I bet your dog was still happy to see you though when you showed back up! That is the definition of unconditional love right there, and the big difference between a dog and a spouse.
If you would have tied your wife to the bumper of your truck and taken off for a couple of days she probably wouldn't have been happy to see you when you came back.
You douche bag, however do not deserve the love of your dog. You deserve the wrath of a bunch of internet do-gooders. I think you should give your dog away, and re-examine yourself.
You are the reason why, the more I am around people, the more I like dogs.
Lastly, your lucky your dog wasn't ripped to shreds and eaten a live by wolves, or savagely chewed apart by a grizzly sow with cubs. That area ain't Colorado, you city slicker. There are wild things all around.
Shape up dickweed!
