Bone broth ice cubes are home made. They are made from chicken wings and beef rib bone and a selection of vegetable, cooked for 48hrs and the juices are then taken from the broth and made into ice cubes for your convenience. To feed to your dog just pick out a few and add hot water to melt the ice cubes, then add to your dogs food or give as a juicy treat. The broth is full of goodness and vitamins and minerals. They will just lap it up.
