Long coat · Langhaarigkeit · L-Locus · FGF5 gene variant · Long-haired coat
This is a natural genetic variation affecting the FGF5 gene, also known as the L-locus, which controls the hair growth cycle in a dog's skin. Instead of signaling the hair follicle to stop growing at a standard length, this variation allows the growth phase to continue, resulting in longer fur. It is inherited in an autosomal-recessive manner, meaning a dog must inherit the variant from both parents, and it is a normal physical characteristic rather than a medical disease.
Owners will notice the development of longer, softer fur starting in puppyhood as the adult coat begins to grow. This longer hair is typically most prominent on the ears, tail, and the back of the legs.
No medical treatment is required for this harmless cosmetic trait, resulting in a medical cost of 0 EUR. Owners should expect routine, lifelong grooming and brushing to maintain coat health and prevent matting.
