How much does the second dog eat? ** The second dog eats 26 pounds a week because 13 x 2 = <<13*2=26>>26
How much do the dogs eat in total? ** In total they eat 45 pounds because 3 x 15 = <<3*15=45>>45
How much does the third dog eat? ** The third dog eats 6 pounds a week because 45 - 13 - 26 = <<45-13-26=6>>6
