Sharing is caring!

Blue merle Pomeranian breeders have made great improvements to the merle Pomeranian. The quality has improved very quickly and merle colored Pomeranian of exquisite type are now a regular sight in the show ring.

The Pom breed now have champion merle Pomeranians. A wonderful achievement by clever, knowledgeable and dedicated Pomeranian owners/exhibitors and breeders.

While most merle Pomeranian puppies are incredibly beautiful, there is important merle genetic information that is invaluable to merle Pomeranian breeders and people looking for blue merle Pomeranian for sale.

History of the Merle Pomeranian Dog

Newcomers to the world of Pomeranians should also be aware that the Pomeranian merle is also a very recent addition to the Pomeranian world.

To be fair the same could be said about most of the other Pomeranian colors, but we must mention that the stud book, way back when Queen Victoria imported Marco and other Pomeranians from the continent, was not a closed stud book.

The Pomeranian as a dog breed was really only in early stages of development. In the very early 1800’s we did not have the rainbow of Pomeranian colors available now.

From the “Sportmans Cabinet” published 1803 “this breed is termed the Pomeranian or Wolf-dog, and the colour is referred to as being “mostly of a pale yellow or cream colour, and lightest in the lower parts; some are white, some few black, and others, but very rarely, spotted.”

Many long term Pomeranian breeders have expressed concerns about the Merle Pomeranians sudden appearance on the scene. A simple fact is that merle is caused by a dominant gene. So a merle dog must have at least one merle parent.

What Exactly is the Merle Color Pattern?

Merle is a color combination in dogs’ coats. It is a solid base color (usually red/brown or black) with lighter blue/gray or reddish patches, which gives a mottled or uneven speckled effect.

Although most breeds that can have merle coats also typically have white markings (such as around the neck, under the belly, and so on), and often tan points (typically between the white and the darker parts of the coat), these are separate colors from the merle; some dogs do appear completely merle with no white or tan markings.

Merle may also alter other colors and patterns other than the usual red or black. These other possible combinations such as brindle merle or liver merle are not typically accepted in many Pomeranian breed standards.

Popular merle pattern combinations include the chocolate merle Pomeranian ( also called a brown merle),  red merle Pomeranian and the very rare and beautiful lavender merle Pomeranian. 

Breeding Merle Pomeranians

The use of lighter colored Pomeranians in a merle breeding program is not a desirable practise. Attempting to breed a cream merle Pomeranian is not recommended nor is the use of sables.

Breeding a merle colored Pomeranian to a sable will produce a sable merle Pomeranian. The sable merle Pomeranian could easily be mistaken for a normal sable and bred to another merle. This type of mating can produce defective whites.

In addition to altering base coat color, merle also modifies eye color and coloring on the nose and paw pads.

The merle gene modifies the dark pigment in the eyes, occasionally changing dark eyes to blue, or part of the eye to be colored blue. Since merle causes random modifications, however, both dark-eyed, blue-eyed, and odd-colored eyes are possible. Color on paw pads and nose may be mottled pink and black.

To breed for merle, it’s wise to breed to darker colors because the merle gene affects those dark colors to produce the pattern.

This means the recommended Pomeranian pairing colors are:
Black, chocolate and blue and each of their tans. You can also breed merle solids with parti Pomeranians in any of the chosen colors.

Don’ts – It’s unwise to breed merle with white, cream, or extreme white piebald pattern parti-color Pomeranians.

Genetics of the Merle Pomeranian

MM: Merle dog from breeding merle to a merle. ( MM merle Pomeranians have a high risk of health problems, including eye and hearing issues i.e. being blind and deaf.)

Mm:  Merle dog with one non mere parent. ( For those wishing to breed merle Pomeranians this is the preferred mating).

mm: None merle dog.

Genetic Problems Associated With the Merle Gene

A Pomeranian blue merle Breeder and owners of merle Pomeranians need to be aware of the following risks associated with this Pomeranian color pattern.

Blue Merle Pomeranian Health Problems:


The association of merle coloration and deafness is well established.

Eye Defects:

Veterinary studies have been conducted on merle dogs since 1971. Studies on the eyes of these dogs have revealed the following results. All the normal mm dogs were devoid of eye anomalies while all the MM animals had a series of eye defects.

These included the absence of the tapetum lucidum, lack of retinal pigment, a rudimentary lens, microphthalmia, microcornea, microcoria and other more minor conditions. Mm cases also had similar eye problems although less severe in most instances.


Veterinary research done over a 30 year period on merle dogs revealed impairment of sperm production in both merle dogs (Mm) and dogs from merle to merle matings (MM).

Breeding Merle to Merle Pomeranians

Merle Pomeranian to Merle Pomeranian should yield 50% of the progeny merle, 25% black and 25% white. The whites produced from these mating’s will be both deaf and blind.” Merle is actually a heterozygote of an incomplete dominance gene.

If two such dogs are mated, on the average one quarter of the puppies will be double merles (“double dilute”) and a high percentage of these double merle Pomeranian puppies could have eye defects and/or be deaf.

Knowledgeable merle Pomeranian breeders who want to produce merle Pom puppies mate a  Pomeranian merle with a non-merle Pom dog; these breeding’s will produce merle Pomeranian puppies.

Final Thoughts on Merle Pomeranian Dog

Please note the merle color pattern in Pomeranians is not an approved Pomeranian color in most countries ( apart from the United States of America). The merle is now an accepted color pattern as one of the AKC Pomeranian color patterns.
