This dog is a teenager.......
This means that his hormones are flying around, he needs training, and plenty of exercise, both physical and mental.
The stealing things is not his fault.......trust me, there are very very few dogs out there who wont steal food if its left lying around. You need to train yourself and your family NOT to leave ANYTHING in his reach (yep, i DO know how hard that is, ive got a lurcher!)
Chewing is another thing that dogs need to do......he NEEDS to chew, if the wrong things are lying around, then they will get chewed......simple as, dont leave stuff around if you dont want it chewed.
The peeing/pooing on beds, trashing house......
Id be pretty willing to bet that this dog is rarely left alone for any length of time....brilliant for him most of the time, but what about when he DOES have to stay on his own? Suddenly he is all alone, all his family are gone. Imagine if you left a 6 year old on his own, suddenly, a particularly clingy 6 year old, who had never been without his mum an dad before?
This dog needs to be TAUGHT to be alone...he doesnt have the coping skills naturally, being alone is a very unnatural thing for a dog to deal with.
This has to be done slowly and patiently, rewarding the dog with things like filled Kong toys whilst he is alone, using a DAP diffuser, slow short sessions of just five minutes at first, building up to longer periods.
A crate would probably be a good idea, although expensive, and you will have to take time out to train him that the crate is a lovely place to be, and NOT a punishment. If you get him used to a crate, by feeding him in there, giving him treats in there etc, then you wil have somewhere u can safely leave him, without fear of him damaging anything.
Do not fall into the trap of thinking that your dog has messed on beds or wrecked the house to get at you in anyway, its not spite, its distress at being left.
The only other thing i pick up on is that if you do value a mattress more than a dogs life, then it might well be better to rehome the dog.....sorry, but to me my dogs are more important than any soft furnishings!
