Uncommon colour? - Page 1

I was looking some puppies and I found one puppy who called me attention because he has the end of the legs of white colour. It is the third picture. (He has pedigree)

There is nothing uncommon about this pup..........Some pups are born with white on the tips - but they fade...............Pictures seem to be one at a certain age then one older...........what is your question.
