Chihuahuas are the smallest common breed and most "small" dog clothing is still too big. Narrow chest, fine neck, short legs and very little body mass. Everything here starts at genuinely extra-small.

Fitting a Chihuahua

Measure chest girth and back length, and expect to need XS or XXS. Weight is a poor guide at this size because a 4lb and a 7lb chihuahua can be a size apart. Leg openings matter: too narrow and the dog will refuse to walk. Compare both measurements against the size chart on the individual product page, and size up if the dog falls between two.

They genuinely feel cold

Chihuahuas shiver more than any other breed for real reasons: minimal body fat, a thin coat and a very high surface-area-to-mass ratio. Indoor sweaters are not decorative for this breed in a cool house. Smooth-coat chihuahuas feel it more than long-coats.

Frequently asked questions

What size clothes fit a chihuahua?

Usually XS or XXS. Measure chest girth and back length rather than going by weight.

Why does my chihuahua shiver indoors?

Low body mass and a thin coat mean they lose heat fast. Shivering in a cool room is common and a light sweater usually settles it.

Do chihuahuas need clothes in summer?

Only for sun protection on very short-coated dogs. Otherwise skip layers in heat.
