought that it was going to be more resistant.

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!
