It really depends on what KIND of food you are feeding. We feed Frosty Pedigree, which is pretty cheap and full of fillers, so he gets 2-3 cups a day depending on how many table scraps he gets, but Frosty is also a HUGE cardigan who weighs about 37 lbs. I know people feeding on higher quality food such as Wellness feed as little as 2/3 cup per day. With Frosty we just fed him the amount the breeder was feeding him, then adjusted it up or down over the weeks as he gained or lost weight. We found his ideal amount after 2-3 months of adjustments. Here are a couple discussions about food that might help. Good luck!!
we give our dogs science diet. Jacques is 24.5 pounds and he is fit and looks great, and gets a lot of activity.
Thanks for the responses guys :)
Ella is a 22lb female and gets 1 cup of Taste of the Wild a day (1/2 cup in morning, 1/2 cup for dinner). Corgis are such piggies when it comes to food, it really is best to split up the food into a few meals. Two meals works best for us, but I've heard some people even split it into 3 meals.
Easiest way is to decide on a game plan, X amount of food at Y time and Z time. Then monitor your corgi over a few weeks and see if the weight is going up/going down. Then adjust as needed.
I feed Iam's Lamb and Rice, about 360 cal/cup.
One gets half a cup twice a day (one cup total). He's a big, big male Pem (13.5 inch at the shoulder, over the standard) and his ideal weight is about 35 pounds. He was down to 33 and looked ribby to me.
The other was getting the same but she "blossomed" from 28 pounds up to 30 so now she's getting 1/3 cup twice a day (2/3 cup total).
I keep three measuring scoops in the tin: 1/4 c, 1/3 c, and 1/2 c. If they get extra treats or add-ins in the food, they each get bumped down a size for the evening meal, so Jack would get 1/3 c in PM and Maddie 1/4 c in PM. And I make sure the cups are level; a slightly heaped 1/4 c is actually a full 1/3 cup.
