Need help finding a song by music video
 

Hello, I'm new here.
I was listening to a song on MTV yesterday (I think it was on Music Rulz) and I kinda liked it, but I don't know its name or the artist. I'm clueless, I can only describe what I saw in the music video:

The action was unfolding in a forest of some kind, in the woods...among trees. There was a man on a horse, a woman dressed in some kind of white dress, somehow similar to a wedding dress. I don't remember ever seeing the woman riding the horse, she was just walking through the forest, spreading her arms at times and looking up, if I remember well. There was also a dog hopping around in the forest, together with the woman and the rider. And the last detail I remember is that the song wasn't sung in English, it could've been Spanish, but I'm not entirely sure. Any input would be greatly appreciated. Thanks in advance!
