Yes, the day has arrived; Chanel, the world's oldest living dog, has turned 21 years old today according to aol.com! Yay!!! On top of this spectacular milestone in her lifetime (is she technically allowed to drink?), she's also a model! Frightened and shaking (aww...), she posed for the cameras and clearly looks like a star. In fact, she's probably the oldest working model around in the industry today! :P So let's all give Chanel a hand, happy birthday cutie! :)
