Per her foster mom:
Whitey is a hoot!  She is the most vocal of the three.  She is very alert to and confident in her surroundings.  Of the three pups, she is the one that wants to play with the big dogs who are a good 75lbs bigger.  She will either "play up" to play with Kelly or "play down" to play with Inky.  She loves to split her her time leisurely in the flower bed with playing chase with her buddies Inky and Kelly.  She is game for anything.  Like Kelly, after she's done playing, she loves to be held like a baby and have her belly rubbed.  (I heart Whitey)
