Kennel Club recognized Pug coat colours in UK are – fawn & black. Fawn pugs can come in many different shades, ranging from a pale clear colour, a pale cream, to a rich apricot colour, and all the shades of gold in between.
Any other colours such as Brindle, White, Platinum, Black & Tan etc will NOT be 100% purebred pugs. Regardless of whether or not they have kennel club registration paperwork, these non standard colours have been achieved by unscrupulous breeders crossing pugs with other breeds. Such as French bulldog, bulldog and then falsely registering the offspring as purebred kc registered pugs in order to produce pups which look similar to pugs, but have different coat colours. These are often referred to as CNR Colour Not Recognised, because these colours do not naturally occur in the pug.
Pug Coat Colour Genetics & Mode of Inheritance
Every pug has two (a pair) of coat Colour genes’ that determines its colour. When we mate two Pugs, each parent will pass along one of their colour genes to the puppy, so each puppy is then born with its very own unique pair of colour genes. Fawn is a recessive colour gene, Black is a dominant colour gene. What this means is if a puppy was to inherit one black colour gene & one fawn colour gene the puppy would be black.
FAWN PUGS - If a pug is Fawn in colour, it will always, without exception have two fawn coat colour genes. = (f/f)
BLACK PUGS are a little different; as they come in two genetic varieties:
A DNA coat colour test can be done to determine what combination of colour genes a black pug has.
