Help, does anyone recognize this episode?

I saw an episode a few years ago that I'm now trying to track. It only has 3 characters in it: a woman, a man and a dog.

The woman brings the man back to her apartment with comments about how she's become reluctant to get serious with anyone since her former boyfriend mysteriously disappeared. She then leaves to change clothes, leaving the man alone with the dog.

The dog acts annoying to the man, who eventually puts the dog out onto the balcony which overlooks a cliff. The dog appears to be depressed and jumps off the balcony. The man runs to check, finds the dog on the cliff face several feet below the balcony. He tries to capture the dog, but of course the dog tricks him into falling over the cliff's edge. The dog then removes any evidence of the man (like his jackets, etc), and is there to console the woman when she discovers another "mysterious disappearance."

Does anyone recognize this?
