If you come across a dog that appears to be lost or a stray the first thing you should do is stand quietly at a distance and observe it just to make sure he does not appear injured or terrified. If you approach too quickly, the dog may bolt or worse, may be aggressive towards you.
One of the biggest fears of a dog owner is if their beloved pet runs off or escapes and does not return or worse still is stolen. If your dog is lost you need to act quickly.
