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!

Best chew toy we have ever purchased.
Flavor Name: Classic, Size: Large
My moderately active 80lb Lab - Pit mix has been steadily working on this bone for over a year. He doesnt chew it every day but he does regularly chew it for 30 or more minutes at a time. He has only been chewing on the smooth end, and the only wear it shows is a slight thinning and some grooved tooth marks. It has not had any chunks come off, and has never developed any sharp edges that make it hard to play with.
It has never smelled or gotten slimy. It has never triggered resource guarding with him, but he likes it enough that presenting it to him will often get him to settle down and chew when he is in a rambunctious mood. Its size and shape allows him to hold the textured Y end with his paws while chewing on the smooth end.
All in all a fantastic toy!
