DOODS & COAT COLOURS

Brindle / Merle / Mosaic

A brindle has a pattern of dark and light striping in the fur.    There are black, chocolate, red & silver brindles. A merle dog has a base coat of a solid colour with patches and mottled areas of other colours. A mosaic coat has patches of colours.  It is not a colour variety carried by genes.  It is rare and likely caused by a colour gene mutation. K locus alleles determine the colouring pattern of a dog's coat.  A brindle pattern will be expressed if the dog has one kbr allele and no KB allele. M locus alleles determine whether a dog expresses a merle pattern to its coat.
