My Bitch had a litter of pups, in which we kept 1, he is 14 weeks old now, and been really good, peeing & pooing on the paper, sitting before treats, we really thought we were getting progress with him.

Until this week, he was left in the house with his Mum for 2 hours, we came home to find he had chewed a huge hole in the carpet.

We got the carpet sorted & locked them both in a room, the next time we went out, only to come home & find, he has managed to chew through the plasterboard & had completely destroyed his bed????

Why has he suddenly decided to start this behaviour, and how can we get him to stop???

HELP!!!!!!!! I have 4 dogs & have never had this problem, with any of the others, so I am taking bad???
