According to ingredients, lamb meal (or by products) + cereal grain (LG-food), fish meal (or by products) + cereal grain (FG-food), chicken meal (or by products) + cereal grain (CG-food), and animal by-products + grain-free (GFree-food) (with potato or tapioca) were selected equal numbers for E-food and P-foods. Total aflatoxin was not detected in the Gfree-dog foods and the FG-dog foods. The total aflatoxin concentrations of P-food and E-food were 1.30 ppb and 1.98 ppb in DM, respectively (P = 0.154). The fumonisin-B1 was detected in 10% of P-foods and 70% of E-foods (P < 0.001). The fumonisin-B1 concentration in GFree-food of dog was lower than those of other dog foods (P < 0.05). The highest fumonisin-B1 concentration of dog foods was in E-food of CG-food (3107 ppb in DM). The zearalenone concentration of GFree-food was lower than those of LG-food, FG-food and CG-food (P < 0.05). As a result, the total mycotoxins concentration of GFree-food (106 ppb in DM) were lower than those of other dog foods. The total mycotoxin, total aflatoxin, ochratoxin-A and fumonisin-B1 concentration of E-food were higher than those of P-foods. The highest total mycotoxin concentration was in the E-food classes of CG-food. Therefore, zearalenone concentration of P-food was higher than that of E-food.Highlights The total mycotoxin, total aflatoxin, ochratoxin-A and fumonisin-B1 concentration of the economic class dog food were higher than those of the premium class dog food. The highest total mycotoxin concentration was in the economic class dog food with chicken + grain. Ochratoxin-A has not been detected in any of the premium class dog foods. Economic class of grain-free dog foods contained very low concentrations of fumonisin-B1 and zearelenone mycotoxins, while premium class of they contained none.
