My Husky would chew out of a welded wire fence.  It looked like chainlink, but the wires were just spot welded instead of inter-twined like a chainlink fence is.  Poor college student and it was all I could afford. 
 
Took me about a month to figure out how she was getting out of the yard; she would escape but the roommates dog didn't. One day I noticed that she had shiny, silver teeth... She figured out that she could bite the welds and break them, and she only needed to break 4 in a row to be able to squeeze out. The fence snapped back into shape right away so you couldn't tell it was broken - hence the roommates dog never followed her out. Roommate and I tied spent the weekend with a roll of wire tying shut the broken welds and reinforcing the entire fence.
