Colour Dilution Alopecia in Dogs
Colour Dilution Alopecia is a low-severity dermatological condition that can affect dogs of all ages and breeds. Colour dilution alopecia is a hereditary skin condition associated with the dilute coat colour gene (dd). Abnormal melanin distribution in hair shafts leads to progressive hair loss and recurrent folliculitis in blue or fawn-coloured dogs. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 6 months - 2 years. Early signs to watch for include progressive hair loss on trunk, dry scaly skin, recurrent skin infections, and affects only dilute-coloured coat areas. When treatment is required, costs are estimated at £200-£800/year depending on severity, location, and the specific intervention needed. Colour Dilution Alopecia has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
