While this looks bad, it can be repaired. If there is enough excess cord to still reach your power source after removing the damaged section and splicing the two "good" ends together, you can attempt to fix this. Obviously, you must turn off the power to the IC40 before attempting any repair. There are several methods to splice the good pieces back together, but, no matter how you do it, the repair must be waterproof. I recommend using solder seal butt joints with heat shrink wrap built-in. When the wires have been soldered back together use heat shrink tubing around the whole cord to cover the repair. As a deterrent to your puppy place a hard plastic cord organizer around the cord and sprinkle some chile powder on it. Good Luck!
