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.
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.
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.

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.

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

point of gravity (single track). Movement
remains free and springy without visible
effort, head raised and back firm.
