Whole beef marrow bones.
Per Florida Law this is sold as "Not for Human Consumption, Pet Food Only"
Marrow bones have little to no meat and are filled with marrow which make for a delicious, nutrient dense broth for your pets. Use for making stock or broth.
When cooked together with soup bones your pet not only gets a rich broth for soup but also the added benefits of the meat from the soup bones.
To make soup for your pets: add marrow bones and soup bones to pot with enough water to cover. Cook soup bones until meat falls off the bones, about 4 hours. At this point you can discard the bones and finish making your soup as described below or take the meat off the bones, set meat aside. Put the bones back into the soup pot to continue to cook for broth making. Once you feel like the bones have been cooked down enough for your soup base, discard the bones and add the meat back in, along with any veggies, seasonings, canned tomatoes, etc and you will have a delicious, nourishing meal for your pets.
