I think it's chasing Brodie that helped Olive learn to get up the stairs.
The girls follow their mommy up the stairs, too.
Poor little Clyde can't climb the stairs yet. :(
They are getting so big! We have started to take them outside on a daily basis to see if we can start potty training them, and they seem to like to get out in the sun. Before I know it, they won't be little puppies anymore!
