The Blue Merle Australian Shepherd’s unique appearance stems from a specific genetic mutation affecting the distribution of melanin. This genetic pattern creates a marbled effect that distinguishes them from other coat variations in the breed.
Distinctive Coat Pattern and Genetics
The merle gene (M) creates a mottled pattern by diluting random patches of the base coat color. The primary features of a Blue Merle Australian Shepherd’s coat include:
- A gray or silver base color with darker patches
- Black spots or patches scattered throughout the coat
- White markings on the chest, face legs or collar
- Copper or tan points appearing on specific areas: eyebrows cheeks legs
The merle gene affects each dog differently, resulting in these genetic characteristics:
- Dominant inheritance pattern (M)
- Random distribution of pigmented areas
- Varying patch sizes from small specks to large spots
- Different intensities of blue-gray coloration
Eye Color Variations
Blue Merle Australian Shepherds display remarkable eye color diversity due to the merle gene’s influence on pigmentation. Common eye color combinations include:
- Complete heterochromia (two different colored eyes)
- Partial heterochromia (multiple colors in one eye)
- Blue eyes
- Brown eyes
- Marbled or split eyes
- Single solid colors in each eye
- Segments of different colors within one eye
- Flecks or spots of varying colors
- Combinations of light blue darker blue brown

Health Considerations
Blue Merle Australian Shepherds face specific health challenges linked to their genetic makeup and coat pattern. Understanding these health aspects helps provide optimal care and early intervention when needed.
Genetic Health Issues
The merle gene associated with the blue merle coat pattern creates several potential health concerns:
- Double Merle Syndrome: Breeding two merle carriers results in a 25% chance of deaf or blind puppies
- Eye Abnormalities: Increased risk of colobomas microphthalmia iris defects
- Hip Dysplasia: 3.2% prevalence rate in Australian Shepherds according to OFA statistics
- Collie Eye Anomaly: Affects 2.5% of the breed population
- MDR1 Gene Mutation: 50% of Australian Shepherds carry this drug sensitivity gene
- Epilepsy: 5.7% occurrence rate in the breed
Preventive Care
Essential preventive measures maintain optimal health for Blue Merle Australian Shepherds:
- Genetic Testing: DNA panels identify carrier status for MDR1 IVDD CEA
- Regular Eye Exams: Bi-annual ophthalmologist checks monitor vision health
