You do and also quite possibly do not want to watch this collection of videos of dogs greeting soldiers returning home from our abysmal wars. Dogs! Soldiers! Hugging! Watch them all! (At the end, of course, you will be convinced of the superiority of cats, who would just be all like, "Oh you were gone for 18 months? Well, haaayyyyy, whatever.")

Or snakes, who wouldn't have had to eat the whole time you were gone.
This is 8 videos of dogs exploding. WIN
There is really nothing more viscerally pleasing than watching a really happy, excited dog.
I know. Just watching the epic battle between the competing impulses to have as much physical contact as possible with the human and to run around and wiggle and squeak. Oy.
And the cat would have the world's most stank-ass litter box for you to clean.
Rin Tin Tin K9 CUTE!!!
At least videos of cat reunions would not make me cry.
(To be fair, it was the one at the end with kids & parents, not the dogs, that did me in. Thanks, Awl)
The Awl owes me a new reputation as a cold bastard, for MAKING me watch this at work.
