Chihuahua

The smallest recognised breed. The apple-domed head is the standard type; a longer-muzzled 'deer head' form is common and not a separate breed.

What it looks like

Very small with a rounded apple-shaped skull, large erect ears, prominent round eyes, and a sickle tail carried up and over. Smooth or long coated.

The characters that confirm it

  • An apple-domed skull with a short muzzle and a distinct stop.
  • Very large erect ears, flaring to the sides at rest.
  • Under about 3 kg — anything much larger is a mix.
  • A sickle tail carried up and curving over the back.

Temperament

Bold, alert and frequently under-socialised, which produces much of the reputation. Genuinely fragile physically.

Health

Patellar luxation, tracheal collapse, hydrocephalus and dental crowding. A soft spot on the skull, the molera, persists into adulthood in many and requires care. Hypoglycaemia in puppies is a real emergency risk.

Confused with

Russian Toy

Longer legs, a finer frame and a more delicate head.

Small erect-eared mixed dogs get labelled Chihuahua routinely, and chihuahua mixes are among the commonest shelter dogs in the southwest.
