Cachorrinho is a Portuguese-language pop song by Brazilian singer Kelly Key, whose title translates as little puppy. The track comes from the bright, danceable pop that made Key a household name in Brazil in the early 2000s, and its simple, affectionate chorus helped it stick in listeners' memories long after its release. Online, short clips of the song have found a second life as a soundtrack for dog videos, pet montages and nostalgic Brazilian pop edits, where the familiar melody instantly signals something cute, playful and light-hearted.
