An all natural Nature’s Own 12″ Arthro-Moo Stick is a great chew with a purpose. It is a 12″ all natural angus beef esophagus from free range cattle out of Brazil. No hormones or antibiotics. The Nature’s Own 12″ Arthro-Moo is slow dried to lock in all natural flavours your dog enjoys. As this is from grassfed free range cattle, it is a healthy alternative to corn fed beef products. This chew comes from a human grade facility in Brazil that meets and exceeds USDA and CFIA standards.
