47 free Chihuahua trivia questions with answers — nature quiz, new questions added Aug 2026.
This Chihuahua trivia quiz covers the smallest recognised breed in the world from its Mexican roots to its pop-culture fame. Questions run through the ancient-DNA studies that found a trace of pre-Columbian dog in the breed, Cortés and the Aztecs, the extinct Techichi of the Toltecs, and the first AKC registration in 1904. Then the standard: apple domes versus deer heads, the molera soft spot, heights, FCI and AKC weights, the merle ban, and why 'teacup' breeding is a problem. Health questions take in hypoglycemia and the honey remedy, whelping difficulties and the life-expectancy studies. The pop-culture half covers Gidget the Taco Bell Chihuahua and the $30 million lawsuit, Beverly Hills Chihuahua, Ren Höek of Ren & Stimpy, Paris Hilton's Tinkerbell, Wheely Willy, and record holders Boo Boo, Milly and her 49 clones. Questions run from easy to expert with the difficulty shown on each one, and every answer was checked against a reference page and carries its citation.

Midget
Midget, owned by H. Raynor of Texas, became the first Chihuahua registered by the American Kennel Club in 1904.
Q 07Breed standards call for a Chihuahua skull of what shape?
Apple-shaped
Apple-shaped: the AKC and FCI standards describe a well-rounded 'apple dome' skull, and a flatter head is counted as a fault in the show ring.
Q 08What is the 'molera' that many Chihuahuas have on their heads?
A soft spot like a baby's fontanel
A molera is a soft spot like a baby's fontanel, where the skull bones have not fused; it is hard to see but easy to feel with a fingertip.
Q 09The older Chihuahua type with a flat-topped head, wider-set eyes and longer legs is known as what type?
Deer
The 'deer' type, with a flatter head and longer legs, may be registered but deviates from the apple-dome standard and is penalised as a fault in the show ring.
Q 10A Chihuahua's 'stop', where muzzle meets skull, is described as close to how many degrees?
90
Close to 90 degrees: the breed standard's apple-dome head has a sharply defined stop where muzzle meets skull, set off by large round eyes and big ears.
Q 11How tall does a typical Chihuahua stand?
6 to 9 inches
6 to 9 inches is the typical height; breed standards specify weight and proportions rather than height, and some pets reach 12 to 15 inches.
Q 12Which comedian voiced Papi, the lovestruck Chihuahua in Disney's Beverly Hills Chihuahua (2008)?
George Lopez
George Lopez voiced Papi, the landscaper's Chihuahua who falls for the pampered heroine, in the 2008 Disney film directed by Raja Gosnell.
Q 13Under the American Kennel Club standard, a show Chihuahua must not exceed what weight?
6 pounds

Q 21The Techichi, an ancestor of the Chihuahua, was bred by which Mesoamerican culture in the 9th century?
The Toltecs
The Toltecs bred the Techichi, and the Aztecs later bred it down into the smaller, lighter dog known today.

Its ears were sometimes cropped close to the head, but the tail was left natural.

Q 14In 2009 the British Chihuahua standard dropped a clause preferring which of two equally good dogs?
The more diminutive one
The more diminutive one: in 2009 the UK Kennel Club removed the clause 'if two dogs are equally good in type, the more diminutive one is preferred', part of its health-driven revision of breed standards.
Q 15Why do many breeders try to produce ever-smaller Chihuahuas?
'Teacup' dogs command higher prices
'Teacup' dogs command higher prices: the tiniest Chihuahuas are in higher demand, even though larger breeding females are less likely to suffer obstructed labour and the breed does not breed true for size.
Q 16Which coat pattern did the UK Kennel Club remove from the Chihuahua standard in 2007 for health reasons?
Merle
Merle: in 2007 the Kennel Club stopped registering merle puppies and amended its standard to disqualify the pattern, citing deafness and eye defects linked to the merle gene; the FCI also bars it.
Q 17According to the American Kennel Club, Chihuahuas are not recommended for which households?
Families with young children
Families with young children: the AKC advises against the breed for homes with small children, since like many small dogs Chihuahuas can show above-average aggression and their size makes rough handling risky.
Q 18What home remedy do vets recommend for mild hypoglycemia in toy-breed puppies?
Half a teaspoon of honey
Half a teaspoon of honey: a simple sugar such as honey or corn syrup rubbed on the gums raises blood glucose fast; small, lean or infrequently fed toy-breed puppies are most at risk.
Q 19A 2024 UK study found what life expectancy for the Chihuahua?
11.8 years
11.8 years: the 2024 UK study put the Chihuahua at 11.8 years, below the 12.7-year purebred average, while a 2022 UK study using veterinary data had given just 7.91 years.
Q 20A UK study found Chihuahua bitches suffer dystocia how many times more often than the average dog?
10.4-fold
10.4-fold: a UK study of emergency-care records found Chihuahua bitches 10.4 times as likely to suffer dystocia as the average dog; tiny mothers and relatively big-headed puppies make whelping difficult.
Q 24Mesoamerican peoples believed the Techichi could do what after its owner's death?
Guide the human soul in the afterlife
Guide the human soul in the afterlife: Techichis were often sacrificed and buried with their owners, in the belief that the dog would lead the soul through the underworld.
