Dog that roots like a pig

Over the years we have had 3 dogs that have loved to root around in the dirt like pigs do. Their noses are covered in dirt when they are finished. I am surprised that they don't get blackheads on nose with all that dirt. Of course the reason they don't is the fact they have long tongues and they can clean their noses with it.

Of course most of our dogs just love to roll in something very smelly too......but that is another story.
