1 According to The Dog Food Project, dog food will cost $160-$250 per year for a moderately active mid-sized dog. 2  The overall average price per year is $100-$300. 3  This price largely depends on the size of the dog and the quality of the dog food. Therefore, the higher quality of the food, the longer it will last. 2  A wellness type of dog food that is recommended for dogs that are either on a diet or need a special blend formula can cost anywhere from $23 to $55 per bag.
Find out how much you will have to feed your dog every day based on your dog's weight. 3 Divideâ¦ the amount in the bag by the amount you will feed your dog each day. The result is the number of days your dog food should last. Example: 100 pound dog, feed 4 cups twice a day, or 8 cups. The bag is 40 lbs. One pound of dry dog food averages about 2.5 cups. 8 / 2.5 = 3.2 pounds of food a day. 40 / 3.2 = 12.5 days of food.
