An adult pug needs a complete food and, more than almost any other breed, carefully weighed portions: a neutered, moderately active pug of 7 kg needs about 304 kcal a day. The reason is in UK veterinary data: of the breeds studied, the pug is the one most prone to excess weight, the typical pug already weighs more than the ideal set by its breed standard, and, unlike the French Bulldog, extra weight in a pug also shows in how it breathes.
With a pug, the question that matters most is not which food but how much. It needs a complete food, of course, but what sets it apart from almost every other breed is how easily it puts on weight, and nearly everything that matters in its bowl follows from that: known calories, weighed portions and a regular hands-on check of its body condition.
The evidence comes from UK vet records collected by VetCompass, the Royal Veterinary College research programme. In a study of 22,333 dogs, the pug had the highest odds of being recorded as overweight of all the breeds analysed: about three times those of crossbreeds (OR 3.12), ahead of the Beagle (2.67) and the Golden Retriever (2.58). In a second study comparing 4,308 pugs with 21,835 other dogs, obesity was the breed's most common diagnosis: 17.4% of pugs against 6.9% of other dogs.
So yes, pugs get fat easily. And although pugs and French Bulldogs look alike, at the food bowl they are almost opposites. In a University of Cambridge study in which researchers examined 189 pugs and 214 French Bulldogs in person, 60.8% of the pugs were obese (a score of 7 or more on a 9-point scale), compared with 8.4% of the French Bulldogs. Same short muzzle, very different bowl.
The FCI breed standard gives an ideal weight of 6.3-8.1 kg, one range for dogs and bitches alike: you will often see separate figures for males and females, but the standard does not give them. It also contains two unusually blunt lines: a pug's “substance” must not be confused with overweight, and obesity is “highly undesirable”. The British standard, now the Royal Kennel Club's, goes further and calls obesity “unacceptable”. It has not always been so clear. In 2022 the VetCompass researchers criticised the line in the Kennel Club standard saying a pug should never appear “lean and leggy”, and suggested wording that rewards leanness instead. Today the word “lean” has gone, both from the British text updated in April 2025 and from the 2023 FCI one: only “leggy” remains.
Real pugs are heavier. In a VetCompass study of 746 adult pugs weighed at the vet, the median weight was 9.2 kg (9.9 kg for males, 8.2 kg for females) and more than half weighed 9 kg or more; in the later study of 4,308 pugs the median adult weight was 8.95 kg. Both are above the top of the standard. Read the scales with care, though: the VetCompass authors themselves point out that weight in kilos should not be confused with body condition, that is, with how much fat the dog is carrying.
That is why your eyes and hands matter more than the number. In the Cambridge study, where 85% of the pugs were not clinic cases but dogs volunteered by owners and breeders or seen at shows, the median body condition score was 7 out of 9, above ideal. In routine records, the VetCompass authors add, overweight is probably under-reported. On the WSAVA 9-point scale the ideal is 4-5: ribs easy to feel under a thin layer of fat, a visible waist from above and a tummy that tucks up when seen from the side. There is more on this in our guide to fat and overweight dogs.
The pug is one of the breeds most affected by brachycephalic obstructive airway syndrome (BOAS), the airway obstruction caused by a short muzzle: in VetCompass data it was diagnosed in 6.6% of pugs against 0.1% of other dogs. The main cause is anatomy, and no food changes that. But in the pug, unlike the French Bulldog, weight adds to the anatomy.
In the Cambridge study, breathing was measured objectively in 115 pugs by whole-body plethysmography, which gives an obstruction index from 0 to 100: each extra point of body condition was linked, on average, to an index 6.4 points higher. In French Bulldogs this link did not show up. And in the same model, a pug's weight in kilos was not linked to the index: its body condition was. A 2026 study of 49 pugs with BOAS, CT-scanned before surgery, suggests why: the more condition a pug carried, the more fat there was inside its tongue, and pugs with the most severe BOAS had more fat in the larynx area. Fat is not only laid down on the belly, but along the airway too.
Then there is the heat. In a study of more than 900,000 UK dogs, pugs had about three times the odds of heatstroke of Labradors; across all breeds, dogs at or above the average weight for their breed and sex had about 1.4 times the odds of lighter ones, and roughly one episode in seven was fatal. If your pug snores heavily, tires quickly or pants even at rest, that is one for your vet.
Stomachs, less than you might think. In a study of dogs having airway surgery for BOAS at a veterinary teaching hospital, drooling, regurgitation and vomiting were seen in 16% of 43 pugs against 93% of 43 French Bulldogs. In VetCompass data, vomiting and diarrhoea were only slightly more common than in other dogs (vomiting 4.5% vs 3.1%, diarrhoea 5.0% vs 3.8%). If your pug vomits often, talk to your vet before changing food.
Skin is a mixed picture: allergic skin disorders were recorded in 1.6% of pugs against 0.3% of other dogs, while atopic dermatitis was no more common (1.2% vs 1.1%). Few cases in absolute terms, and not all of them food-related. If your pug has recurring itching or digestive upsets, your vet can set up an elimination diet, using a protein the dog has never eaten, for at least 8 weeks: over that period more than 90% of dogs with a food reaction go into remission. Switching foods again and again only makes the diagnosis harder.
Is your pug allergic to chicken? Owners often ask, but we found no study showing that pugs react to chicken more than other dogs: in a review of dogs with proven food reactions, the most frequent culprits were beef, dairy, chicken and wheat.
Each Pappa Fresh recipe contains one meat and lists the percentage of every ingredient and the calories per 100 g on the label. With a pug, it pays to know exactly how many calories go into the bowl:
The richest recipe has roughly a quarter more calories than the lightest ones, so if you rotate recipes, weigh the portion for the one you are serving. If you would rather keep some kibble, the Mix plan covers half the ration: in that case halve the kibble too, or the calories simply add up. The recipes are cooked in the pouch and keep outside the fridge until opened; once opened, keep them in the fridge and use within 2-3 days. For a 7 kg pug one 400 g pouch lasts about 1.5 days.
A neutered, moderately active adult pug of 7 kg needs about 304 kcal a day: that is roughly 267 g of our Chicken recipe, or 224 g of the richer Beef. An entire pug burns more, about 380 kcal. The chart runs from 6 kg to 8 kg, roughly the breed standard's range (6.3-8.1 kg). The gap between the two figures (neutered / intact) matters: in the VetCompass overweight study, being neutered was one of the factors linked to extra weight, so neutering is the moment to recheck the portion rather than carry on as before.
If your pug weighs 9 or 10 kg, do not simply read off the portion for a dog of that weight: ask your vet what its ideal weight is first, because that is what the portion should be based on. That is also why our quiz asks for your dog's body condition as well as its weight, and takes it into account. For the general rules, see how much a dog should eat.
| Weight | Energy need (kcal/day) neutered / intact | Grams per day neutered / intact | Complete plan | Mix (½) |
|---|---|---|---|---|
| 6 kg | 271 / 339 | 238 g / 297 g | €4.41/day | €2.16/day |
| 7 kg | 304 / 380 | 267 g / 333 g | €4.93/day | €2.43/day |
| 8 kg | 336 / 421 | 295 g / 369 g | €5.45/day | €2.69/day |
Grams based on the Chicken recipe (114 kcal/100 g); with Beef, which is richer (136 kcal/100 g), you need about 16% less. Prices for a neutered dog.
Figures calculated with the same method as our quiz (FEM×K: maintenance energy adjusted for breed, activity, neutering and body condition). They are an estimate: take the quiz for your dog's exact plan, and talk to your vet about any health concern.
Two minutes: enter weight, age, activity and body condition to get the exact portion, with 30% off your first order.
A neutered, moderately active adult pug of 7 kg needs about 304 kcal a day; an entire pug needs about 380 kcal. At 8 kg, neutered, it is about 336 kcal. These are estimates for a dog at ideal weight: the exact figure also depends on activity and body condition.
For a neutered, moderately active adult pug of 7 kg, about 267 g a day of our wet Chicken recipe, or about 333 g if it is entire. Wet food contains more water than kibble, so for the same calories the portion in grams is roughly three times bigger: that is normal.
The FCI breed standard gives an ideal weight of 6.3-8.1 kg for males and females alike. In English vet records adult males had a median weight of 9.9 kg and females 8.2 kg, above the standard. Body shape matters more than the number: ribs you can feel without pressing and a visible waist from above, a score of 4-5 on the WSAVA 9-point scale.
Yes, more than any other breed in a UK study of 22,333 dogs: pugs had about three times the odds of being recorded as overweight compared with crossbreeds, and in a later study obesity was their most common diagnosis. To check your own pug, feel for the ribs and look for a waist from above: if you cannot feel the ribs without pressing, it is probably above ideal weight. Your vet can tell you whether the extra kilos are frame or fat.
Yes. In a study of more than 900,000 UK dogs, pugs had about three times the odds of heatstroke of Labradors, and, across all breeds, the odds were higher in dogs at or above the average weight for their breed. If your pug pants hard or struggles to recover after heat, call your vet straight away.
Not as a rule. Allergic skin disorders of any cause were recorded in 1.6% of pugs in UK vet records: more than in other dogs, but still few, and we found no study showing that pugs react to chicken more than other dogs do. In dogs in general, the ingredients most often behind proven food reactions are beef, dairy, chicken and wheat, in that order. Only an elimination diet supervised by your vet can tell. Turkey is poultry too, so if your pug has reacted to chicken, ask your vet before trying it.
