When's the last time your dog was this excited to see you?

Casey was so happy to see her family member after two years away, she faints from excitement when they're finally reunited.

The video, which was posted to YouTube on July 24 and has gotten more than 14 million views, left some concerned about the 14-year-old pooch’s health. The schnauzer was taken to the vet, and she's OK.
