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!

Excellent for heavy chewers!
Flavor Name: Beef, Size: Mini
My dog is between 1-2 years old, and is a heavy chewer. So far the Better Bone is lasting very well! He still is chewing away at it! Excellent quality, and I appreciate that there’s no plastic that my dog is consuming.

By far ... the SAFEST and most DURABLE bone for dogs that are hardy chewers!
Flavor Name: Beef, Size: Large
After searching high and low for a NON-TOXIC, DURABLE and truly SAFE dog bone, I finally found the large, beef-flavored, HARD version of the BetterBone for my year-plus-old rescue (Carolina Dog).
1 - it's made of all NATURAL food-grade materials (cellulose from plant cell walls) ... which means no nylon, no GMOs, and no other artificials materials so it doesn't event stain your flooring. My girl loves the tasty beef flavor.
2 - the wishbone DESIGN is genius because it gives her 3 ends to choose from (nubs v raised edges v smooth) and ample ways to stabilize it on the floor with her paws.
3 - it is uber DURABLE in standing up to the hardiest of chewers (my girl gnaws on hers daily and sometimes even multiple 10-minute sessions per day). It works great to clean and reduce tartar on her teeth. The biggest surprise was that it took 6 months for her to gnaw it down to a size that was no longer safe for her (i.e. a potential choking hazard), so I donated it to a lady with tiny dogs at the dog park. At $20 per large bone, it's a good value.
4 - and most importantly, ... it is super SAFE. It degrades in tiny little pieces that could not possibly cause a choking hazard, and being all natural (i.e. no nylon - which most bones do have), there is no worry if she does ingest some of the particles. They vacuum up with ease.
The large bone weighs in at just over 12 ounces so it's kinda' heavy (9.25" long x 5" wide x 2" thick), but my 56 lb girl has no problem picking it up in her mouth before she hops up on the couch with me or into her bed.
Thank you BetterBone for making a superior product that is healthy, safe and fun for my pup!
