My mal, Frosty Claire was inside her fenced yard, but sometimes had 
to be chained  because her nickname was Houdini. Our yard allowed for 
her to go into a barn that had a hole in the side of it. One day when 
I was coming home from work I noticed that the chain went into the 
hole and then straight up. Of course I panicked and threw open the 
doors of the barn only to see the chain in a web of 
"shed-barn-like-things" and Frosty holding on to a pole for dear life 
so she didn't hang herself. The minute she saw me she let go of the 
pole and was left hanging in mid-air gagging, but still managed to 
wag her tail. Needless to say, I did an amazing accrobrat act to climb 
over everything in the barn to release her. She was fine and went 
running into the house for dinner like nothing had happened.
