I hate to be the one to say this.... but adolescence is never. truly. Gone. Just wait until Peggy (and everyone else's) is about to turn, let's say, 7 years old. Out of NOWHERE comes a playful, puppy type "YIP!", followed by sheer energy induced running around the room, with lots of grrr's and err's and even some I'm-so-tough snarl-like sounds coming from the throat. Then up on the couch, on the table...which has never been allowed... over to the chair, picks up the little pillow and tosses it off the chair, then on the floor to the toy box: reached way down inside that and pulls out a toy not seen in years, and continues said behavior until you are laughing so hard you can't breathe, and your dog comes to rescue you. It has happened to me at least a couple of times a year lol. They just truly, never do, grow up all the way.
