Former US President Lyndon B. Johnson's
White Collie, Blanco (below)

Blanco was born on July 19, 1963 and registered as Leader Blair Jamie of Eden.
He was a gift from a little girl in Illinois to the President, in December 1963.
He was given to a Kentucky doctor and his wife before the president left office.
Blanco died in September 1974.

President Johnson always shook hands with Blanco when he left or returned to the White House.

Understand how the genetics work...

A tricolour Collie is being used in our examples below.

These tricolour dogs could be any of the colours, such as
sable, blue merle or sable merle.

The gene for white-factoring does not affect the colour of the dog's
coat, except for producing a greater amount of white in the coat, if it
is present.

***

+ =

A White Collie bred to another White Collie
will produce a litter of White Collies.  The amount of white in the coat of
the resulting litter will vary from all white coats, to coats with patches of colour on the body.
The head of all Collies, even White Collies, should be normally coloured.  There may or may not be
white on the face, which is acceptable.  The coat colour may be tricolour, like our examples here, or sable,
blue merle or sable merle.  The white gene does not affect the colour of the dog, only the amount of white
in the coat.  There may be a lot of white, or just a little.

***

+ =

A White Collie bred to a non-white factored Collie
will produce only white-factored Collies.  All the puppies
in this litter will carry the gene for white factoring, but, none of the
puppies will be White Collies, and none will be non-white factored.
The puppies from this litter could produce White Collies if bred to a
White Collie or another white-factored Collie.

***

+ = &

A White-factored Collie bred to a Collie that does not carry a gene for white-factoring
will produce both white-factored puppies and non white-factored puppies.
Approximately half of the puppies produced from this type of
breeding will carry the gene for white factoring.

***

+ = & &

A white-factored Collie bred to another white-factored Collie
will produce White Collie puppies, white-factored puppies
and non white-factored puppies.

Approximately two thirds of the puppies from this type
of breeding will carry the gene for white factoring.

The White Collie is a healthy dog as sables, tricolours and blue merles,
and is on its way to win more and more popularity.

The White Collie has nothing to do with a double-merle which may be defective.
