The merle poodle is distinguished by its unique coat pattern, a striking combination not traditionally found in purebred poodles.

If you encounter a poodle with a merle coat and blue eyes, exercise caution; these traits suggest that the lineage may include another breed, as the merle pattern is not a natural poodle trait.

It’s essential to consider the health implications associated with the merle gene, including the risk of serious complications such as deafness and blindness, particularly in dogs with a double merle pedigree.

What is a Merle Poodle?

What is a Merle Poodle?

Merle Poodles possess a unique coat pattern that distinguishes them from the typical solid-colored Poodles.

The merle gene, which is not originally found in Poodles, causes a distinctive mottling effect, resulting in a marbled appearance with patches of color.

This pattern can vary and may include spots, dots, and dashes.

Understanding Merle Genetics:

  • Semi-Dominant Gene: Merle is a semi-dominant gene, meaning it does not naturally occur in Poodles and must be introduced from another breed.
  • Breeding: To produce a Merle Poodle, one parent must carry the merle gene.
  • Masking Effect: The E Locus gene, responsible for red, apricot, cream, or white coats, can mask the merle pattern, complicating detection.

Health Considerations:

  • Dogs carrying the merle gene can be predisposed to certain health issues, including sensitivity to certain drugs and increased risk of sensory impairments.
  • MDR1 Mutation: This genetic trait affects the blood-brain barrier and can cause adverse reactions to common de-wormers.
  • Hearing and Vision Impairments: There’s an associated risk of deafness and blindness, especially in dogs inheriting two copies of the merle gene (known as double Merles).

Registry Status and Breeding Ethics:

  • Merle Poodles are not officially recognized by major kennel clubs like the AKC or UKC due to the introduced non-Poodle gene.
  • Ethical considerations arise since breeding for this trait can lead to health problems and goes against breed standards.

When observing a Poodle with the merle pattern, it’s essential to be aware that despite its appearance, it comes from a mix with another breed.

As such, Poodles with blue eyes or the merle coat pattern do not align with the dark-eyed ideal stated in breed standards.

For those seeking a Poodle, it is advisable to consider the implications of the merle pattern on the dog’s health and authenticity.

Merle Poodle: Facts, Origin & History

Merle Poodle: Facts, Origin & History

Merle Poodles represent an uncommon yet captivating variety of the Poodle breed, distinct for their speckled coats and remarkable intelligence.

Despite their striking appearance, it’s important for you to understand the breed’s background and its standing within formal canine registries.

Formal Recognition of Merle Poodles

The Merle Poodle is not officially recognized as a separate breed by major canine organizations like the American Kennel Club (AKC) or the United Kennel Club (UKC).

Moreover, the merle coloration, a result of selective breeding, is not a traditional color pattern in Poodles according to the AKC’s breed standards.

Originating in Germany and standardized in France, the parent breed, Poodle, is distinguished by its coats which can be solid colors such as apricot, black, blue, brown, cream, gray, red, silver, and white.

Your interest in Merle Poodles should be accompanied by an understanding that because they fall outside these established breed standards, their unique coloration doesn’t receive formal recognition despite the pattern’s appeal among some dog enthusiasts.

Merle Gene and Genetics

Merle Gene and Genetics

The Merle gene in Poodles is responsible for a distinctive coat pattern characterized by patches of diluted pigment and is a subject of fascination regarding canine genetics.

When you hear about the Merle gene, it’s commonly referred to in the context of color inheritance—particularly for its visible impact on a dog’s coat.

It’s essential to be aware that the gene is not specific to any one breed and can occur in various dog breeds.

Genetic Mechanism: The Merle gene is a dominant gene, meaning that only one copy of the gene is necessary for the merle pattern to manifest in your Poodle’s coat.

However, it exhibits incomplete dominance, which means that dogs with one copy of the gene (Mm) will show a milder merle pattern than dogs with two copies (MM).

Health Implications: While the Merle gene can lead to an attractive coat:

  • Health Risks: It’s linked to several health risks. These include potential hearing and vision impairment, particularly in ‘double merles,’ dogs with two copies of the Merle gene. The likelihood of these issues underscores the importance of responsible breeding practices.
  • MDR1 Mutation: The MDR1 mutation is another health concern related to genetics, affecting drug sensitivity.
  • Hypothyroidism: While not directly linked to the Merle gene, diseases like hypothyroidism are prevalent in the breed and need to be monitored.

DNA Testing: To prevent health problems, DNA testing can be done to determine a dog’s Merle status.

This assessment is crucial for breeders to ensure that they are not breeding two Merle dogs, which could result in double merles with higher susceptibility to health complications.



When you encounter a Poodle with a merle pattern, it’s characterized by a unique mottling of colors which results in patches and varying shades.

The presence of the merle gene is responsible for this distinct appearance and it signifies variations not just in the coat, but potentially in eye color and skin pigment as well.

This gene, identified as SILV or PMEL, expresses in an incomplete dominant manner meaning a single copy can influence the dog’s coat pattern.

Purebred status often hinges on breed standards and recognition by official clubs and entities such as the American Kennel Club (AKC). Merle Poodles are considered purebred, but this specific coat pattern may not be recognized across all Poodle breed standards.

Therefore, while the dogs themselves are purebred Poodles, the merle coloration may disqualify them from standard classifications in certain breed organizations.

Merle is, in fact, more than a cosmetic trait; it’s linked to significant biological functions which can include hearing and vision variations.

Because of its inheritability, the breeding of merle-patterned dogs, including Poodles, should always be approached with an understanding of the genetic implications—particularly because specific alleles of the merle gene can be associated with certain health risks.

In your search for a Poodle, you might note the merle pattern does come with premium pricing, reflective of its rarity and the particular breeding practices that may develop these coats.

Careful and responsible breeding practices are paramount to mitigate potential health concerns directly linked to the merle gene expression.

It’s essential to consider that while merle Poodles showcase this attractive and less common coat pattern, they should be valued and cared for with the same informed approach as any Poodle, prioritizing health and well-being over aesthetics.

Can you breed a merle Poodle to a merle Poodle?

Can you breed a merle Poodle to a merle Poodle?

Breeding a merle Poodle to another merle Poodle is technically possible, but it is highly discouraged due to the risk of serious health problems in the offspring.

The merle gene is responsible for creating a distinctive pattern in the coat, which can be visually appealing.

However, when two merle Poodles are bred together, there is a 25% chance for each puppy to inherit two copies of the merle gene, known as “double merle.”

Double Merle Puppies: Potential Health Risks

  • Vision Impairment: There may be a higher likelihood of blindness.
  • Hearing Issues: An increased risk of deafness is present.
  • Skin Problems: Lack of pigmentation can lead to sensitive skin.

Inheritance Pattern in Merle Breeding

  • If two merle Poodles are bred, there is a:
    • 25% chance the puppies will be double merle.
    • 50% chance the puppies will be merle.
    • 25% chance the puppies will not carry the merle gene at all.

To ensure the well-being of the puppies, it’s advised to breed a merle Poodle with a non-merle Poodle.

This pairing greatly reduces the risk of the health issues associated with the double merle genotype.

It is important for breeders to conduct proper genetic testing before breeding to identify merle genes and avoid producing double merle puppies.

Responsible breeding practices are key to ensuring the health and safety of Poodle puppies.
