Harlequin Great Dane information

The Harlequin Great Dane color is an alternate color to Merle and one of the most identifiable color variations.

As mentioned earlier, this dog should have a white base color with irregular black patches well distributed throughout the dog’s body.

The uniqueness of this coat is made more interesting by the fact that no Harlequin Great Dane can be identical to the other.

This Harlequin Apollo of all dogs also has additional characteristics with some being deemed preferable.

Here are some of the main characteristics; 

  • Black patches should not be too large.
  • The patches should be balanced and not too many nor too few and can appear on the legs and chest as well.
  • These patches should be torn (have jagged edges) and should not be rounded.
  • A Harlequin Great Dane with a white neck is preferred.
  • It is preferred that no black hairs should show through the white base coat color.
  • This color variation may also have merle patches.

You can also get a mismarked Harlequin Dane giant but this should not be an issue if you don’t plan to show your Great Dane.

But what is the reason behind this rare coloration? Genetics

Harlequin Great Danes genetics

Several studies show this Harlequin Dane color is brought about by mutation of the Merle gene (M) in Great Danes. We could not be having these Harlequin giants without the merle gene.

To get a Harlequin Dane, both the dogs need one or two copies of the mutated Merle gene. This dilutes the base color with dark patches on the top. Also, this pattern cannot be expressed in Danes with red pigmentation or that are not marle.

It is also suggested that you can get a Harlequin Dane by breeding a Merle and Blue Great Dane.

However, the breeding of a Merle/Harlequin with a mantle Great Dane produces the largest number of show-marked harlequins.

Breeding two Harlequin Great Dane

Breeding two Harlequin Great Danes is highly discouraged as there are several health issues related to this. Doing this results in white puppies that often end up deaf or blind.

Mating 2 Harlequins does not also guarantee Harlequin puppies.

Even when harlequin offsprings are produced in a litter, there will be pups with other colors as 556 n the parents carry other color genes such as black, fawn, and so on.

For example, a litter of 7 puppies may have 1 to 2 merle pups, 2 to 3 harlequin pups, 2 white puppies (probably deaf), and 2 black or mantle pups.
