Questions? Answered.

How long will one last?

Marrow bones are one of our longest-lasting chews — typically they'll work on the outside for thirty minutes than start working on the marrow. We suggest breaking up into multiple chewing sessions and taking away after 30 minutes or if your dog gets too aggressive.

Why pay more than a traditional rawhide chew?

Because you can pronounce every ingredient — one, actually. No bleach, dyes, glue, or mystery rawhide. Just clean, single-ingredient bison, slow-roasted in Colorado.

Is it safe for my dog?

Marrow bones are a dense, natural bone — best for moderate chewers, always under supervision. We slow roast ours for over 40 hours at low temperatures with moisture throughtout the whole process to prevent breakage or splintering.

Which size should I choose?

2" for puppies, small dogs & light chewers; 4-5" for medium dogs; 6-8" for large breeds & power chewers.

What's actually in it?

One ingredient: bison marrow bone. No salt, sugar, smoke, rubs, or preservatives.

My dog has allergies — is bison okay?

Bison is a novel protein and a great option for dogs sensitive to beef or chicken.

How do I store it, and where is it made?

Store in a cool, dry place; refrigerate any exposed marrow and use within a few days. Made in Colorado from local, grass-fed bison.
