Why do my three golden retrievers lick my friends knees when they are wearing shorts

In the summer three friends who are girls wear short shorts and whenever they wear short shorts my dogs lick their knees why is that?

I have dogs and they lick my knees too. I think its because of the salt in our skin and they are getting flavour out of it.
