Pug.

RKC: bred purely as companions, not for work. AKC page: once the companion of Chinese emperors and later the mascot of the House of Orange. FCI 253: utilization companion dog; China, patronage Great Britain. UKC: a happy, even-tempered companion; probably descended from the Orient, a smooth-coated, longer-legged type of Pekingese. Wikipedia: companions to ruling families; says Pugs were used by the military to track animals and people and as guard dogs in Europe (unreferenced on the page read)..

Breed sets the odds. The parents set the dog. Every number here shows its source, its spread and how sure we are. Nothing on this page is a prediction about one dog.

The body

What the breed is built like. Registry standards give an ideal, not a range.

Height at the shoulder

10 to 13 in

Breed clubAKC

Single registry source, and it is a page band, not a standard. Square proportion is the standard's requirement, so height tracks length.

Weight

13.9 to 18 lb

Breed clubAKC breed standard, 2008

AKC and UKC print the same range; FCI converts to 13.9 to 17.9 lb. A range, not a single ideal, so center is blank. Wikipedia flags obesity as a Pug problem (see top_disorders), and the RKC notes Pugs can be food-motivated to the point of overeating.

Coat

AKC: fine, smooth, soft, short, glossy; fawn or black, fawn with a clear black mask, ears, cheek moles, thumb mark or diamond on the forehead and a black back trace; any other colour is a disqualification. UKC: silver, apricot, fawn or black; hard or woolly coat is a fault; albinism disqualifies. FCI 253: silver, apricot, fawn or black. RKC: will not register merle Pugs, including imports, because the merle gene carries a risk of impaired hearing and sight.

Breed clubAKC breed standard, 2008

AKC lists fawn and black only; UKC and FCI add silver and apricot. Both stand.

Shedding

RKC: sheds; known to shed considerably despite the short coat; benefits from a weekly groom. AKC page: shedding level 4 of 5.

Breed clubThe Royal Kennel Club

Registry bands; no study opened.

Heat tolerance

1 of 5 · RKC: the Pug's flat-faced structure limits tolerance for heat, humidity and strenuous activity; exercise should be gentle and moderated in warm weather; not to be over-exercised in hot weather because of brachycephalic airways. Coat: AKC and UKC standards, fine, smooth, soft, short and glossy. UKC lists a muzzle so short and blunt as to affect breathing, and excessive nose wrinkle that inhibits breathing, as eliminating faults; FCI 253 calls pinched nostrils and heavy over-nose wrinkle unacceptable. Wikipedia: brachycephaly can cause hyperthermia, from not being able to cool by panting; several airlines banned or restricted brachycephalic breeds in cargo after deaths in heat. Pug Dog Club of America: not all Pugs are affected by BOAS, but the condition can develop as a dog ages.

DerivedThe Royal Kennel Club

Derived: a short single coat alone would sit at 5, but the RKC states plainly that the Pug's flat-faced structure limits tolerance for heat and that it must not be over-exercised in hot weather. Placed at 1, the same rung as the Bulldog, whose RKC statement is equally plain (the scale's 1 is written for heavy coat plus brachycephaly; these breeds have the brachycephaly, not the heavy coat). The step down is the registry's statement, not a heat-illness study.

How long they live, and what they costSources differ

Two numbers, two measures. Median lifespan: in a large sample of this breed, the age by which half had died; read it as the typical lifespan (UK, 2024, 584,734 dogs). Life expectancy at birth: how many years a newborn of this breed is expected to live, worked from the death rates at every age in UK veterinary records, the same life-table method used for people (VetCompass, 2022). It runs lower because every early death pulls the average down and because it comes from clinics, not registries. KENAI leads with the median and shows the other beside it. Neither is averaged.

Median lifespan

11.6 years (11.4 to 11.8)

MeasuredMcMillan KM, 2024

McMillan et al. 2024 / Dogs Trust table. UK population. A different measure from the life expectancy at birth in Teng 2022 (7.65 years, next row), which counts every death from birth in one UK veterinary-care sample; the two disagree sharply for the Pug and both are shown, never averaged. The AKC page 13 to 15 year band is a band, not a median, and is not used. The Japanese figure is Wikipedia's summary of a cemetery sample that was not opened.

Life expectancy at birth

7.7 years (7.0 to 8.2)

MeasuredTeng K.T., 2022

Sources differ with median_lifespan_yr: life expectancy at birth from VetCompass life tables (counts every death, including young ones) against median age at death in a registry-linked sample. A short life expectancy for the breed, shown plainly (in this batch only the English Bulldog, 7.39 years, is lower). Small sample (197). Teng 2022 Table 3 read at the nature.com table page. Wikipedia sets it against a general UK average of 11.23 years; that comparison figure was not read in the paper here.

The dog at home

What the breed asks of a day. The first thing most homes get wrong.

Exercise need

RKC: up to 1 hour per day, split into shorter sessions; should not be over-exercised, particularly in hot weather, because of the flat-faced airways. Suits a flat or apartment; small to medium garden.

Breed clubThe Royal Kennel Club

RKC is a UK registry band, not a study; mapped by the library rule (up to 1 hour = 60).

Exercise need

RKC: modest exercise needs; regular short walks and play; flat-faced structure limits tolerance for heat, humidity and strenuous activity, so keep exercise gentle and moderated in warm weather; can be food-motivated to the point of overeating if under-stimulated. AKC page bands: energy level 3 of 5, mental stimulation needs 3 of 5, playfulness 5 of 5, barking level 1 of 5. FCI 253 temperament: great charm, dignity and intelligence; even-tempered, happy and lively. RKC: dislikes long periods alone and can be prone to separation anxiety.

Breed clubThe Royal Kennel Club

AKC bands are not mapped to minutes; RKC supplies the minutes figure. The separation line is the RKC's own wording, not a C-BARQ mean.

Energy

3 of 5

Breed clubAKC

AKC breed page trait score, 1 to 5: a breed-club tendency, never a measurement.

Grooming load

2 of 5 · RKC: grooming once a week; short coat; sheds, and 'known to shed considerably'. AKC page: coat grooming frequency 2 of 5, shedding 4 of 5. AKC and UKC standards: fine, smooth, soft, short, glossy coat. FCI 253: any stripping or trimming that alters the coat should be penalised. RKC health text: skin folds in flat-faced breeds make a warm, moist place where bacteria and yeast grow, so fold care is extra coat work.

Breed clubThe Royal Kennel Club

RKC band mapped by the library rule (once a week = 2). Low coat work, high shedding, and fold cleaning that the band does not capture.

The work

What it was built to do in the field, and what a test or trial asks of it.

Role

RKC: bred purely as companions, not for work. AKC page: once the companion of Chinese emperors and later the mascot of the House of Orange. FCI 253: utilization companion dog; China, patronage Great Britain. UKC: a happy, even-tempered companion; probably descended from the Orient, a smooth-coated, longer-legged type of Pekingese. Wikipedia: companions to ruling families; says Pugs were used by the military to track animals and people and as guard dogs in Europe (unreferenced on the page read).

Breed clubThe Royal Kennel Club

A companion breed. The military and guard use is a single editorial line.

How common the problems are

Evaluated dogs skew toward breeding stock; the numbers are still the best there are.

Hip dysplasia

72.7% · 1,282 OFA hip evaluations, current all-data, accessed Oct 9 2026; 72.7% dysplastic (mild 41.0, moderate 26.6, severe 5.1), only 25.7% normal. OFA rank 2 (second-highest rate among the breeds listed). Pug Dog Club of America: many Pugs are affected but most lead normal, healthy lives with it, unlike large and giant breeds that need surgery to get around. Wikipedia: a 2010 OFA survey found nearly 64% affected, then second of 157 breeds.

MeasuredOrthopedic Foundation for Animals

OFA's own breed statistics. OFA-evaluated dogs skew toward breeding stock (owners and breeders submit films, and poor results are less likely to be submitted), so this is not the rate across all dogs of the breed; the true population rate is not known. OFA rank 1 = highest rate among the breeds listed. Under-reporting also applies. The rate is far above the raw numbers for most breeds and is shown plainly. The club's comment is a breed-club statement, not a study.

Elbow dysplasia

35.9% · 393 OFA elbow evaluations, current all-data, accessed Oct 9 2026; 35.9% abnormal (grade 1 24.2, grade 2 10.7, grade 3 1.0), 63.9% normal. OFA rank 5.

Most common disorders

RKC: a flat-faced (brachycephalic) breed, so at higher risk of breathing difficulty (BOAS), skin-fold infection, dental crowding and eye problems; Breed Watch category 3. RKC good-practice screening: BOAS (KC Respiratory Function Grading scheme) and the BVA/KC/ISDS eye scheme; best practice adds the PDE DNA test and BVA/KC hip scoring. Pug Dog Club of America: Pug dog encephalitis (PDE/NME), Pug myelopathy (rear-limb ataxia), luxating patellas, hip dysplasia, BOAS. Wikipedia: eye injury and dry eye; UK work finds Pugs three times more likely to become obese, with one in five diagnosed obese in a year; NME affects roughly 1 to 2% of Pugs; hemivertebrae; high rates of caesarean birth; demodicosis (1% prevalence against 0.17% average in a British study).

How to read this page

Every value carries a label. Measured means peer-reviewed data on many dogs. Studied means peer-reviewed, smaller or indirect. Breed club means a club or registry states it. Editorial means expert opinion with no measurement behind it. Where two good sources disagree, both are shown and neither is averaged.

Published when the entry rests on the best information available from no fewer than three independent sources, checked by a second pass that did not write it. 8 sources on this page. Found something wrong? Tell us and the correction is logged with its date.
