There are witnesses....the puppy CAN open the fridge door!! ...she can also open the front door (how freaky is THAT!)...Here are the tricks: 1. she nudges the seal on the bottom of the fridge door with her nose....2. the front door lock is not 100% ok (thanks to my nephew, back in our nightmarish era when he was doing drugs and used to sneak into the house at night to see what he could steal!)...and if you push the bottom of the door at a certain point, the door "bounces" back and the lock clicks open (unless the key is in the lock and the bolt is turned, which we only do at night, this is an enclosed neighborhood!)...
so, public apologies to my sis are in order!!

Of course, knowing that the puppy is THAT smart means that she CAN learn, only she REFUSES to learn what we want to teach her!! (As per my cousin, it also means she is a direct descentant of velociraptors!!)
