voiceover video

Hi guys, I recently posted my first video of my 2 dogs, they are yorkies :) I was just wondering whether I should have music in background (like it currently has) or should I rather talk over the footage?

Hey guys, I recently started adding voiceovers to my cooking videos (instead of just adding text overlays to my vids), but my friend watched it and said I sounded monotone. It's just my regular voice though! What do you guys think? Should I go back to doing the text instead of the voiceover...
