Puppies should eat a Variety of Proteins and Various Models like the PMR, BARF and Green Tripe Blends. Puppies need more bone than the typical 80/10/10 blends so we have created the PMR blends. These blends have 12-13% REAL ground bone (not bone meal or plant based calcium) and 15% REAL organs. 

However you can feed the 80/10/10 Blends as well and add duck heads, duck feet, chicken feet, turkey necks or any consumable bone to the to increase the bone content.
