Umm Stella may know how to open the freezer..LOL
My one year old gsd still gets treats every time I call him in from outside. I figure if I make come very special thats the one command he will always listen too. My son has been teaching our dog to open the refrigerator . He wants to teach him to get a beer. Well, my dumb son left the rag on the fridge door.
Dex is outside barking at the countless birds, possums so I call him inside while im in the kitchen cooking. he comes in opens the fridge door and grabs himself a mouthful of hot dogs (his usual special treats) out of the fridge. Needless to say the rag has to go.
Do NOT underestimate these dogs LOL
