Most dogs are recovered within a two mile radius, as even the largest and most agile will not run for a long time in a straight line.
Where your dog goes will depend on personality, but as a rule of thumb an outgoing dog will be looking for other dogs and for other humans who are friendly and likely to give comfort, food and shelter. Gardens and public parks will be likely places to look. A shy or older dog which is not so trusting will hide in familiar places or in bushes and under cars.
Ideally get the help of others to search nearby while you stay still and call out in a normal voice. If someone else searches with another friendly dog on the lead, even better. Dogs are social creatures and will be attracted to the other dog.
A dog that is panicked, scared or worried about being told off is less likely to return. Bring along your dog’s favourite toy, or another noise that makes them come running. Dogs can hear sounds from very far away and may come if they hear a comforting sound. Shaking a treat bag or something else a dog knows means food, can help too.
If you do see your dog, do not chase them. They may become frightened or playful and run away. Instead, coax the dog toward you with toys or your dog companion, and by talking in a soft voice the way you would to a young child.
