It is impossible for me to tell you at this stage the correct answer because of several reasons eg a Corgi cross at 40 pounds could be as skinny as due to the 'cross' part of the Corgi. Likewise I do not know what a 20 pound pure bred Corgi represents - a small structured Corgi, a very young Corgi ? All things been equal, the best way to go is using the feeding instructions on the packet/bag of food. But then is that all you feed your dogs. My Taylor gets three quarters of a cup per day of Hills Science whereas the bag instructions says upwards of 2 standard cups for a dog of his weight. - of course I have supplements to go with the dry food. If Taylor was overweight he would only get a daily meal equating to a cup of food.
