Excellent product, highly recommend
Flavor Name: Classic, Size: Large, Flavor Name: Classic, Size: Large
So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!

Dogs love them
Flavor Name: Beef, Size: Small
My two pups are power chewers. These bones are great! There’s no smell and pieces don’t come off like other bones. Although I am not a fan of the sound it makes when my dogs chew on them (nails on a chalkboard sound to me) they love them and it keeps them entertained. They are extremely hard so I limit their chew time (only because I can’t afford a trip to the vet if a tooth gets cracked) overall satisfied with my purchase, both myself and pups!

Durable Nylabone That My Dog Loves
Size: Large
This Nylabone chew toy is a winner! My dog absolutely loves it and has been chewing on it daily for months, and it’s still holding up great. The durability is impressive, especially compared to other toys that don’t last nearly as long. It’s become my dog’s favorite chew toy, and I love that it keeps him entertained without wearing out quickly. Highly recommend for any heavy chewers!

Worth the money
Size: Large
My dogs love these! I was buying them on Chewy, but there a little cheaper on Amazon. I guess they're flavored because both of my dogs love to chew on them. They hold up pretty well too.
