Key Takeaways
- Pembroke and Cardigan Welsh Corgis are separate breeds with different weight ranges—Pembrokes typically weigh 25-30 lbs while Cardigans weigh 25-38 lbs, so using the wrong breed chart can cause unnecessary health concerns.
- A 6-month-old Pembroke puppy is usually around 82% of their eventual adult weight, providing a useful growth projection tool, while Cardigans continue growing until 18-24 months rather than stopping at 12 months.
- Weight numbers alone are insufficient for health assessment; instead check body condition by feeling ribs easily under light fat, looking for a visible waist from above, and observing an upward belly tuck from the side.
- Adult Pembrokes need approximately 600-800 daily calories while Cardigans need 700-950 calories; measure meals with an actual cup, count treats as part of daily totals, and use portion-controlled services to prevent weight gain.
- Corgis' unique long bodies and short legs mean extra weight strains their spine and joints significantly, increasing risk of serious back problems like IVDD, making weight management especially critical for this breed.
- Use weight charts as general reference guides rather than strict targets; track weight trends over weeks and months on the same scale, and consult your vet for sudden weight loss, rapid gain, or unusual growth patterns.
If you've ever typed "corgi weight chart" into Google at 11pm while your pup snoozes on your feet, you're in good company. Every corgi owner hits that moment of wondering if their dog is on track, especially since corgis have such a distinct, low-slung build. The tricky part is that "corgi" actually covers two different breeds, and mixing up their charts can leave you worried over nothing, or missing something worth a vet visit.
In this guide, we'll break down what a healthy Pembroke Welsh Corgi and Cardigan Welsh Corgi typically weigh at different ages, why the numbers differ between the two breeds, and how to use a weight chart the smart way. Whether you're a brand new corgi parent, a longtime owner, or just someone who loves following corgis online, this one's for you. Let's dig in.
Pembroke vs. Cardigan: Why One Chart Doesn't Fit Both
Here's something a lot of new owners don't realize: Pembroke Welsh Corgis and Cardigan Welsh Corgis are two separate breeds, not just two versions of the same dog. They share that iconic short-legged, long-back silhouette, but their bodies are built a little differently, and that shows up on the scale.
Pembrokes tend to be more compact overall, while Cardigans generally have a longer body and heavier bone structure. If you're not sure which one your pup is, our guide on how to tell Pembroke vs Cardigan Corgi apart can help you spot the differences, from tails to ear shape to overall frame.
Why does this matter for a weight chart? Because comparing your Cardigan to Pembroke averages (or vice versa) can make a perfectly healthy dog look too heavy or too light. Always check the chart that matches your dog's actual breed.
Pembroke Welsh Corgi Weight Chart by Age
Pembrokes are the more commonly seen corgi, thanks in part to their fame from royal circles and social media. Adult Pembrokes typically land in the 25 to 30 pound range, though healthy dogs can fall outside this window depending on genetics and build.
Here's a general look at how Pembroke puppies grow over their first year and a half:
Age | Male Weight (approx.) | Female Weight (approx.) |
|---|---|---|
8 weeks | 4–6 lb | 4–6 lb |
3 months | 10–13 lb | 9–12 lb |
6 months | 18–22 lb | 15–18 lb |
12 months | 28–30 lb | 24–27 lb |
18 months (adult) | 25–30 lb | 21–26 lb |
Keep in mind these numbers are estimates pulled from general growth patterns, not hard rules. Some healthy Pembrokes will sit a pound or two above or below these ranges their whole lives. One helpful pattern to know: a 6-month-old Pembroke puppy is usually around 82% of their eventual adult weight, which gives you a rough idea of where they're headed.
Cardigan Welsh Corgi Weight Chart by Age
Cardigans are the older of the two corgi breeds, and they run noticeably larger and longer-bodied than Pembrokes. Adult Cardigans typically weigh between 25 and 38 pounds, with males usually landing on the heavier end.
Age | Male Weight (approx.) | Female Weight (approx.) |
|---|---|---|
8 weeks | 5–7 lb | 4–6 lb |
3 months | 12–15 lb | 10–13 lb |
6 months | 22–26 lb | 18–22 lb |
12 months | 34–37 lb | 28–32 lb |
24 months (adult) | 30–38 lb | 25–34 lb |
Notice that Cardigans keep filling out longer than Pembrokes, often not settling into their final adult weight until somewhere between 18 and 24 months. If your Cardigan is still gaining steadily past their first birthday, that's usually completely normal rather than a red flag.
When Do Corgis Stop Growing?
This is one of the most common questions we hear, and the honest answer depends on which breed you have.
- Pembroke Welsh Corgis generally reach most of their adult height and weight by around 12 months old.
- Many Pembrokes continue adding muscle and filling out their chest and body condition until about 14 to 18 months.
- Cardigan Welsh Corgis tend to grow for longer, often not finishing up until 18 to 24 months.
- Individual dogs vary based on genetics, litter size, spay/neuter timing, and overall health, so treat these as general windows, not deadlines.

Weight Numbers Are Only Half the Story
Here's the honest truth: a weight chart is a helpful starting point, but it's not the whole picture. Two corgis can weigh exactly the same and have completely different body conditions, one lean and fit, the other carrying extra padding. That's because weight alone doesn't tell you how that weight is distributed.
Instead of obsessing over the exact pound number, vets and experienced owners recommend checking your corgi's body condition directly. Here's what to look for:
- Ribs: You should be able to feel your corgi's ribs easily under a thin layer of fat, without pressing hard.
- Waist: Looking down from above, there should be a visible narrowing behind the ribs, not a straight line from shoulders to hips.
- Tuck: From the side, your corgi's belly should tuck upward slightly behind the ribcage rather than hanging level or sagging.
- Energy and mobility: A healthy weight corgi moves comfortably and doesn't tire out unusually fast on normal walks.
If you're doing this check and something feels off, that's exactly the kind of thing worth mentioning at your corgi's next vet visit, since a hands-on exam beats guessing every time.
Why Corgis Are Prone to Packing on Pounds
Let's be real: corgis are famous for their food motivation. Those big ears and pleading eyes have talked plenty of owners into "just one more treat." Combine that with their short legs and long body, and extra weight shows up fast and puts real strain on their joints and spine.
This matters even more for corgis specifically because of their unique build. If you want to understand why spinal health is such a big deal for this breed, our piece on why corgis are so prone to IVDD in dogs explains the connection between body weight, back length, and disc health.
A few practical habits that help keep weight in check:
- Measure meals with an actual measuring cup instead of eyeballing it.
- Count treats as part of the daily calorie total, not extras.
- Choose lower-calorie training treats for frequent training sessions.
- Stick to a consistent daily walk or play routine, even in bad weather.
Choosing the right food also makes a real difference here. If you're not sure where to start, check out our roundup of the best dog food picks for corgis in 2026 for options that support a healthy weight without sacrificing nutrition. Many corgi owners have also had good results with fresh, portion-controlled meal services like Sundays for Dogs (get 50% off your first order), which can take the guesswork out of measuring calories accurately.
How Many Calories Does a Corgi Actually Need?
Calorie needs vary based on age, activity level, and whether your corgi is spayed or neutered, but general estimates can help you get in the right ballpark.
Corgi Type | Estimated Daily Calories |
|---|---|
Adult Pembroke Welsh Corgi | 600–800 kcal |
Adult Cardigan Welsh Corgi | 700–950 kcal |
These ranges assume a moderately active adult dog at a healthy weight. A less active senior corgi will need fewer calories, while a young, high-energy dog may need more. Your vet can help you land on a more precise number based on your individual dog's body condition and lifestyle.
Using a Corgi Weight Chart the Smart Way
A weight chart works best as a general reference point, not a strict target to hit. Here's how to actually put one to good use:
- Weigh consistently. Use the same scale at roughly the same time of day for the most accurate comparisons over time.
- Track the trend, not just one number. A single weigh-in matters less than whether your corgi is trending up, down, or holding steady over weeks and months.
- Compare against the correct breed chart. Pembroke and Cardigan ranges are different, so make sure you're using the right one.
- Pair the number with a body check. Feel for ribs and check for a waist and tuck alongside the scale reading.
- Loop in your vet for anything unusual. Sudden weight loss, rapid gain, or a puppy who seems way outside the expected range deserves a professional look.
If your corgi is a puppy still growing, a growth chart or online calculator can give you a rough projection, but remember these tools are estimates based on averages, not promises about your individual dog.
Signs It's Time to Call the Vet
Most weight fluctuations in corgis are perfectly normal, but a few signs are worth a vet check rather than a wait-and-see approach:
- Noticeable weight loss without a change in diet or activity
- Rapid weight gain over a short period
- A puppy who seems significantly smaller or larger than littermates or breed averages
- Reduced energy, reluctance to walk, or stiffness alongside weight changes
- Difficulty feeling the ribs even with firm, gentle pressure
None of these automatically mean something serious is going on, but they're exactly the kind of pattern your vet is trained to sort out. Trust your gut here. You know your corgi's normal better than any chart ever could.
Wrapping Up: Let the Chart Guide, Not Dictate
A corgi weight chart is a genuinely useful tool, especially when you're raising a puppy or keeping an eye on your adult dog's health over the years. But the real magic happens when you combine those numbers with hands-on body checks, a good diet, and regular vet visits. Your corgi's ideal weight is personal to them, not just a number pulled from an average.
