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. Nature’s Own 12″ Arthro-Moo is slowly dried to lock in all-natural flavors your dog enjoys.  As this is from grass-fed free-range cattle, it is a healthy alternative to corn fed beef products.
