Chihuahuas, often called the world’s smallest dogs, pack huge personalities into tiny bodies. Whether you’re considering a chihuahua puppy or simply curious about this iconic toy breed, this guide covers everything UK pet parents need to know about Chihuahua information and characteristics, from physical traits and temperament to health, training, costs, and more.
Breed Snapshot: At a Glance
Chihuahuas, known as one of the world's smallest dogs, are purebred dogs recognised by breed clubs such as the British Chihuahua Club Club. These tiny companions originate from the Mexican state of Chihuahua and come with huge personalities. Chihuahuas are popular lap dogs, known for being both energetic dogs and affectionate companions.
Chihuahua History & Origin
Chihuahuas trace their roots back to Mexico, specifically from the Mexican state of Chihuahua. They are believed to be descendants of the ancient Techichi dogs, revered by the Aztecs. Over time, they spread globally, becoming beloved pets due to their distinct physical attributes, such as erect ears, apple heads, or the alternative deer head shape.
Physical Characteristics
Size & Body Shape
Chihuahuas come in two head shapes: the classic apple head, with a rounded skull and erect ears, and the deer head, featuring a longer muzzle and a slightly leaner frame. Despite being the smallest breed, individual dog sizes vary—some chihuahua chihuahuas may remain under 2 kg, while others reach the upper end of the breed standard.
Coat Types & Colours
There are two coat types in Chihuahuas:
-
Smooth coat (short haired Chihuahuas): Requires minimal grooming, quick weekly brushes to remove loose hair.
-
Long haired Chihuahuas: Also called long haired, or long coated, they need brushing 2–3 times a week to prevent tangles.
Common coat colours include fawn, black-and-tan, chocolate, and cream. While merle appears in some lines, many breed clubs discourage it due to associated health risks.
Cold Weather Care
With such delicate physical attributes and minimal body fat, Chihuahuas struggle in cold weather. Pet parents often invest in dog jumpers or waterproof coats. For top-quality gear, explore FunnyFuzzy’s range of Chihuahua jumpers and jackets.
Temperament & Personality
Despite their status among lap dogs, Chihuahuas are energetic dogs with big personalities. They form strong bonds with their family members and can be protective, sometimes barking more than other breeds. Early socialisation with other dogs and other pets helps curb over-protective behaviour and teaches them to be confident around larger dogs.
Daily Care Requirements
Exercise Needs
Chihuahuas may be small, but they benefit from 20–30 minutes of daily walks and indoor play. Puzzle toys stimulate their sharp minds, while short walks keep them fit without overexertion—crucial for young age or older dogs.
Grooming Routine
Smooth coat Chihuahuas require brushing once a week, while long haired Chihuahuas need grooming several times weekly to manage loose hair. Regardless of coat type, regular nail trims, ear checks (erect ears are prone to wax buildup), and dental care prevent health conditions like dental disease.
Feeding & Nutrition
Opt for high-quality kibble formulated for toy breeds or small dogs. Measure portions based on your dog’s weight and dog’s age—chihuahua puppies need more frequent feeding, while adult dogs do well on 2 meals per day. Avoid free-feeding to prevent obesity, a common health concern.
Training & Socialisation
Chihuahuas are intelligent and generally easy to train with positive reinforcement. Basic obedience training and chihuahua training early on ensures they understand commands and helps manage their tendency to shake when anxious or cold. Address separation anxiety by gradually acclimatising them to being left alone.
Health & Diet
Due to their small size, Chihuahuas are prone to certain health issues such as dental disease, low blood sugar, Patellar luxation (kneecap dislocation)，Tracheal collapse，heart disease, ear infections, and joint problems. Regular vet visits and health tests are crucial. Providing high-quality dog food tailored to small breeds ensures proper nutrition and helps maintain a healthy dog's weight.
Living Environment
These little dogs thrive in homes with consistent attention and care. Due to their size and health risks, such as sensitivity to cold weather, a warm, comfortable home environment is essential.
Mental & Physical Stimulation
Engage your Chihuahua with toys, mental challenges, and short, regular exercise sessions to ensure they stay mentally sharp and physically fit.
Chihuahuas have big personalities packed into tiny bodies. Offering them love, patience, and proper care will make these feisty and loyal dogs your affectionate best friends, providing many years of companionship.
Are Chihuahuas Hypoallergenic?
Despite their small size and minimal grooming requirements, Chihuahuas are not hypoallergenic. They shed loose hair moderately, affecting pet parents with allergies. Regular grooming, such as weekly brushing for short-haired varieties and more frequent care for long-haired Chihuahuas, helps manage shedding and reduces allergy triggers.
Costs of Owning a Chihuahua in Britain
Owning a purebred Chihuahua from a reputable breeder can cost £800–£1,500. Rescue routes through the British Chihuahua Breed Club often offer lower fees. Monthly expenses—including food, insurance, and routine vet visits—average around £50, with lifetime costs nearing £8,900 excluding initial purchase (PDSA).
Legal & Practical Ownership Tips
In the UK, all dogs must be microchipped and wear a collar tag. When travelling, use airline-approved carriers and crash-tested car seats. Familiarise yourself with the Animal Welfare Act and review third-party liability requirements under local regulations.

Is a Chihuahua a good family dog?
Yes, Chihuahuas make loyal family members but are best with gentle older children due to their tiny frame and energetic temperament.

Whether you choose a smooth coat or long haired Chihuahuas, apple head or deer head, every individual dog shines when given the right care: regular exercise, puzzle toys for mental stimulation, basic obedience training, and annual health tests to monitor dental disease and other health risks. Recognised by the American Kennel Club and the Kennel Club UK for meeting breed standards, purebred Chihuahuas continue a long heritage that began in the Mexican state of Chihuahua.
As lap dogs and companion animals, Chihuahuas thrive in family life and adapt well to both bustling city flats and quieter country homes. To keep your Chihuahua cosy in cold weather, support their physical attributes with jumpers and waterproof coats, and remember—minimal grooming doesn’t mean no grooming.
