Sarah McLachlan Lightens Up In Audi Super Bowl Teaser Ad To Save 'Doberhuahua' (VIDEO)

Sarah McLachlan, the singer whose tear-jerking pet-abuse ads have earned millions for the ASPCA, is showing off her lighter side for the Super Bowl.

In a teaser ad for Audi, McLachlan speaks in the same pleading tone as her memorable PSAs and asks viewers to help the misunderstood "Doberhuahua."

A "Doberhuahua," presumably part-Doberman, part-Chihuahua, has "a heart as big as your head," she sings.

What this fictional pup has to with Audi, we'll have to wait for the big game to find out. But McLachlan's already a winner for poking fun at herself.
