100% Chicken Legs. More of a substantial poultry bone, therefore better suiter to large/ medium breeds. Dogs should always be supervised when eating raw bones, and stools monitored to judge if the bone content of a dogs diet is sufficient (If your pet has very hard stool or white/grey stool, you have feed too much bone. Provide boneless meals for the next day or two to balance out the amount of bone previously fed. Once stools have returned back to normal, continue your normal meal routine).
