Freeze-Dried Treats Naturally healthy treats for dogs made from Norwegian Ocean White fish, these treats are freeze dried rather than cooked, a process that preserves all of the taste and nutrition of the magnificent fish. Why not try our fabulously fishy complete foods too. Our Freeze Dried Treats For Dogs are gluten and grain free, with no artificial preservatives or colourings added. These super-tasty snacks are also great as a training treat. Feed fish and see the difference.
