This is Mosi, one of the canadian wolf pack at the UK Wolf Trust. I took this photo while out on a members walk. Her and her sister were howling to communicate back with the other packs in their enclosures nearby.
From this angle she almost has a bit of a grizzly bear look going on!
They were each on a chain (a heavy duty leash really) for the walk and you can see the two handlers on the chain behind.
