My dog chewed a plastic bag containing the special proprietary cables for a computer display/input switch. I think she just wanted the bag and the cables were collateral damage, because she's never chewed cables on their own before or since.
They refuse to sell the cables separately so it made the device itself useless unless I buy another one for like $100. Ended up not bothering and giving up on having a peripheral switch because I refuse to give them that much money again just because a $10 set of cables broke and reward their shitty business practices. I just manually switch the actual display and USB cables when I want to control another computer.
Also blew my mind just how strong a bite force even a small breed dog has. She totally crushed the metal casing surrounding the plug and shattered the plastic molding in the less than one minute she had it. I can't even do that with my teeth (then again I've never tried).
