My Springer Spaniels have eaten the subwoofer wires quite a few times. I wrapped them in loom and rubbed a bar of soap on it....didn't work. Next , I went to Pet Supermarket and bought "fooey". Some disgusting spray that is super bitter...it worked. No more chewed up wires. Do not use keyless locks on your coindoors. One of my dogs opened up my NF coindoor with his paw, stuck his head in and took out some new plastic protectors I got from laserrific , and a small motorcyle. Chewed up the motorcycle, and left the plastic protectors , as they laid to flat to the tile floor to be picked up.
