Hi
I have a blue roan 10 months called Bertie who is a little
at times. He digs enormous holes in the garden (thought I had foxes at first), he tries to eat everything he can get his mouth on and has destroyed a couple of rugs. He likes to turn them over and chew them from the underside and as my husband has never been a great dog lover it has been difficult.
Anyway, we decided to focus only on his good points and keep an eye on him all the time and this has really helped. If we go out he is in a small utility area with a baby gate where he can't damage anything. We have a baby gate in the hall so he can only go upstairs (to our study) if we are with him. If he is really hyper, we will put him in his cage to calm down (usually when the cat's chase him).
I would try to keep him in one part of the garden where it doesn't matter too much what he does. This is the first year I haven't visited the garden centre buying plants (no point Bertie tries to eat them all).
We now only buy indestructible balls, etc. otherwise they last 5 minutes. I bought three (99p each) brightly coloured plastic watering jugs from Ikea. He loves them. It takes ages for him to chew them. He's had all my dustpan and brushes.
I think he will learn what is acceptable to you and grow out of it (he is only a puppy). If you can find someone else with a young dog that he can play with to wear him out a bit that might help.
Another point is food. I think some of the additives in supermarket brands can make dogs more hyper.
To be honest, I think all this is totally normal for a puppy
Just one question, what are you doing when he's chewing the house and garden to bits?
