Most Beardies pale to some degree. The amount they fade has no apparent relation to the colour they are, to how dark they are as puppies nor to how dark they will be as adults. You can see the paling start around the eyes or on the legs where the colour meets the white or on the tail as early as 7 weeks in some puppies. Others don't start to pale until later and some can do it quite rapidly when they're in late puppyhood. Generally, the most faded stage is around a year old.
Many dogs fade out so much that the white markings are indistinguishable from the colour.
By the age of 2, most Beardies have started to put themselves back together again, though it will still be a couple of years before you have a mature dog. By 2, they'll have a coat, though ii won't be very long or full. The hair stays out of their eyes. Your family will even begin to believe you got a real Beardie after all. Some two-year old dogs may even be showable.
