Boxer.

A working animal, not a gun dog. AKC: developed to serve as guard, working and companion dog; instinctively a hearing guard dog, alert and self-assured, with fearless courage if threatened. FCI 144: companion, guard and working dog, 'with working trial'; easy to train, with natural keenness and scent capability. UKC: virtually ignored until World War II, when it was brought into use as a military or police dog; a studied watchdog and defender. RKC: an excellent guard dog that has proved itself as a tracking dog and in the armed forces as a messenger and pack carrier. American Boxer Club (parent club): one of the first breeds selected in Germany for police training; used as guards and couriers in wartime and today as narcotics detectors, police dogs and in search and rescue, plus guide, hearing, seizure-alert and therapy work..

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

dogs 22 to 25 in · bitches 20.9 to 23.5 in

Breed clubAKC breed standard, 2005

No standard prints a single ideal, so center is blank; low (FCI) and high (AKC) span all three registries.

Weight

dogs 65 to 80 lb · bitches 55 lb

Breed clubAKC

Center is the FCI's printed approximate figure. No source prints a female range, so low and high are blank; a range worked out from the AKC's 'about 15 lb lighter' would be our arithmetic, not a source.

Coat

AKC: short, shiny, lying smooth and tight to the body; colors fawn and brindle (fawn from light tan to mahogany), white markings not over one-third of the coat; other colors and excess white disqualify. UKC: short, hard and shiny; fawn and brindle; white not over one-third. FCI 144: short, hard, glossy and close fitting; fawn or brindle with a black mask; white markings 'should not be discarded' but not over one-third. RKC: short coat.

Breed clubAKC breed standard, 2005

Shedding

RKC: sheds (yes). AKC breed page: shedding level 2 of 5. American Boxer Club (quoting AKC): seasonal shedding.

Breed clubThe Royal Kennel Club

Heat tolerance

4 of 5 · AKC: coat short, shiny, lying smooth and tight to the body. UKC: short, hard and shiny. FCI 144: short, hard, glossy and close fitting. Wikipedia (editorial) describes the skull as brachycephalic (broad and short, with a square muzzle).

DerivedAKC breed standard, 2005

Derived from the coat (a short, tight, single-layer coat on the 1-5 scale sits at 4 to 5). Held at 4 rather than 5 because the breed's short, blunt muzzle (the standards call the broad blunt muzzle 'the distinctive feature') argues against the top tier; no heat-illness study was opened, so this one-step adjustment is a judgement, flagged here.

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

11.3 years (11.3 to 11.5)

MeasuredMcMillan KM, 2024

Dogs Trust UK table from McMillan et al. 2024 (all-dog median 12.5 y in 584,734 dogs). Other measures, shown and not averaged: AKC breed page life expectancy band 10-12 years (a band, not a median); RKC band 'over 10 years'; Wikipedia (editorial) cites a 2005 Swedish insurance study in which 50% of Boxers had died by age 10 against 35% of all dogs.

Life expectancy at birth

10.0 years (9.8 to 10.2)

MeasuredTeng K.T., 2022

Sources differ with median_lifespan_yr: a different measure (life expectancy at birth from VetCompass life tables vs median age at death in a registry-linked sample) and a different sample; both shown, never averaged. Teng 2022 Table 3 read at the nature.com table page.

The dog at home

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

Exercise need

More than 2 hours per day (RKC band)

Breed clubThe Royal Kennel Club

RKC band mapped: more than 2 hours = 150. A floor, not a ceiling.

Exercise need

RKC: more than 2 hours per day; large house and large garden suit. American Boxer Club: high energy and very active, 'strong, quick, busy dogs who need plenty of exercise' who enjoy physical and mental challenges. AKC breed page: energy level 4 of 5, mental stimulation needs 4 of 5.

Energy

American Boxer Club: very active; strong, quick, busy dogs who need plenty of exercise. AKC breed page trait scores: energy level 4 of 5, playfulness 4, mental stimulation needs 4. Wikipedia (editorial): bright, energetic and playful; needs adequate exercise to prevent boredom-driven chewing.

The work

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

Role

A working animal, not a gun dog. AKC: developed to serve as guard, working and companion dog; instinctively a hearing guard dog, alert and self-assured, with fearless courage if threatened. FCI 144: companion, guard and working dog, 'with working trial'; easy to train, with natural keenness and scent capability. UKC: virtually ignored until World War II, when it was brought into use as a military or police dog; a studied watchdog and defender. RKC: an excellent guard dog that has proved itself as a tracking dog and in the armed forces as a messenger and pack carrier. American Boxer Club (parent club): one of the first breeds selected in Germany for police training; used as guards and couriers in wartime and today as narcotics detectors, police dogs and in search and rescue, plus guide, hearing, seizure-alert and therapy work.

Breed clubAKC breed standard, 2005

Primary game

Historic only; the Boxer is not a current hunting breed. FCI 144: the Brabant Bullenbeisser, the Boxer's immediate ancestor, was bred by huntsmen to seize the game put up by the hounds and hold it until the huntsman arrived, which is why the breed has a wide, strong jaw. RKC: the Bullenbeisser hunted bear, boar and deer in the 19th century. Wikipedia (editorial): the same three quarry.

Breed clubFCI Standard No. 144, 2008

Historic quarry of the ancestor breed, stated in the FCI history and the RKC page; neither says the modern Boxer is worked on game.

Field trial standard

No hunt test or field trial applies. FCI 144 lists the Boxer in Group 2, Section 2.1, 'with working trial'. The American Boxer Club lists Schutzhund and police work among the breed's activities and describes Schutzhund as testing the traits police-type work needs: desire to work, courage, intelligence, trainability, bond to the handler, perseverance, protective instinct and scenting ability.

Breed clubFCI Standard No. 144, 2008

The IGP/Schutzhund line is the parent club's description of the sport, not a Boxer pass rate; no breed-specific results were found.

How common the problems are

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

Hip dysplasia

12.6% · 12.6% dysplastic of 7,732 OFA hip evaluations on record (current all-data, accessed Oct 9 2026); 85.7% normal; mild 9.4%, moderate 2.8%, severe 0.4%; breed rank 103

MeasuredOrthopedic Foundation for Animals

Voluntary registry: affected dogs are under-reported and evaluated dogs skew toward breeding stock, so true prevalence in the wider population is higher. OFA rank 1 = highest rate among the breeds listed. Wikipedia (editorial) lists hip dysplasia among the breed's health issues.

Elbow dysplasia

1.1% · 1.1% abnormal of 1,795 OFA elbow evaluations on record (current all-data, accessed Oct 9 2026); 98.8% normal; grade 1 0.9%, grade 2 0.1%, grade 3 0.1%; breed rank 141

MeasuredOrthopedic Foundation for Animals

Voluntary registry: affected dogs are under-reported and evaluated dogs skew toward breeding stock, so true prevalence in the wider population is higher. OFA rank 1 = highest rate among the breeds listed. The Boxer's elbow figure is among the lowest in the OFA table; the American Boxer Club's recommended screen is the heart, not the elbow (see health tests).

Most common disorders

Wikipedia (editorial) lists cancers, aortic stenosis and arrhythmogenic right ventricular cardiomyopathy ('Boxer cardiomyopathy'), hypothyroidism, hip dysplasia, degenerative myelopathy, epilepsy, bloat, entropion, spondylosis deformans, Boxer colitis, corneal ulcers and juvenile kidney disease. It cites a UK Kennel Club health survey in which cancer accounted for 38.5% of Boxer deaths, old age 21.5%, cardiac causes 6.9% and gastrointestinal causes 6.9%, with a median lifespan of 10.25 years, and calls the breed particularly prone to mast cell tumours. AKC CHIC list (parent club): hips, elbows, thyroid, aortic/subaortic stenosis cardiac exam, ARVC DNA test, annual Holter monitor, degenerative myelopathy DNA test. RKC good practice: BVA/KC elbow, eye and hip schemes.

EditorialWikipedia

Editorial: Wikipedia summarising a UK Kennel Club survey that was not opened. No VetCompass Boxer paper was opened. Treat the percentages as a pointer to the survey, not a verified figure.

What the studies found

Population-level findings, shown as a spread. Breed sets the odds; the parents set the dog.

Aggression, as studied

C-BARQ online sample, 70 Boxers: 5.7% of owners reported a snap, bite or attempt to bite at a stranger, 0% at an owner, 15.7% at an unfamiliar dog and 5.3% in dog rivalry. The authors name the Boxer among the breeds that stood out for aggression toward unfamiliar dogs, and note that in a German study Boxers were more often the victims than the aggressors in inter-dog conflicts.

StudiedDuffy D.L., 2008

The Boxer was in the online sample only (n = 70, mean age 4.1 years), so no Table 5 breed mean is published and no C-BARQ subscale means are recorded. Population-level findings, never a prediction for one dog.

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. 11 sources on this page. Found something wrong? Tell us and the correction is logged with its date.
