TRANSLATION : C. Seidler. Revised by R.Triquet (amendments
to the standard).
ORIGIN : Mexico.
DATE OF PUBLICATION OF THE ORIGINAL VALID STANDARD
UTILIZATION : Companion dog.
CLASSIFICATION F.C.I. : Group
9 Companion and Toy Dogs.
Section 6 Chihuahueño.
Without working trial.
BRIEF HISTORICAL SUMMARY :
The Chihuahua is regarded as the smallest pedigree
dog in the world and carries the name of the largest
state of the Mexican Republic (Chihuahua). One assumes
that these dogs used to live in the wild and, at
the time of the Toltec civilization, were captured
and domesticated by the natives. Representations
of a Toy dog called « Techichi » which
lived in Tula, were used as decorations on town
architecture. These statues are very similar to
the present day Chihuahua.
GENERAL APPEARANCE : This dog
has a compact body. Of great importance is the fact
that his skull is apple-shaped and that he carries
his moderately long tail very high, either curved
or forming the shape of a semicircle with the tip
pointing towards the loin region.
IMPORTANT PROPORTIONS : Length
of body slightly greater than height at withers.
Desired, however, is an almost square body, especially
in males. In bitches, because of the function of
reproduction, a slightly longer body is permitted.
BEHAVIOUR / TEMPERAMENT : Quick,
alert, lively and very courageous.
CRANIAL REGION :
Skull : Well rounded apple head ( a characteristic
of the breed) preferably without a fontanel although
a small one is allowed.
Stop : Well marked, deep and broad as the forehead
is bulging over the set-on of muzzle.
FACIAL REGION :
Nose : Any colour permitted. Moderately short, pointing
Muzzle : Short, straight seen from side, broad at
set-on, tapering towards the tip.
Lips : Lean and close fitting.
Cheeks : Only slightly developed, very clean.
Jaws/Teeth : Scissor or pincer bite. Overshot, undershot,
as well as any other anomaly in position of upper
or lower jaw must be strictly penalized.
Eyes : Large, roundish in shape, very expressive,
not protruding, perfectly dark. Light eyes permissible,
but not desired.
Ears : Large, upright, widely open, broad at set-on,
gradually tapering towards their slightly rounded
point. In repose inclined laterally forming an angle
NECK : Upper profile slightly
Length : Medium length.
Shape : Thicker in dogs than in bitches.
Skin : Without dewlap. In the long-haired variety,
the presence of a neck-ruff with longer hair is
BODY : Compact and well built.
Topline : Level.
Withers : Only slightly marked.
Back : Short and firm.
Loin : Strongly muscled.
Croup : Broad and strong; almost flat or slightly
Chest : Ribcage broad and deep, ribs well sprung.
Seen from front, roomy but not exaggerated. Seen
from side, reaching to elbows. Not barrel shaped.
Lower Line : Formed by a clearly tucked up belly.
Slack belly is permitted but not desired.
TAIL : Set on high, flat in
appearance, of moderate length; broad at root, tapering
gradually towards the tip. Tail carriage is an important
characteristic of the breed : when the dog is moving
it is carried either high in a curve or in a semicircle
with tip towards the loin region, which gives balance
to the body, it should never be carried between
the hindlegs nor curled below the backline. The
hair on the tail depends on the variety and is in
harmony with the body coat. In the long haired variety,
the tail coat forms a plume. Tail is pendant in
repose and forms a slight hook.
FOREQUARTERS : Forelegs straight
and of good length; seen from the front, they form
a straight line with the elbows. Seen from the side,
they are upright.
Shoulders : Clean and moderately muscled. Good angulation
between shoulder-blade and upper arm.
Elbows : Firm and fitting close to body which ensures
Pasterns : Slightly sloping, strong and flexible.
HINDQUARTERS : Hindlegs well
muscled with long bones, vertical and parallel to
each other with good angulation at hip, knee and
hock joints, in harmony with angulation of forequarters.
Hocks : Short with well developed Achilles’
tendons; seen from rear, they are well apart straight
FEET : Very small and oval
with toes well apart but not splayed (neither hare-
nor cat-foot). Nails particularly well arched and
moderately long. Pads well developed and very elastic.
Dewclaws must be removed except in countries where
this practice is forbidden by law.
GAIT / MOVEMENT : Steps are long, springy, energetic
and active with good reach and drive. Seen from
rear, hind legs should move almost parallel to each
other, so that the foot prints of the hind feet
fit directly into those of the front feet. With
increasing speed, the limbs show a tendency to converge
towards the centre point of gravity (single track).
Movement remains free and springy without visible
effort, head raised and back firm.
SKIN : Smooth and elastic all
HAIR : In this breed there
are two varieties of coat.
• Smooth-haired : Coat is short, lying close
all over body. If there is an undercoat, the hair
is somewhat longer; sparse coat on throat and belly
permissible; slightly longer on neck and tail, short
on face and ears. Coat is glossy and its texture
is soft. Hairless dogs are not tolerated.
• Longed-haired : Coat should be fine and
silky, smooth or slightly wavy. Not too thick undercoat
desired. Coat is longer, forming feathering on ears,
neck, rear of front and hind legs, on feet and on
tail. Dogs with long billowing coat will not be

possible shades and combinations are admitted.
