I have a puppy who is a couple of weeks away from being 6 months old. We've had him since he was 8 weeks old but we're having real trouble with leaving him in on his own for any amount of time. Any other training we've done with him has been really successful but not this. We tried when he was younger to get him used to being in alone but always came back to a disaster zone and he's only got worse as he's gotten older. He chews everything he can get hold of (I know this is typical puppy behaviour) and when there's nothing around for him to chew he'll pull up the carpet or lino or just chew a on wall. He also does the toilet even if only left in for half an hour and even when he's just been out to the toilet before we leave. I don't want to end up one of those people who can never go anywhere because of their dog and I'm hoping some people on here might have some good advice on ideas to improve the situation.
