We have had this same problem with our 3 month old guy Memphis. He chewed my daughters USB cord for her camera, my cell phone charger and the phone line for the fax machine. Thankfully none of these were plugged in to anything but we have to watch him like a hawk. I will look forward to when this phase ends and it's not like he doesn't have enough of his own toys to keep him busy not to mention playing with our other dogs.
