Guide dog in the context of Visual impairment

A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons, and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather.

The history of working animals may predate agriculture as dogs were used by hunter-gatherer ancestors; around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants.

A working dog is a dog used to perform practical tasks, as opposed to pet or companion dogs.

Definitions vary on what a working dog is, they are sometimes described as any dog trained for and employed in meaningful work; other times as any dog whose breed heritage or physical characteristics lend itself to working irrespective of an individual animal's training or employment; and other times again it is used as a synonym for herding dog.

The Golden Retriever is a Scottish breed of retriever dog of medium-large size. It is characterised by a gentle and affectionate nature and a striking golden coat. It is a working dog, and registration is subject to successful completion of a working trial. It is commonly kept as a companion dog and is among the most frequently registered breeds in several Western countries; some may compete in dog shows or obedience trials, or work as guide dogs.

The Golden Retriever was bred by Sir Dudley Marjoribanks at his Scottish estate Guisachan in the late nineteenth century. He cross-bred Flat-coated Retrievers with Tweed Water Spaniels, with some further infusions of Red Setter, Labrador Retriever and Bloodhound. It was recognised by the Kennel Club in 1913, and during the interwar period spread to many parts of the world.

A mobility aid is a device designed to assist individuals with impaired movement. These devices help people walk, maintain balance, or get around more easily.

Mobility aids include walking supports like canes, crutches, and walkers for those with limited walking ability, as well as wheelchairs and scooters for individuals who cannot walk or need assistance over longer distances. For people who are blind or visually impaired, tools such as white canes and guide dogs offer essential support. There are also aids designed for use within buildings, such as stair lifts and transfer devices that help users move between floors or from one position to another.

The Labrador Retriever, also known simply as the Labrador or Lab, is a British breed of retriever gun dog. It was developed in the United Kingdom from St. John's water dogs imported from the colony of Newfoundland (now a province of Canada), and was named after the Labrador region of that colony. It is among the most commonly kept dogs in several countries, particularly in the Western world.

Labradors are often friendly, energetic, and playful. It was bred as a sporting and hunting dog but is widely kept as a companion dog. Though content as a companion, these dogs are intelligent and require both physical and mental stimulation. It may also be trained as a guide or assistance dog, or for rescue or therapy work.
