If you own a dog, you probably already know the joy of standing outside in freezing weather as your dog sniffs for what seems like hours to find the perfect spot to poop. What you may not know is: It's probably your fault. According to Dr. Marc from the Broadway Veterinary Hospital in Boise, Idaho it's likely that you have inadvertently trained your dog to hold out as long as he can to avoid ending the outdoor activity. If you, like many busy dog owners, have gotten into the habit of ending your dog's time outside as soon as he does his business, you have reinforced the notion that the longer he takes to do his business, the more fun he will have.

Other theories, of course, include the thought that your dog is scoping out the area for the smell of predators - or the mark of another dog's territory - before he can relax and take care of business. Which you choose to believe is up to you, but I'm inclined to believe my dog simply enjoys torturing me late at night. (Photo: jbelluch via Flickr)
