You may have seen those homecoming video on the web of soldiers returning home to their families. They are great to watch and hard to fight off crying like a lil' bitch. You may have also scene the videos of soldiers returning home to their pets. The following video doesn't involve a soldier, but is a homecoming video that involves a dog so happy it passes out.

According to the Youtube description

A pet dog's reaction to a family member returning home after 2 years... which in fairness is 14 years in dog years.

The family member was living and working in Slovenia, and didn't return home to Murrysville, PA last year, because her whole family (except Casey) came to Bled for her wedding.

Sidenote:
The schnauzer, Casey, was taken to the vet, the vet saw the video, and everything is fine with her. No worries.
