Destructive huskies

Question
I have a 10 month old 56 lb husky TITAN; i work from 9-5 and we have a good routine daily. We get up at 6 go for a run/walk for an hour; sometimes he will wear a backpack with 2 water bottles 750mls so he feels like he is working. i use a halti to get him to stop pulling so hard but he still likes to try especially if he sees a bird or another dog. I know he sleeps for the majority of the day and manages to hold his toileting most of the time although i still leave out a pad just in case and he does sometimes use it. I come home most days at 2pm on lunch after leaving at 8 and take him out for potty break and a 15 min walk, then most days he goes in his crate for the remainder of the day sometimes till 7pm from 3pm. is this too long? i feel bad some days although he is fine and very excited bouncing off the walls when i come home to let him out....the reason i do this is because if i leave him out he will eat the carpet at the front door, eat his leash, take the stuffing out of the cusions of the sofa pull off the seat pads and eat them and generally become destructive for the remainder of the day if left out of the cage. Some days if i cant come home at lunch and this is what he will have done along with defecating on mostly the pad and newspaper but sometimes on the carpet as well due to the fact he walks when he toilets. He is a good dog and I am working on getting him to listen to me more than he used to....is there any pointers you can give to stop destructive behaviour and still toileting in the house? is the crate my only option? I was thinking of buying some DAP spray to help him relax more when he is left for the day. Its nice to sometimes have a lunch to my self and not come home.please help.

Answer
Crating is the best option overall until he grows up some more and calms down a little with age.  (Mainly, Sibes don't calm down, but they find better outlets for their energy.)  4-5 hours in a crate is not a problem at a time, and it encourages them to sleep during that time anyway.  The important thing is that when you are available and at home, you'll want to make sure he's getting plenty of interaction, play time and exercise.  If you do that, you should do fine.

As for his excitement during the day, I generally just gave one toy or so in the crate - something to chew on and that usually helped them relax during the day.  Some dogs are more high-strung, but I generally avoid the sprays and drugs if it can be helped.
