Our Large Marrow Chews are the medium size chew done again. So they are basically double thickness. We let them dry once, and then we do the process all over again.
Bone Marrow Chews are made from dried bone marrow. We boil the bones to collect all the bone marrow, we then dry it for 3 weeks to turn it from liquid marrow to a hard chew. Awesome dental chews and highly nutratious as they are full of bone marrow goodness.
