Make funny noises when you are trying to take pictures lol then keep snapping really quick as many pictures as you can and pick the one you like most Hope that helps!
Oh Potter; I HAVE tried make noises, call her name, even offer treats..... She's more interested in chewing off the clothes, jacket, ect.......... And, I do snap a LOT of PIX (most contain no puppy, because she runs/rolls away).
This PIC would have been awesome for the Ball, if only she been dressed!
