Black Long Haired Chihuahua

The black long haired Chihuahua is one of the most visually striking variations within the Chihuahua breed. While the American Kennel Club recognizes Chihuahuas in two coat varieties — smooth and long — the combination of a solid black coat with long, flowing fur is relatively uncommon, making these dogs particularly sought after by breed enthusiasts. Despite their dramatic appearance, black long haired Chihuahuas share the same breed standard, temperament profile, and health considerations as any other Chihuahua. The color and coat length are cosmetic traits, not indicators of a separate breed or fundamentally different personality.

If you're considering bringing one of these compact companions into your home, this guide covers everything from their origin and physical specs to the real costs of ownership and health conditions you need to watch for. We've compiled data from breed registries, veterinary references, and practical owner experience to give you a complete picture.

Breed Overview: Origin, Size Class & Lifespan

The Chihuahua traces its roots to the Mexican state of Chihuahua, where the breed was first documented in the mid-19th century. Archaeological and historical evidence suggests these dogs descend from the Techichi, a small companion dog kept by the Toltec civilization as early as the 9th century CE. The AKC officially recognized the breed in 1904, and both smooth-coat and long-coat varieties have been part of the standard since the breed's early registry years.

The long-haired variety likely developed through selective breeding and possibly crossbreeding with other small, long-coated breeds such as the Papillon and Pomeranian during the late 1800s. The black coat color is controlled by the dominant B allele at the B-locus, meaning a Chihuahua only needs one copy of the dominant black gene to express black pigmentation. However, solid black long haired specimens are less common because the long coat gene is recessive (requiring two copies) and many black Chihuahuas carry markings (tan points, white patches) rather than being solid.

Physical Characteristics of the Black Long Haired Chihuahua

The black long haired Chihuahua conforms to the same AKC breed standard as all Chihuahuas, with the distinguishing features being coat length and color. Here's what you can expect physically:

Body structure: Compact and well-balanced, with a slightly longer body than tall. The head is distinctly apple-domed (rounded skull) with a well-defined stop. Ears are large, erect, and flared, held at roughly a 45-degree angle when alert. The tail is moderately long, carried in a sickle shape or loop over the back, with a plume of longer fur in the long-coated variety.

Weight and height: Adult black long haired Chihuahuas typically weigh between 2–6 lb (0.9–2.7 kg), with most falling in the 3–5 lb (1.4–2.3 kg) range. Height at the withers measures 5–8 inches (12.7–20.3 cm). The AKC breed standard disqualifies any Chihuahua over 6 lb from conformation showing, though pet-quality dogs may occasionally exceed this slightly without health concern, provided their body condition score remains ideal (4–5 on a 9-point scale).

Coat details: The long coat is soft to the touch, either flat or slightly wavy. It is longer around the neck (forming a ruff or "lion's mane" effect), on the ears (feathering or "fringe"), on the backs of the legs, and on the tail. A black long haired Chihuahua's coat may appear to have subtle brown or rust highlights in direct sunlight — this is normal sun-bleaching and does not indicate a different color gene. Some individuals have a sparse undercoat; those with a denser undercoat will shed more seasonally.

Advantages of the Long Black Coat

  • Visually distinctive — stands out in any setting
  • Long coat provides slightly more cold-weather insulation than smooth coat
  • Less prone to visible skin irritation or sunburn than light-colored coats
  • Dirt and debris are less visible on black fur between baths

Coat Challenges to Anticipate

  • Longer fur around the rear can collect fecal matter — requires sanitary trims
  • Black fur shows prominently on light-colored furniture and clothing
  • Matting behind ears and in armpits if brushing is skipped
  • Coat takes longer to dry after bathing (20–40 minutes with a blow dryer on cool)

Temperament & Personality: What to Expect

Black long haired Chihuahuas carry the same bold, alert temperament as the breed at large. Coat color and length do not influence personality — but individual lineage, early socialization, and handler behavior play significant roles. Here are the core traits you'll encounter:

1. Fiercely devoted to their primary person. Chihuahuas are notorious for forming an intense bond with one household member. This isn't generic loyalty — it manifests as following you room-to-room, demanding lap time, and showing visible preference for you over others. In multi-person households, your Chihuahua will likely pick a "favorite" within the first few weeks.

2. Alert and vocal. These dogs are exceptional watchdogs for their size. They will bark at doorbell rings, unfamiliar footsteps, other dogs passing the window, and sometimes at nothing you can perceive. Expect a Chihuahua to vocalize with a combination of barks, growls, and a distinctive "roo-roo" sound. This is breed-typical and trainable to a degree, but not eliminable.

3. Confident to the point of boldness. Chihuahuas routinely challenge dogs ten times their size. A black long haired Chihuahua at a dog park may strut up to a Golden Retriever with zero hesitation. This confidence is charming but requires management — they can provoke larger dogs and get injured as a result.

4. Sensitive to household emotional tone. These dogs read their owners closely. Arguments, stress, and changes in routine can trigger clinginess, trembling, or appetite changes. They thrive in calm, predictable environments.

5. Playful in bursts, not marathons. Expect 10–15 minute play sessions (chasing a flirt pole, tugging a small rope toy) followed by a long nap. Chihuahuas are sprinters, not endurance athletes.

Exercise & Activity Requirements

A black long haired Chihuahua needs 30–45 minutes of total daily activity, which can be broken into two or three sessions. Here's a practical breakdown:

Recommended Daily Activity Plan
ActivityDurationFrequencyNotes
Leash walk (short)10–15 minutes2x/dayUse a harness, never a neck collar — trachea is fragile
Indoor play session10–15 minutes1–2x/dayFlirt pole, puzzle toys, small fetch
Mental enrichment5–10 minutes1x/daySnuffle mats, lick mats, hide-and-seek with treats
Socialization outing15–20 minutes2–3x/weekCafé patios, pet-friendly stores, calm dog parks

Important exercise caveats: Chihuahuas are susceptible to hypoglycemia, especially puppies under 6 months. Always carry a small tube of Nutri-Cal or honey water on longer outings. In cold weather (below 45°F / 7°C), a fitted dog sweater is recommended even for long-coated varieties — their small body mass loses heat rapidly. In hot weather (above 80°F / 27°C), limit walks to early morning and evening; black-coated dogs absorb more solar radiation than lighter colors.

Health Issues: What Black Long Haired Chihuahuas Are Prone To

Chihuahuas are generally one of the longest-lived toy breeds, but they carry specific health risks. Coat color does not affect health predisposition — these conditions apply across all Chihuahua varieties. Always consult your veterinarian for breed-appropriate screening.

Breed-Specific Health Conditions
ConditionDescriptionEstimated PrevalenceScreening / Prevention
Patellar LuxationKneecap slips out of position, causing intermittent lameness or "skipping" gait~8–15% of Chihuahuas (OFA data)Annual orthopedic exam; avoid jumping from high furniture; surgical correction if Grade III–IV
Tracheal CollapseWeakening of tracheal cartilage rings, causing honking cough and exercise intoleranceEstimated 10–20% in toy breeds; Chihuahuas among highest riskUse harness only; maintain lean weight; medical management with cough suppressants; stent surgery in severe cases
Dental Disease (Periodontitis)Plaque and tartar buildup leading to tooth loss, oral infection, and potential heart/kidney complications~80% of Chihuahuas show signs by age 3Daily tooth brushing with enzymatic toothpaste; professional dental cleaning under anesthesia every 1–2 years
Mitral Valve Disease (MVD)Progressive degeneration of the mitral valve leading to congestive heart failure~10–15% of Chihuahuas over age 8Annual cardiac auscultation from age 5; echocardiogram if murmur detected; medications (pimobendan, enalapril) per veterinary cardiologist
HypoglycemiaDangerously low blood sugar, particularly in puppies and very small adults under 3 lbCommon in puppies under 4 months; occasional in tiny adultsFrequent small meals (3–4x/day for puppies); keep Nutri-Cal on hand; monitor for lethargy, trembling, collapse
HydrocephalusExcess cerebrospinal fluid in the skull; associated with the breed's domed skull shape~2–5% in Chihuahuas; higher in dogs with extremely large "apple" headsNeurological exam if puppy shows dome-shaped head, downward gaze, seizures, or developmental delays

Molera (open fontanel): Many Chihuahua puppies are born with a soft spot on the top of the skull, similar to a human baby's fontanel. In most dogs this closes by 6–12 months. An open molera in adulthood is not automatically dangerous but requires protection from head trauma. Discuss with your vet during puppy wellness visits.

When to Call the Vet Immediately:
  • Honking or gagging cough that doesn't resolve within 24 hours
  • Sudden collapse, pale gums, or inability to stand
  • Seizures or episodes of disorientation
  • Refusal to eat for more than 12 hours (puppies) or 24 hours (adults)
  • Swollen abdomen or repeated unproductive vomiting (possible GDV, rare but possible)

ASPCA Animal Poison Control: (888) 426-4435 (24/7, consultation fee applies) if your dog ingests anything toxic.

Grooming Requirements for the Long Black Coat

The long coat of a black Chihuahua requires more maintenance than the smooth variety, but it's manageable with a consistent routine. Here's what you'll need:

Tools: A stainless steel pin brush (medium size, rounded tips), a fine-toothed metal comb for detangling, a slicker brush for the undercoat (if present), blunt-tipped grooming scissors for sanitary trims, and a dog-specific blow dryer or a human dryer on cool/low setting.

Brushing schedule: Brush 2–3 times per week, spending 10–15 minutes per session. Focus on high-matting areas: behind the ears, under the front legs (armpits), the ruff around the neck, and the "pants" area on the rear legs. Use the comb after brushing to check for tangles the brush missed.

Bathing: Every 3–4 weeks using a gentle, dog-formulated shampoo. Black coats benefit from shampoos designed for dark coats (brands like BioSilk or Earthbath make color-enhancing formulas) that prevent reddish fading. Conditioner is recommended for long coats to reduce static and tangling. Rinse thoroughly — residual shampoo causes skin irritation. Drying time with a blow dryer on cool: approximately 20–40 minutes depending on coat density.

Sanitary trim: Every 4–6 weeks, trim the fur around the anus and vulva/prepuce to 1/4 inch using blunt-tipped scissors. This prevents fecal matting and urinary tract contamination.

Nail trims: Every 2–3 weeks. Chihuahua nails grow quickly relative to their paw size, and overgrown nails alter gait and contribute to patellar stress. Use a small guillotine-style clipper or a Dremel pet nail grinder (model 7300-PT) on the lowest speed.

Ear care: Check weekly for debris and wax. Clean with a veterinary ear wash (e.g., Epi-Otic Advanced) on a cotton round — never use cotton swabs inside the ear canal. Long-haired Chihuahuas have better ear airflow than floppy-eared breeds, but the ear fringe can trap moisture after baths.

Training, Intelligence & Socialization

Chihuahuas rank moderately in working/obedience intelligence — they understand commands but are not always motivated to comply on demand. Think of them as intelligent independents rather than biddable workers. This is not stubbornness in the traditional sense; it's a breed that was developed as a companion, not a working dog, and they evaluate whether a command is "worth it" before responding.

Trainability rating: 3 out of 5 for obedience reliability. They excel at learning tricks and household routines but may be inconsistent with recall in high-distraction environments.

Recommended methods: Positive reinforcement exclusively. Use high-value treats (small pieces of boiled chicken, freeze-dried liver, Zuke's Mini Naturals) and keep training sessions to 5–8 minutes maximum. Force-free, LIMA (Least Intrusive, Minimally Aversive) methods produce the best results. Never use shock collars, prong collars, or physical corrections — Chihuahuas are physically fragile and emotionally sensitive; aversive methods damage trust and can trigger fear-based aggression.

Priority training goals:

  1. Housetraining: Chihuahuas are notoriously difficult to housetrain. Their small bladders require outdoor trips every 2–3 hours for puppies and every 4–5 hours for adults. Crate training with a properly sized crate (just large enough to stand, turn, and lie down) accelerates the process. Expect 4–8 months for reliable housetraining — some individuals take longer. Indoor pee-pad stations are a practical supplement for apartment living.
  2. Socialization: Critical window is 8–16 weeks. Expose your puppy to diverse people, surfaces, sounds, and other vaccinated dogs. Under-socialized Chihuahuas are at high risk for fear-based reactivity and defensive biting.
  3. Handling desensitization: Touch their paws, ears, mouth, and tail daily from puppyhood. This makes grooming, nail trims, and veterinary exams far less stressful.
  4. Bark management: Teach a "quiet" cue using counter-conditioning — reward silence after a bark alert rather than yelling (which the dog interprets as you barking along).

Family Suitability: Kids, Other Pets & Living Spaces

With children: Black long haired Chihuahuas are best suited to households with children aged 8 and older who have been taught gentle handling. A Chihuahua's small frame is easily injured by rough play, drops, or squeezing. A child falling on or stepping on a 4-lb dog can cause rib fractures, spinal injury, or internal bleeding. Supervised, calm interaction is fine; unsupervised play with young children is not recommended.

With other dogs: Chihuahuas generally coexist well with other dogs in the household, especially if introduced as puppies. They often prefer the company of other Chihuahuas or similarly sized toy breeds. Introducing a Chihuahua to a large, high-prey-drive dog (e.g., a terrier or hound) requires careful management — the size disparity creates genuine risk. Always supervise initial interactions and separate dogs when unsupervised until trust is established over weeks to months.

With cats: Many Chihuahuas live harmoniously with cats, particularly when raised together. The cat is often the more dominant party in the relationship. Introduce gradually using scent swapping and visual barriers before face-to-face meetings.

Apartment living: Excellent apartment dogs in terms of space requirements — a 600 sq ft apartment is perfectly adequate if daily walks and indoor play are maintained. The main challenge is barking; thin-walled apartments may generate noise complaints. Training a "quiet" cue and providing white noise or calming background audio when you're away can mitigate this.

Cost of Ownership: Purchase Price & Annual Expenses

Black long haired Chihuahuas command a price premium over more common color/coat combinations due to relative rarity. Here's a realistic cost breakdown based on 2026 market data:

Puppy purchase price:

  • From a responsible AKC-registered breeder with health testing: $1,500–$3,500
  • Premium/show-quality lines with champion parents: $3,500–$6,000+
  • Adoption/rescue (Chihuahua-specific rescues like Chihuahua Rescue & Transport): $200–$500

First-year total cost estimate:

Expense CategoryEstimated Cost (USD)
Puppy purchase$1,500–$3,500
Initial veterinary visits (3 puppy wellness + vaccines)$400–$700
Spay/neuter$300–$600
Supplies (crate, harness, bed, bowls, grooming tools)$200–$400
High-quality food (annual)$250–$450
Pet insurance (annual premium)$300–$600
Grooming supplies and professional trims$100–$250
Training classes (puppy socialization + basic)$150–$350
First-year total$3,200–$6,850

Ongoing annual cost (years 2+): $1,200–$2,800/year depending on health status, insurance coverage, and grooming frequency. Budget an additional $500–$2,000 annually after age 8 for senior care (dental cleanings, cardiac monitoring, joint supplements).

A note on breeders: Responsible breeders health-test their breeding stock for patellar luxation (OFA evaluation), cardiac conditions (OFA cardiologist clearance), and eye disorders (CERF/OFA ophthalmologist exam). They provide a written health guarantee, require a spay/neuter contract for pet-quality puppies, and have a take-back clause committing to reclaim the dog at any point in its life if you cannot keep it. Avoid breeders who advertise "rare black long hair" at inflated prices without providing health test documentation. Adoption from a Chihuahua-specific rescue is an equally valid and often more affordable path.

Frequently Asked Questions

Is the black long haired Chihuahua right for first-time owners?

Yes, with some caveats. Chihuahuas are manageable in size, relatively low in exercise needs, and don't require a yard. However, their housetraining difficulty, tendency to bark, and physical fragility mean first-time owners should be prepared to invest in training classes, read breed-specific resources, and commit to careful handling. If you want a low-maintenance, easy-to-train first dog, a Chihuahua may be more challenging than expected. If you're patient and willing to learn, they can be a wonderful first breed.

How much exercise does a black long haired Chihuahua need daily?

30–45 minutes total per day, split into two short leash walks (10–15 minutes each) and one or two indoor play sessions. Mental enrichment (puzzle toys, snuffle mats, training games) should supplement physical activity. They are not a breed that needs running or hiking — their small size means even a short walk provides significant cardiovascular effort.

What health problems is this breed prone to?

The most significant breed-specific conditions are patellar luxation (knee), tracheal collapse (airway), severe dental disease (affecting ~80% by age 3), mitral valve disease (heart, primarily in seniors), hypoglycemia (especially in puppies), and hydrocephalus. Regular veterinary checkups — at minimum annually for adults and twice yearly for seniors — are essential for early detection. Ask your vet about breed-appropriate screening protocols at each life stage.

How big does a black long haired Chihuahua get?

Adults typically weigh 3–5 lb (1.4–2.3 kg), though the breed standard allows up to 6 lb (2.7 kg). Height at the shoulder ranges from 5–8 inches (12.7–20.3 cm). Males and females are similar in size, with males occasionally being slightly heavier. "Teacup" Chihuahuas weighing under 2 lb are not a recognized variety — they are typically runts or dogs bred to be dangerously small and carry elevated health risks.

Is a black long haired Chihuahua good with children?

They do best with children aged 8+ who understand gentle handling. Their small, fragile bodies are at genuine risk of injury from toddlers and young children who may accidentally drop, squeeze, or fall on them. If you have young children, consider waiting until they're older or choosing a sturdier small breed like a Cavalier King Charles Spaniel or a Boston Terrier.

How much does a black long haired Chihuahua cost to buy and maintain?

Expect to pay $1,500–$3,500 for a puppy from a responsible breeder, or $200–$500 through a breed-specific rescue. First-year total costs (including the puppy, vet care, supplies, and food) typically run $3,200–$6,850. Ongoing annual costs settle to $1,200–$2,800 per year for food, insurance, grooming, and routine veterinary care. Senior care costs increase significantly after age 8.

Does the black coat require special care compared to other Chihuahua colors?

Not medically, but cosmetically yes. Black fur shows dander and dust more readily, so regular brushing keeps the coat looking clean between baths. Sun exposure can cause the black coat to develop reddish-brown highlights (sun bleaching), which is harmless but may be undesirable if you plan to show. A leave-in coat spray with UV protection can help. Otherwise, grooming needs are identical to long haired Chihuahuas of any color.

The black long haired Chihuahua is a striking, personality-rich companion dog that rewards patient owners with deep loyalty and years of entertainment. Their compact size makes them adaptable to nearly any living situation, and their long lifespan means you're signing up for a relationship that could last 15 years or more. If you're prepared for the housetraining patience, the barking management, and the careful handling their tiny frame requires, a black long haired Chihuahua can be one of the most rewarding dogs you'll ever own.
