Wet or dry dog food ??.... Wet dog food has a density greater than water which is 8.34 lbs/gallon 60 liters is 60/3.786 = 15.85 gallons so if water the weight would be 8.34 x 15.85 = 132 lbs add say about 10% since dog food has some solids which means the 1.1 x 132 = 145 lbs Dry dog food has a bulk density of about half the weight of water so say about 4 lbs per gallon so 15.85 gallons x 4 = 63 lbs give or take a little depending on the dog food...
