Chihuahua information and Characteristics

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.

Meet the Chihuahua: the world’s smallest dog

The Chihuahua is famous for being the world's smallest breed yet having huge personality. Recognised by the UK Kennel Club, these toy breeds normally weigh 1.8–2.7 kg and stand 12–20 cm tall, making them classic lap dogs for city flats or country cottages alike. Two official coat types exist—smooth coat and long haired—while head shapes are described as apple head (common) or deer head (less common). A craze for “teacup Chihuahuas” has spread online, but experts agree they are not a separate breed; breeding ultra-tiny puppies can increase health risks such as low blood sugar and fragile growing bones.

Chihuahua History & Origin

Historians trace the Chihuahua to the Mexican state of the same name, where tiny companion dogs called Techichi lived with the Toltec people. Spanish traders later spread these companion animals across the globe. Today the breed ranks among the UK’s most popular small dogs: the Kennel Club registered 998 long-coat Chihuahuas in 2023 and 915 in the first three quarters of 2024. Short-coat numbers are similar, showing steady demand even as some other dog breeds decline.

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 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: big hearts, bold brains

Fans call them little dogs with big personalities. Well-socialised Chihuahuas are alert, loyal and fun. Without training, though, they can become yappy or wary of strangers and larger dogs. Early basic obedience training—sit, stay, recall—PLUS lots of positive exposure to other pets and young children keeps unwanted behaviours at bay. Because they bond closely with their family members, many Chihuahuas shake when left alone or in cold weather; acclimate them gradually to short separations and buy a fitted jumper for chilly walks. Puzzle toys and short bursts of scent games satisfy their smart, high-energy dog brains indoors.

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.

Training & mental stimulation

Despite their size, Chihuahuas thrive on structured obedience training. Start chihuahua puppy classes at 12 weeks so they meet other breeds early. Short, upbeat five-minute sessions suit short attention spans; finish before they tire. Teach “touch” to redirect barking and “leave it” to prevent ankle-chasing. Agility tunnels and puzzle toys work their quick brains. Because some individuals have an independent streak, mix scent-work or dodge games so they learn at their own pace. Remember: punishment damages trust; reward calm behaviour instead.

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 & legal duties in the UK

According to PDSA estimates, a Chihuahua costs at least £50 per month and up to £8,900 across their lifetime, excluding emergencies. Budget for:

• Quality food (~£15/month)

• Annual vaccinations and flea / worm cover (~£200/year)

• Insurance (from £20/month)

• Neutering (£150–£300)

• Dental scale & polish every 12–18 months (£250+ if tartar builds up)

By law, every dog in the UK must be microchipped and registered by eight weeks; failure carries a £500 fine. ID tags are still compulsory in public.

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.
