The aim of this study determined the concentrations of total aflatoxin, ochratoxin-A, fumonisin-B1 and zearalenone in 40 different extruded dry type from premium (or with high price) (P-food) (n = 20) and economic (or with low price) (E-food) (n = 20) class foods with different nutritional content. 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.
