Canine Nutrition is a compendium of magazine columns and articles published in the last 10 years. They focus on nutrition as it relates to performance, lifestages, medical considerations, safety and ethical issues. The magazeins in which the columns/articles originally appeared have largely gone out of business, making the articles difficult to access, even on the web. After being contacted by dog enthusiasts for copies of various articles, Smith decided to compile them into an e-book so the information would be easily accessible, particularly the articles dealing with nutrition and various canine maladies.
