Chihuahua Breed Characteristics

Understanding your Chihuahua's tiny size and big personality is essential for responsible breeding

Weight Range

Male: 3-6 lbs

Female: 3-6 lbs

Height at Shoulder

Male: 5-8 inches

Female: 5-8 inches

Life Expectancy

14-18 years

One of the longest-lived breeds

Temperament

Alert, Confident

Big dog in tiny body

Unique Chihuahua Traits

Two Coat Varieties

Smooth coat and long coat varieties. Both equal in the show ring. Long coats require more grooming but same health considerations.

Apple vs Deer Head

Apple heads have rounder skulls (breed standard). Deer heads have longer noses and may have fewer breathing issues. Both have devoted followings.

Napoleon Complex

Often fearless with larger dogs. Can be aggressive if not properly socialized. Need confident handling despite small size.

Temperature Sensitive

Cannot regulate body temperature well. Need sweaters in cold weather. Prone to shivering from cold or stress.

IMPORTANT HEALTH INFORMATION

Chihuahua Health Considerations

Despite their long lifespan, Chihuahuas face several health challenges related to their tiny size

Patellar Luxation

High Risk

OFA patella evaluation mandatory. Very common in Chihuahuas. Both parents should be certified normal. Can require expensive surgery.

Heart Disease (Mitral Valve Disease)

High Risk

Annual cardiac evaluation recommended. Common in older Chihuahuas. Start screening at 1 year. Can be managed with medication if caught early.

Hypoglycemia

High Risk

Especially dangerous in puppies under 4 months and tiny adults. Educate buyers on feeding schedules. Never breed extremely small dogs.

Hydrocephalus (Water on Brain)

Moderate Risk

More common in apple head Chihuahuas with open fontanels (moleras). Watch for dome-shaped heads, wide-set eyes. Can be fatal.

Dental Disease

High Risk

Tiny mouths lead to overcrowded teeth. Dental care essential. Many need teeth pulled young. Screen for proper bites.

Eye Problems

Moderate Risk

Annual CERF eye exams required. Prone to corneal ulcers due to prominent eyes. Also cataracts and glaucoma.

Collapsed Trachea

Moderate Risk

Common in toy breeds. Characterized by honking cough. Use harnesses, not collars. Can be hereditary.

Molera (Open Fontanel)

Low-Moderate Risk

Soft spot on head that never closes. Makes dogs vulnerable to head injury. Common but risky trait.

Critical: Size-Related Breeding Risks

NEVER breed females under 4 pounds. Tiny females face extreme pregnancy and whelping risks:

  • High risk of pregnancy toxemia
  • C-sections often required due to puppy size vs pelvis
  • Hypoglycemia during pregnancy and nursing
  • Higher puppy mortality rates
  • Mother may not survive difficult births

The "teacup" Chihuahua trend is unethical and dangerous. Breeding for extreme small size causes suffering and early death. Standard-sized Chihuahuas (4-6 lbs) are already tiny enough and face fewer health issues.

Chihuahua Breeding Guidelines

Follow these essential guidelines for responsible Chihuahua breeding

Optimal Breeding Age

Male Chihuahuas

1.5 to 8 years

Female Chihuahuas

2 to 6 years

Wait until fully grown. Females under 4 lbs should NEVER be bred due to high mortality risk.

Health Testing Requirements

  • Patella evaluation (OFA) - MANDATORY
  • Cardiac evaluation - MANDATORY annually
  • Eye Examination (CERF/OFA) - Annual requirement
  • Dental examination - Important due to breed issues
  • Basic health panel including blood sugar - Recommended
  • Hip X-rays (OFA) - Optional but helpful
  • Legg-Calve-Perthes screening - If limping history

Small size doesn't mean fewer health issues. Comprehensive testing is essential for ethical breeding.

Breeding Frequency

Females: Maximum once per year, 3 litters lifetime

Skip at least one heat cycle between litters

Tiny dogs have difficult pregnancies. C-sections common. Limit breeding to preserve health

Additional Breeding Considerations

  • Hypoglycemia Prevention: Educate all buyers about feeding schedules. Puppies need food every 2-3 hours. Send home with corn syrup for emergencies.
  • C-Section Planning: Have emergency vet on standby. Many Chihuahuas cannot deliver naturally. Budget $1,500-$3,000 per litter for potential C-section.
  • Socialization Critical: Chihuahuas can become fear-aggressive without proper socialization. Start handling at 3 weeks. Expose to various people and situations.
  • Home Safety: Educate buyers about Chihuahua-proofing homes. Can be injured by falls, stepped on, or attacked by larger pets. Not suitable for families with young children.
