Answer

Performs specific trained tasks that mitigate a person's disability — which is the legal and practical distinction between an assistance dog and a pet that provides comfort. The tasks are the point.

What they are actually trained to do:

Guide dogs, navigating around obstacles and stopping at kerbs and steps.

Hearing dogs, alerting to doorbells, alarms, timers and a person's name.

Mobility assistance dogs, retrieving items, opening doors, pressing buttons, removing clothing and providing balance support.

Medical alert dogs, detecting changes preceding seizures, blood sugar drops in diabetes, or severe allergen exposure — apparently by scent.

Autism assistance dogs, providing anchoring and interrupting behaviours.

Psychiatric assistance dogs, performing trained tasks such as interrupting dissociation, room searching, or deep pressure therapy on cue.

The distinction that matters legally. An emotional support animal provides comfort by its presence without task training. In the UK it does not have assistance dog access rights, and this differs from some other countries — which is a frequent source of confusion and conflict.

The access rules in the UK:

Service providers must make reasonable adjustments for disabled people under equality law, which includes allowing an assistance dog into premises where dogs are otherwise excluded — shops, restaurants, taxis, hotels, hospitals.

Refusal is generally unlawful discrimination, and taxi and private hire drivers have specific duties with limited medical exemption.

Food premises rules do not prohibit assistance dogs.

There is no legal requirement for identification — no mandatory badge, harness or certificate. Many are accredited by recognised organisations and carry ID, but asking for proof and refusing without it is not a lawful basis for exclusion.

What the public should do: do not distract, feed, stroke or make eye contact with a working dog. A dog interrupted at the wrong moment can cost someone their safety. If a dog approaches you insistently while alone, it may be seeking help.

Businesses can ask what tasks the dog performs, and should train staff rather than improvising.
