We've all seen dogs go nuts when they see their owners, but this pooch's reaction may be the best we've ever witnessed.

This dog was so fired up it actually passed out. It turns out the dog was seeing the woman in the video for the first time in two years, which clearly explains its enthusiasm.

The pooch passes out around the 20-second mark and it's only for a brief spell before it recovers.

The dog was taken to a vet who said everything checked out fine.
