How old is Molly again? Gauge is almost 3 and hes been out of his crate around 8mths. He will still chew on things if they are left out. Never walls or anything but shoes, books papers whatever. He hasn't done it in sometime then the other day I came homeand he shredded my husbands hat. I blame it on the weather and not getting as much exercise as he normally gets. When he went thru his teenage phase he was about 7months but his only lasted a few weeks. He acted like he forgot everything I taught him.
