The general rule of paw is that for dry dog food, there's approximately:

  • 17.6 cups in a 4.4-lb. bag of kibble;
  • 20 cups in a 5-lb. bag;
  • 52 cups in a 13-lb. bag, and 
  • 100 cups in a 25-lb bag.

To do it yourself: There's approximately four cups in every pound of kibble dog food.

To figure out how often to set your subscription order, consult the feeding guide as to how many cups by brand your pup should eat per day. Then calculate the delivery dates from there on the site's system.
