Dried Wild Alaska salmon with lots of meats in them. No artificial preservatives, substitutions, artificial colorings, flavorings or seasonings and no treatments. Resourced and dehydrated in-house as Drool Central only does. Keep sealed in a cool dry place out of moisture. Consume right away. That wouldn't be an issue because your dogs will go crazy for these. Break them into little pieces. Lots of omega 3 fatty acid to make your pups' skin and coat shiny and soft.
