Australian Shepherd Dog Breeding: Complete Guide for Responsible Breeders

Breed Overview: The Versatile Australian Shepherd

The Australian Shepherd, despite its name, is an American treasure developed in the Western United States. These brilliant herding dogs combine intelligence, athleticism, and devotion in a medium-sized package. Originally bred for versatile ranch work, today's Aussies excel in everything from herding to agility, search and rescue to therapy work, proving their adaptability and eager-to-please nature.

Breeding Guidelines and Standards

Health Testing Requirements

MDR1 Gene Mutation - Critical Information

The MDR1 (Multi-Drug Resistance 1) gene mutation affects approximately 50% of Australian Shepherds. This mutation causes sensitivity to certain medications including:

• Ivermectin (heartworm prevention at high doses)
• Loperamide (Imodium)
• Certain anesthetics
• Some chemotherapy drugs
• Specific antibiotics

Testing reveals three possible results: Normal/Normal (clear), Normal/Mutant (carrier), or Mutant/Mutant (affected). All results allow for safe breeding when paired appropriately.

Merle Breeding Guidelines - CRITICAL SAFETY

NEVER breed merle to merle. This pairing produces 25% double merle puppies with:

• Congenital deafness (partial or complete)
• Blindness or severe vision impairment
• Microphthalmia (abnormally small eyes)
• Sun sensitivity and skin cancer risk
• Possible organ defects

Safe merle breeding combinations:

• Merle × Black tri
• Merle × Red tri
• Merle × Black bi
• Merle × Red bi
• Solid × Solid (produces no merles)

Breeding Age and Frequency

Optimal Breeding Age - Males

2 to 8 years (peak fertility 3-6 years)

Optimal Breeding Age - Females

2 to 6 years (best outcomes 2-5 years)

Female Breeding Frequency

Maximum once per year

Skip at least one heat cycle between litters

Lifetime maximum 3-4 litters

Recovery Period

Minimum 12 months between litters

Working Lines vs Show Lines

Australian Shepherds have distinct breeding lines with different characteristics:

Working Lines

• Higher drive and energy levels
• Stronger herding instincts
• Often smaller and more agile
• May have less coat
• Intense focus and work ethic
• Best for active working homes

Show Lines

• More moderate energy levels
• Fuller coats and striking appearance
• Often larger bone structure
• Calmer temperament for family life
• Still intelligent and trainable
• Better suited for companion homes

Breeding Costs Breakdown

Natural Bobtail Gene

Approximately 1 in 5 Australian Shepherds are born with naturally bobbed tails due to the T-gene mutation. Important breeding considerations:

• Natural bobtail is a dominant gene
• NBT/NBT (double bobtail) can be lethal in utero
• Test before breeding two natural bobtails together
• NBT/normal breeding produces 50% natural bobtails
• Tail length varies from completely absent to 3/4 length

Australian Shepherd Pregnancy and Whelping

Gestation Period

63 days average (range 58-68 days)

Average Litter Size

6-9 puppies (average 7)

Birth Weight

10-16 ounces per puppy

Eyes Open

10-14 days after birth

Weaning Age

Socialization Critical Period

Australian Shepherds require extensive early socialization due to their naturally reserved nature with strangers:

• 3-14 weeks: Critical socialization window
• Expose to 100+ different people
• Various environments and surfaces
• Other animals and dogs (safely)
• Household sounds and activities
• Car rides and handling exercises
• Prevent fear periods and reactivity
