Unique Yorkshire Terrier Traits

Victorian Ratting Heritage

Originally bred in Yorkshire, England to catch rats in textile mills. Despite tiny size, they have true terrier courage and tenacity.

Silky Steel Blue & Tan Coat

Born black and tan, coat lightens to steel blue and golden tan. Silky texture grows continuously like human hair. Requires daily grooming.

Big Dog in Tiny Body

Fearless personality despite 4-7 lb size. Will challenge dogs 50 times their weight. Often don't realize how small they are.

Extreme Fragility

Bones break easily from short falls. Can be injured by children or larger pets. Require careful handling and supervision at all times.

HIGH-RISK TOY BREED

Yorkshire Terrier Health Considerations

Yorkies face numerous health challenges due to their tiny size requiring careful breeding and buyer education

Luxating Patella

High Risk

Kneecap dislocation extremely common. OFA patella evaluation MANDATORY. Grades 3-4 require expensive surgery and cause lameness.

Tracheal Collapse

High Risk

Trachea cartilage weakness causes 'honking' cough and breathing difficulty. Avoid collars, use harnesses. Surgery needed in severe cases.

Hypoglycemia

High Risk

Low blood sugar common in tiny dogs. Can cause seizures, coma, death. Feed frequent small meals. Puppy buyers must understand signs.

Dental Disease

High Risk

Tiny mouths with crowded teeth. Need professional cleanings every 6 months. Many lose teeth by age 5. Daily brushing essential.

Liver Shunt

Moderate Risk

Portosystemic shunt more common in toy breeds. Bile acid test recommended. Can be fatal without expensive surgery.

Legg-Calve-Perthes Disease

Moderate Risk

Hip joint deterioration in toy breeds. Causes lameness and pain. Usually requires surgery. X-rays recommended before breeding.

Progressive Retinal Atrophy (PRA)

Low-Moderate Risk

Genetic test available. Causes blindness. Test breeding stock though uncommon in breed.

Cryptorchidism

Moderate Risk

Undescended testicles more common in toy breeds. Can cause cancer. Affected males should not be bred.

CRITICAL: Extreme Size Dangers

Yorkshire Terriers are among the most fragile dogs. At 4-7 pounds, they face constant life-threatening dangers that larger dogs never encounter. Many Yorkie deaths are preventable accidents.

Common fatal accidents:

  • Jumping off furniture - can break necks or suffer fatal head injuries
  • Being stepped on, sat on, or dropped by humans
  • Attacked by larger dogs during "play"
  • Grabbed by birds of prey (hawks, owls)
  • Escaping through small gaps in fencing
  • Hypoglycemia from missing meals
  • Anesthesia complications due to tiny size

Buyers MUST understand these risks. Many Yorkies live in constant danger from things that seem harmless. This breed is NOT suitable for families with small children or large dogs.

High-Risk Pregnancies

Yorkie pregnancies are extremely high-risk. C-sections are often required because puppy heads are too large for the tiny birth canal. Emergency C-sections at night can cost $3,000-5,000. Mothers can die from complications. Litters are small (1-4 puppies) and newborns are incredibly fragile. Hypoglycemia kills many puppies in the first weeks. 24/7 monitoring is required. Breeding Yorkies is not for beginners - it requires extensive experience and emergency funds.

Yorkshire Terrier Breeding Guidelines

Follow these essential guidelines for responsible Yorkshire Terrier breeding

Optimal Breeding Age

Male Yorkies

1.5 to 7 years

Female Yorkies

2 to 6 years

Toy breeds mature earlier but are fragile. Wait for complete development. Breeding lifespan shorter due to tiny size.

Health Testing Requirements

  • Patellar Luxation evaluation (OFA) - MANDATORY
  • Eye Examination (CERF/OFA) - Annual requirement
  • Bile acid test for liver function - Recommended
  • Heart evaluation - Recommended
  • PRA genetic test - Optional
  • Tracheal examination - Highly recommended
  • X-rays for Legg-Perthes - If indicated

Yorkies face many health challenges due to tiny size. Patella testing is critical for this breed.

Breeding Frequency

Females: Maximum once per year, 3-4 litters lifetime

Skip at least one heat cycle between litters

C-sections often required due to tiny size and large puppy heads. High-risk pregnancies.

Additional Breeding Considerations

  • Size Standards Critical: Breed under 4 lbs or over 7 lbs. Too small = health problems, too large = not a Yorkie. Maintain proper size.
  • Coat Quality Essential: Silky texture and proper steel blue/tan color required. Avoid woolly or cotton coats.
  • Buyer Screening Mandatory: Most people underestimate care requirements. Require contracts, educate about dangers, discourage impulsive buyers.
  • Emergency Fund Required: Breeders need $5,000+ emergency fund for C-sections and complications. Many litters cost more than they earn.
