Brings back rotten memories! Had a pup that chewed shoes but was trained not to...unfortunately the pup just traded chewing objects, he started chewing the wires under the fender wells of the vehicles. The first to suffer damage was my pickup, then the car...had to rewire turnsignals tail-lights etc. Dog wound up in a pen, after being evicted from the backyard when the kids couldn't keep him from chewing up toys. Finally found a new home for him about fifteen miles away....he came back home 4 days later. Took about a year and a half, but he finally stopped the chewing business, and got on with another 14 years of living before we lost him. Well worth the overall cost when he outgrew his chewing stage.
