WATCH: Beau & Theo are back in a new video so cute you will squeal out loud

If you need a Monday pick-me-up, I've got the perfect thing. Remember Beau and Theo, the adorable baby and puppy pair who captured everyone's hearts with their ritual of napping side-by-side? Well, they're back and even more heart meltingly sweet than the last time we saw them … if that's even possible.

After Jessica Shyba's photo of her son, Beau, with their dog Theo became a viral sensation, the California mom was able to turn the cute project into something much bigger. In addition to using the pictures to create an awesome children's book Naptime with Theo & Beau, Shyba has also started creating videos revolving around the pair's amazing friendship. And it's so cute, it almost hurts. Seriously, there's no way you won't be in a good mood after watching this. Check it out after the jump!

The three-minute clip follows Beau and the rest of the family from when they first adopted Theo and throughout parts of their blossoming friendship into current day. You can see how the two became best pals and start doing everything together–from first meeting to playing together on a beach and in their backyard to and of course, to the ritual that started it all, the simultaneous napping. Theo even jumps in the bath with Beau!

The whole thing is honestly too cute for words. I don't think anyone can resist the sight of these two together. I just hope Shyba keeps documenting their adventures together for the rest of the world to see!
