I rescued one of those (like the one on the left). He was my first dog and a real pain. I truly think that someone “threw him away” in our neighborhood knowing that some dummy (me) would take him in. Not an easy dog to live with — willful, sneaky, etc.
I used to confine him to the kitchen when I was out of the house and he could sneak through the baby gate so that he could poop and pee on the rugs. So, I would block his exit with my typewriter case. That little devil actually jump up on the kitchen table and pooped on the keyboard of my typewriter when I had to dash in to the newspaper to turn in my “copy” before deadline.
After he died, I had to have the bottom 8 inches of all of the mahogany furniture, including the piano pedals, refinished do to his “accidents”.
But, he was cute, as long as he was the center of attention.
Our experience has been the exact opposite of yours. About the only thing our old girl has ever done wrong was to drop a load on the couch where my wife sits after we put her in a dog kennel while we went on vacation. We still think that was intentional on her part.
My daughter has one that she rescued out of a shelter. I am sure she was thrown away for her bad behavior too. That dog will poo on stuff out of revenge, she first confined her to the kitchen too but if my daughter leaves dirty dishes in the sink she will jump up and drag/knock the dishes onto the floor...once she managed to get the kitchen faucet turned on and flooded the kitchen. My daughter now kennels the dog when she is at work to stop her shenanigans. I did not know Schnauzers were so ornery!
