Growing and consumption of rice has been a major agricultural concern, due to the potential for arsenic (As) uptake when rice is grown in flooded and arsenic rich fields. Currently, researchers are working on discovering ways to mitigate As uptake in rice by studying various water management strategies as well as genetically modifying rice to resist As uptake. Research in these areas neglect to address products that are made from rice that could  possibly be contaminated with As, such as dog food. In this study, 0.25 g samples of dry mass were taken from seven different dog foods, digested, by means of nitric digestion, and were analyzed using an Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) to determine how much As and cadmium (Cd) were present. The seven dog foods that were tested were Hill’s Science, Dr. Tim’s, EconoMax, Rachael Ray, Iams, Canidae, and Pedigree. Our results showed that Rachael Ray had the most As present (234.6±43.8 ?g/kg), Pedigree had the least amount of As present (37.63±1.38 ?g/kg), Canidae had the most Cd present (3137±89 ?g/kg), and Hill’s Science had the least amount of Cd present (47.87±2.43 ?g/kg).<br/>
