The quality of dog diets depends on adequate ingredients capable of providing optimal nutrition and free of contaminants, for promoting long-term health. Trace elements in 95 samples of dry food for dog puppies (n = 32) and adults (n = 63) of various brands were measured using instrumental neutron activation analysis (INAA). The mass fractions of most elements were within the permissible limits for dogs. Aluminum, antimony, and uranium presented fairly high levels in some samples, which may imply health risks. Aluminum mass fractions ranged from <21 to 11,900 mg/kg, in same brand, super-premium dog food. Antimony mass fractions ranged up to 5.14 mg/kg, with the highest values measured in six samples of dog food from the same producer. The mass fractions of uranium was found up to 4 mg/kg in commercial brands from five different producers.


This website is a labor of love brought to you by the volunteers at Paws For Change. Our goal is to put together links to published research studies, articles, books, and other media which have influenced our approach to feeding diets that include fresh and raw foods. We encourage everyone to research further to gain a fuller understanding of any controversies or debates involved. It is a growing collection and we welcome you to use the submission form below if you have studies you'd like to suggest be included here.
