Cross Breed Dogs: Breeds that Can’t be Crossed

In 1911 Fédération Cynologique Internationale (FCI) was founded in order to encourage and promote breeding, to protect the keeping of dogs, to support free exchange of cynological information. Nowadays it is an international federation of kennel clubs with headquarter in Thuin, Belgium. They also make a decision about crossing breeds.

At conference of General assembly of FCI the following decisions concerning crossbreeding were made:

  1. FCI allows to cross different types or varieties of breeds only when there is a need to improve a gene pool or in case of a critical state of health of breed, i.e. if there are problems in cultivation because of insufficiency of dogs population in breed.
  2. Crossbreeding can be made only after the receiving permission from the countries that are the homeland of breed, the countries providing patronage over the breed.

Crossbreeding of different types or species is allowed in order to prevent or treat health problems or to remove defects which cause different diseases. Thus it is necessary to remember:

Species of dogs of the different size of one breed: When crossbreeding it is necessary to consider the size of the bitch that it could be a natural childbirth;

Long-haired species: long-haired species can lose its characteristic, because it is recessive;

Dogs with a Merle-Factor (mottled patches): it is forbidden to cross two dogs with Merle-Factor because a quarter of puppies will be homozygous, i.e. will have hereditary fatal diseases or health problems.

Belgian Shepherd and Dachshund:  it shouldn’t cross long-haired and stiff-haired species – there is a risk of getting an atypical texture of hair.

Poodle: it shouldn’t cross ash (silver) color with apricot or red – there is a risk of getting atypical colors.

Great Dane: it shouldn’t cross two dogs with harlequin color – ¼ puppies will be homozygous, with fatal diseases. Also it shouldn’t cross dogs with harlequin color with dogs of other colors, except for the black colored species. The harlequin color is genes of black and white and Merle colors.

German Spitz: it shouldn’t cross gray color with others. Also it shouldn’t cross a brown colored dog with dogs of other colors, except for the black colored species.
