This natural dog food diet was designed to cater to adult dogs of all breeds and sizes. Zeal is ideal for sensitive dogs that need a grain and gluten free dog food or who may have a sensitivity to the more popular protein sources, such as poultry or beef. Zeal is naturally low-carb, with just 36.4% carbohydrates. Low carb diets are often indicated as part of a holistic approach to cancer recovery. Zeal is made with Ethoxyquin-free line-caught Haddock, wild Whiting and wild Salmon. Our Icelandic Haddock is wild caught using a line and hook, in the cold clean waters off the coast of Iceland. Our Blue Whiting is wild-caught in the waters of Scandinavia and the Arctic. It is one of the most abundant fish stocks in the semi-pelagic water masses of the northeast. Like all of our diets, its 100% human-grade, made in the USA, and does not contain corn, soy, rice, beet pulp or wheat. Just add water for a fresh, wholesome and human grade meal.
