Unique Sheltie Traits

Herding Heritage

Bred to herd sheep on Scotland's Shetland Islands. Strong herding instinct may manifest as nipping at heels or circling children/pets.

Double Coat Maintenance

Luxurious double coat requires extensive grooming. Sheds heavily twice yearly. Breeding pairs should have excellent coat quality.

Extreme Sensitivity

One of the most sensitive breeds. Can be overwhelmed by harsh training or chaotic environments. Temperament is crucial in breeding decisions.

Vocal Nature

Known for being "barky" - will alert to everything. While breed characteristic, excessive barking should be considered in breeding.

CRITICAL HEALTH INFORMATION

Shetland Sheepdog Health Considerations

MDR1 and CEA testing are absolutely mandatory for this breed - these tests can save lives

MDR1 Gene Mutation

High Risk

MANDATORY genetic testing. This mutation causes severe drug sensitivities that can be FATAL. ~15% affected, ~50% carriers in breed.

Collie Eye Anomaly (CEA)

High Risk

MANDATORY genetic testing. Present in ~50% of breed. Eye exam at 6-8 weeks critical for detection.

Progressive Retinal Atrophy (PRA)

Moderate Risk

Genetic testing available. Causes progressive blindness. Annual eye exams by veterinary ophthalmologist required.

Hip Dysplasia

Low-Moderate Risk

OFA or PennHIP evaluation recommended. Less common in this size breed but still important to screen.

Dermatomyositis

Moderate Risk

No genetic test available. Inflammatory condition affecting skin and muscles. Avoid breeding affected dogs.

Von Willebrand's Disease

Low-Moderate Risk

Genetic testing available. Bleeding disorder that can affect surgery outcomes.

Epilepsy

Low-Moderate Risk

No genetic test. Idiopathic seizures. Do not breed dogs with seizure history.

Gallbladder Mucocele

Low-Moderate Risk

Monitor with regular veterinary check-ups. Can be life-threatening if not caught early.

MDR1 Gene Mutation - Life-Threatening Risk

The MDR1 mutation causes severe sensitivity to common medications that can be FATAL. This includes many heartworm preventatives, anti-diarrheal medications, and certain anesthetics.

NEVER breed without MDR1 testing. Even carrier-to-carrier matings can produce affected puppies. All puppies must be tested before going to new homes to ensure proper medical care.

Shetland Sheepdog Breeding Guidelines

Follow these essential guidelines for responsible Sheltie breeding

Optimal Breeding Age

Male Shelties

2 to 8 years

Female Shelties

2 to 6 years

Wait until at least 2 years for full maturity and complete health testing. Females should have no more than 3-4 litters lifetime.

Health Testing Requirements

  • MDR1 Gene Test - MANDATORY (life-saving)
  • CEA (Collie Eye Anomaly) - MANDATORY genetic test
  • Eye Examination (CERF/OFA) - Annual requirement
  • PRA Genetic Test - Strongly recommended
  • Hip X-rays (OFA or PennHIP) - Recommended
  • Von Willebrand's Disease - Recommended
  • Thyroid Panel - Recommended annually

MDR1 and CEA testing are absolutely critical for this breed. Never breed without these tests.

Breeding Frequency

Females: No more than once per year, maximum 3-4 litters lifetime

Skip at least one heat cycle between litters

Shelties typically have 4-6 puppies per litter. Their sensitive nature requires careful monitoring during pregnancy and whelping.

Additional Breeding Considerations

  • Temperament Priority: Shelties are extremely sensitive. Only breed dogs with stable, confident temperaments. Excessive shyness or nervousness is often genetic.
  • Color Genetics: Blue merle to blue merle breeding can produce deaf/blind puppies. Always breed merle to tri-color or sable for safety.
  • Early Socialization: Critical for preventing shyness. Plan breeding timing to maximize socialization opportunities during key developmental periods.
  • Grooming Requirements: Ensure puppy buyers understand the extensive grooming needs. This is a major reason for Shelties being rehomed.
