Dog question

[Red Devil]

Put him on a treadmill with a rawhide hanging in front of him and let him wear himself out. Just joking of course. My pup just turned a year old and she would chew the cords off of everything and chew the moulding up when left alone. My wife bought some spray that she sprays on stuff she doesn't want chewed up and started buying rawhide bones or pig ears and it seems to have helped. She also gave her a pair of my old tennis shoes. But I feel the older they get, the more they calm down.
