Yes, so sad but true.  I was told by a friend that she knew of a lady who had her Yorkie outside on a leash.  An owl swooped down, grabbed the Yorkie and tried to take off in the air with the poor Yorkie in the owl's grasp. 
 
The lady was on the end of the leash pulling as hard as she could and probably panicking to know end and the owl let go.  The Yorkie did have some wounds but were treatable.  The Yorkie healed just fine. 
So, even outside on a leash we need to be careful!
