It's hard on families when mom or dad are away on deployment serving their country. We videos all of the time of dads or moms surprising their kids when they come home from a long deployment.

This is something that we're seeing more and more of though - dogs reacting to their owners coming home after being gone for months or even years. 

This Marine had been deployed for 10 months, and his dog Rocky couldn't contain his excitement about his dad coming home.

Granted, my dog is happy to see me after I've run to the store for a few minutes because he's sure that I've left him forever, but I've never seen him this happy!
