The services of a New Zealand based animal food nutritionalist, Ms Jenny Anderson, were contracted to formulate a range of products, covering growth (puppy) adult maintenance, and active (working). The specifications called for New Zealand sourced raw materials, from the human food chain where possible. The product was to be wheat free, G.E. free, and completely natural. New Zealand sourced raw materials are preferred as there are no G.E. grains grown here, and the stock from which muscle meat is obtained are grass fed, not G.E. modified grain fed, or steroid fed as happens in some overseas countries. Also there is no foot and mouth, or mad cow disease in this country. The specifications have been analyzed by Massey University to confirm that they meet AAFCO requirements.
