Blue Dog Syndrom (CDA Dog)

Blue dog syndrome is caused by the dilution mutation (dog's coat, but also the skin, have a dark to light grey colour). This can also lead to severe health problems such as colour dilution alopecia (CDA - dilution colour-related hair loss). This results in a dry, dull and poor coat quality with hair loss and skin lesions increasing with age.
