Blue Merle

The merle colours were very common in the early days of the breed. They were so common that at a certain point in time breeders avoided them for being too common. This has gone too far resulting in merle being quite a rare pattern these days.

Breeding merles requires a bit of knowledge of genetics. When two merle dogs are mated about 25% of the pups will be homozygous for Merle (so called 'double merles'). These dogs are almost white and/or have very pale markings. Chances are that they are not even born. Pups that are actually born are often blind, deaf and/or sterile. Allowing such dogs to be born is not generally acceptable. Mating a merle to a non-merle already produces 50% merles, so breeding merles is not very difficult.

More information on the genetic background of coat colours can be found at Genetics of coat colour and other exterior properties.

Blue has a blue merle coat with tanpoint markings. His colour must be described as blue merle tri; something most stud books cannot handle (yet).

Tac has classical markings with a balanced merle pattern. Contrary to Blue (see above) who has blue eyes, Tac views the world with beautiful brown eyes; both eye colours are permitted in merles.

Gwen has a darker merle pattern. She also has brown eyes, with a blue spot in her left eye. The merle patterns also influence the eye colours.

"Spin it again Luke" (owner and photo: Yvette Zmaila) has a rather coarse merle pattern on his body, but a much finer pattern on his head. His white blaze will become a bit smaller in the future and his nose will be darker.
