More poop questions!

After reading the other thread on pooping...(LOL, I'm so immature sometimes...[;)]) I wanted to post about something that really drives me crazy about my ten month old puppy.  When she "does her stuff" she ALWAYS walks around while she does it.  Poo, pee, whatever.  She starts in one spot, but then she walks around, squatted down, while she goes.  This is not only...really gross to see...[:D] but it's a pain in the butt!  When I have to pick up poop it's like following Hansel and Gretl's trail of bread crumbs through the forest...[:D] only stinkier...[:'(] [:D]
 
Any idea WHY she does that or if it's possible to stop the behavior?  [:)]
