Note the Time and Place
When you realize your dog has gotten loose, determine his last known location and the time. If he slipped out of your home or yard, put a bowl of food at the door he uses and start calling him.
Form a Search Party
Head out the door and ask your neighbours to be on the lookout for your dog and to alert you, if they see your pet. It is always best to look for your dog when you realize they are missing before taking any other action. It also helps to have several people looking for a dog. Get friends and family in a search party, fanning out in an organized way from the last location your dog was.
Bring food to entice your dog and hand out extra leashes to search party members. Refrain from chasing from afar; this may cause your dog to run farther away. Always keep your safety in mind, as you are likely to feel frantic. Be cautious around busy streets and use flashlights if you are out at night.
