Hi Robbie,
She's very confident and doesn't seem to notice that the Sibes are twice her size - I think she believes she is an Akita. She holds her own easily.
She was incredibly affectionate as a puppy, then went through a stand-offish phase for just over a year, and is now back to being a serious cuddle-muffin, although she can be a bit aloof with strangers.
We love the breed, but we're a bit full up at the moment, so we'll just make do with Missy.
I found some more photos of our "guard" dog:
Here she is guarding the sofa on behalf of our Anya and Alaska (one of the SHWA rescues)

and this is her guarding .......... the sofa again - keeping our boy Maverick safe.

and here she has got off the sofa to guard Kira (another SHWA rescue) on the grass.

The huskies are wonderful to live with (as long as you are prepared for constant vigilance - they can get up to a lot of mischief in a very short time) and we wouldn't be without them.
