El Perro Del Mar ("The Dog Of The Sea" if you translate it from Spanish) is a musical project of Sarah Assbring, founded in Sweden back in 2003.
Cute and melancholic pop sound is probably the essence of El Perro Del Mar. "Do The Dog" appeared originally on some B-side release in 2005, but now it's included in her debut reissue. It's actually a great idea to celebrate a milestone of your project with a debut reissue including a whole bunch of rarities and previously unreleased tracks. The track has a slight hint of reggae, but retains this typical indie pop sweetness. So good!
