Corgi Weight by Age: Pembroke vs Cardigan Size and Healthy Growth

“How much should my corgi weigh?” is one of the most common questions we see. The honest answer has two parts: the breed standards give an adult size range for each corgi breed, and your vet tracks your own puppy’s growth. Here is how the two fit together, and why we do not print a month-by-month puppy weight chart.

Two corgi breeds, two size ranges

Pembroke and Cardigan Welsh Corgis are separate breeds, and their official breed standards describe different sizes:

Breed standard	Height at the withers	Weight
Pembroke Welsh Corgi	10 to 12 inches	Not exceeding 30 lb (dogs) and 28 lb (bitches); show-condition dogs preferably about 27 lb, bitches about 25 lb
Cardigan Welsh Corgi	10½ to 12½ inches	Ideally 30 to 38 lb (dogs) and 25 to 34 lb (bitches)

Sources: the AKC Pembroke standard and the AKC Cardigan standard. The AKC breed pages summarize the same ranges.

These numbers describe the show standard. They are not a feeding goal, and they do not mean every pet corgi should weigh exactly that much. The Pembroke standard itself says weight is “in proportion to size,” and the Cardigan standard says overall balance matters more than absolute size. A pet with a heavier or lighter frame can still be healthy, and a dog inside the range can still be overweight.

Why we do not give a monthly puppy-weight table

Many websites publish a table of “average corgi weight at 8 weeks, 12 weeks, 6 months.” We are not aware of a published, sourced growth chart built specifically for corgis, and an online table with no stated sample or method is not a clinical reference, even when its numbers are called averages. So we do not print one.

What exists is more useful. Research by Salt and colleagues developed growth charts from veterinary records, with separate curves by sex and by expected adult-size category. Your vet can choose a suitable chart, plot your puppy’s repeat weights and interpret the trend. A single weigh-in cannot tell you whether a puppy is growing well, and forcing a puppy onto the “middle” line is not the goal.

Keep a useful weight log

Ask your vet how often to weigh your puppy. Use the same reliable scale when you can, and write down the unit. If lifting your puppy is hard or unsafe, ask the clinic about weighing options. Bring the log, the food label and the amount you actually feed to appointments, along with notes about appetite, stool, comfort and energy.

Our free weight journal can hold your dated measurements on your own device. It does not predict adult size or label a weight as normal. It just keeps your records tidy for the vet.

Check body condition, not only the scale

The WSAVA body condition chart describes an ideal adult appearance as ribs you can feel without excess fat covering them, a waist behind the ribs when viewed from above, and an abdominal tuck when viewed from the side. A corgi’s thick double coat can hide the outline, so gentle hands-on checking matters more than a glance. Ask your vet to show you how to do it on your own dog.

Corgis are long and low, so ask your vet how your dog’s body condition relates to back and joint comfort and to the activity plan that suits your dog.

Feed for steady growth, not maximum growth

VCA Animal Hospitals describes an optimal growth rate as slow and steady, letting a puppy reach an ideal adult body condition while avoiding excess weight. It contrasts that with maximal growth, as fast as possible, usually from high-energy foods, overfeeding or free feeding, which it links to higher risks of skeletal deformities, obesity and a shortened life expectancy. VCA also says regular weigh-ins and body condition checks help keep a puppy on track. Follow the food label as a starting point and adjust with your vet based on body condition and growth, not on what an online chart says a puppy “should” weigh.

When to call your vet

Contact your veterinarian if your puppy is losing weight, is not gaining as expected, seems low on energy, has repeated vomiting or diarrhea, or has a belly that looks swollen. Weight and growth questions are health questions, so this guide is general education and not a substitute for a vet who has examined your dog.
