The Chihuahua (Long Coat) is a small companion dog with a bold personality that far outweighs its size. Originating from Mexico, this breed is one of the smallest pedigree dogs in the world, yet is known for being confident, alert, and deeply devoted to its owner.
Long-coat Chihuahuas share the same temperament as the smooth-coat variety, with the addition of a soft, flowing coat. They are popular as companion dogs but require careful handling, early socialisation, and owners who understand small-breed behaviour rather than treating them as accessories.
The Chihuahua (Long Coat) is a very small, lightly built dog with a graceful outline and expressive features. Despite their size, they are not delicate when bred correctly.
Key physical characteristics include:
A compact, well-balanced body
A long, soft coat that may be flat or slightly wavy
Large, round eyes with an alert expression
Large, upright ears
A moderately long tail, often carried over the back
Chihuahuas may have either an apple-shaped head (breed standard) or a deer-type head.

Chihuahua (Long Coat) dogs have an average lifespan of 14-17 years, making them one of the longer-lived pedigree breeds. However, their small size does come with specific health considerations.
Patellar luxation - Common in small breeds
Dental disease - Requires regular care
Heart disease - Particularly mitral valve disease
Hypoglycaemia -Especially in puppies
Tracheal collapse - Possible
Responsible breeders focus on health, structure, and temperament.
Long-coat Chihuahuas have modest exercise needs but still benefit from daily activity.
Ideal activities include:
Short daily walks
Indoor play
Training games
Daily exercise requirement: 30–60 minutes
Due to their size, Chihuahuas need nutrient-dense food in small portions.
Adults: 40-70 g per day
Puppies: Small, frequent meals to prevent low blood sugar
Weight should be monitored carefully.
The long coat requires regular but manageable grooming:
Brushing 2-3 times per week
Occasional trimming
Regular dental care
Chihuahuas form strong attachments and can develop separation anxiety if left alone too often. Calm, consistent routines help them feel secure.
The Chihuahua originates from Mexico and is named after the Mexican state of Chihuahua. The breed has ancient roots and was later refined into both smooth and long-coat varieties.
The long-coat variety is believed to have been developed through selective breeding rather than being a separate origin.
