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.
This varies depending on your dog's size and activity level. Two cups equals one pound of dog food, which equals 30 pounds of food per month. The typical mid-range brand bag of kibble (Purina, Alpo, or Iams for example) costs about $35 per 30 pound bag. So, the cost per month would be roughly $35 per month.
