A while back I had a movie and I can't remember the title, I'm hoping someone here can help me out.

I believe it was an independent film about a guy who had a girl living as a dog. Like he would keep her in a cage and take her on walks. I'm not sure if I got it here or if it was even in English.

Unfortunately that's all I can remember of the film. Thanks in advance for anyone who can help, sorry for my vague description.
