Oh my, what stories so far. My three dogs now have been pretty good. No huge amount of destruction. Other dogs though...
A weimaraner we wound up giving up due to these issues...smashed up/chewed/dented three metal kennels he had due to anxiety issues not only causing damage to the kennels but to himself, tore up carpeting in our old apartment that we had to pay several hundred dollars to replace, chewed up our house's bedroom carpeting, completely destroyed two window's blinds, chewed up a 3 foot section of fabric on a sectional we had, destroyed a pair of Dior sunglasses, and knocked over a pumpkin pie cooling on the stove that took 6 hours to bake which fell face down on the floor. His last destruction was a plastic kennel with metal window sections that he proceeded to chew and scratch less than a foot section into and somehow managed to squeeze himself out of. The act that nearly drove me to a loony bin, however, was when he was left out and got into all the cabinets and tore up every single boxed item inclusive of pasta and rice and it was ALL over the living room. He also chewed up a huge jar of peanut butter which was mixed in with the pasta. I pretty much sat down, cried, then went to bed to deal with it later, lol. Needless to say he wound up finding a new family that could hopefully tolerate this behavior.
We also had a german shephard (didn't get rid of him due to bad behavior though) that was afraid of pillows. One day while left unattended not in his kennel he tore up 4 of them and there was nothing but pillow fluff all over the bedroom. He also got into a bag of three musketeer mini candy bars and managed to eat them, wrappers and all, which we induced vomiting but he was okay.
