The L locus affects the length of the hair coat of dogs due to a DNA variant in the FGF5 gene.
The variant causes that a hair growth in the follicle is not stopped, so dogs develop longer hair. Long hair is inherited autosomal recessively – dogs with long hair must inherit this variant on both alleles of the gene.

Collie smooth
Gentle and devoted herding dog with a noble outline and a short, close-fitting coat. Within the family it is affectionate and patient with children, typically reserved with strangers but not sharp. It originates from Scotland and shares roots with the Rough Collie, yet offers easier maintenance. Intelligent and sensitive, it responds best to calm, positive training and enjoys learning tricks and dog sports such as agility and obedience. It needs regular exercise and mental engagement; its watchful nature can make it a bit vocal at times. The short double coat is easy to care for—occasional brushing is enough, with more attention during shedding. Responsible breeding pays attention to health, including eye examinations and sensitivity to certain medications. Well raised, the Smooth Collie is a reliable, active and elegant companion for an active household.
