Understand how the genetics work...
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
coat, except for producing a greater amount of white in
the coat, if it
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
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
The puppies from this litter could produce White Collies
if bred to a
White Collie or another white-factored Collie.
White-factored Collie bred to a Collie that does not carry
a gene for white-factoring
will produce both white-factored puppies and non
Approximately half of the puppies produced from this type
breeding will carry the gene for white factoring.
white-factored Collie bred to another white-factored
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
The White Collie has nothing to do with a double-merle
which may be defective.
