What Service Dogs Are, Why They Matter and What They Can Do

Trained for about two years, these dogs guide people who cannot see, alert owners who cannot hear, and can even smell an illness coming

A service dog — known in many countries as an assistance dog — is a dog that has been specially trained to support one person with a disability. Unlike a pet, a service dog has a job: it lives and travels with its owner and helps them do everyday things that would otherwise be difficult or dangerous. The bond between dog and owner is so close that trainers describe them as a working team.

The best-known service dogs are guide dogs for people who cannot see. Walking ahead of the owner in a stiff harness, a guide dog stops at kerbs and stairs, steers around obstacles and finds doors and crossings. The first schools for guide dogs opened in Germany in the 1920s, and today guide dog organisations work in dozens of countries around the world.

Hearing dogs do a similar job for people who cannot hear. When the doorbell rings, a fire alarm sounds or someone calls the owner's name, the dog makes contact with its nose or paw and leads the owner to the sound. At home, that means small daily tasks become easier; outside, it can prevent serious accidents.

Some of the most surprising service dogs work with their noses. A dog's sense of smell is thousands of times more sensitive than a human's, and dogs can be trained to recognise the tiny changes in body smell that come before certain medical problems. A medical alert dog can warn its owner minutes before trouble starts, giving them time to take medicine, sit down or call for help.

Other service dogs act as an extra pair of hands for people who use wheelchairs or have difficulty moving: they open and close doors, press buttons, pull off socks, fetch the phone and pick up anything their owner drops. Because this support is essential, the law in many countries allows service dogs into shops, restaurants, offices and planes — places where ordinary pets are not welcome.

Becoming a service dog is hard work. Training usually takes about two years, from puppy lessons to advanced skills, and preparing one dog can cost tens of thousands of dollars, which is why many are raised and trained by charities. Labradors, golden retrievers and German shepherds are the most common choices because they are calm, clever and eager to please. Not every dog passes: only the most patient and confident finish the course.

There is one simple rule for everyone else. A service dog in its vest or harness is at work, so do not pet it, feed it or call it, however friendly it looks. Let the dog concentrate — someone's safety depends on it.
