Really clever idea. It really fits the theme and it has wonderfully frustrating controls. It felt a little bit weird to yell all the commands, although I was alone.
It gets a little repetitive because it's always the same and the gate is just getting smaller and smaller. Maybe some other game mechanics would be nice. Maybe some collectibles or so.
Btw. I managed to get out of the fence on the Level 4 (might be wrong here). I did so on the fence which only had one horizontal bar and let the wolf run at the maximum speed. Maybe you want to fix that if you continue on the game.
All in all, solid game jam entry.
PS: How many levels are there?
