So Sky has been wrecking the house this past couple of days including tearing bags of rubbish inside the house and outside the house! She has been walked and fed so dont know why she is ripping house apart...

She has chew toys an all but has them in shreds. Could she be teething at 2 and half years old lol

It sounds like you have a bored and frustrated Husky on your hands. Without knowing your dog or your habits, I have to ask. How long of a walk are you taking her on, do you take her for more than one walk per day? Is she crate trained? Does she have a "hard" chew toy, such as a Kong-type toy? Is she being played with or challenged?

Out of all the dogs I have ever had, Huskies are by far the most confounding. I have been blessed with a relatively calm Husky. However, I have seen the results of a bored Husky. They can seem malicious and vengeful, but they really aren't. Being intelligent, stubborn, and VERY high energy dogs will lead them to find a way to vent their energy.

I really don't think that at 2 years your dog is teething.

I would agree with what Mark said.

Basic answer:

Up the exercise you are giving your dog this will help get out all that energy.

Get some good high quality chews such as antlers or raw bones that take some time and energy.

Seasons can affect the energy level of your dog too. Sadly, humans and huskies don't really agree on the weather. The colder it gets the more energy my husky seems to have.
70 degrees and he's willing to walk as much as I'll take him, but he's not really craving it.
30 degrees and he wants all the walks I'm willing to do and more.
-20 degrees and he wants to run a marathon while I'd rather not even look out a window.
