Emotional support animal vs assistance dog
Is an emotional support dog an assistance dog? No. Here is the difference in UK law, side by side, and why no paperwork changes it.
The short answer. No, an emotional support dog is not an assistance dog. In the UK an assistance dog is trained to assist a disabled person and is defined in the Equality Act 2010. An emotional support animal is any animal whose company supports its owner’s mental health, and it has no legal definition, no training requirement and no official register.
The short version
An assistance dog is defined by what it has been trained to do. An emotional support animal is defined by what it means to its owner. UK law recognises the first and not the second, and no document moves an animal from one column to the other.
What makes a dog an assistance dog
Section 173 of the Equality Act 2010, in the part on taxis and private hire vehicles, defines an assistance dog as a dog trained to guide a blind person, trained to assist a deaf person, trained by a prescribed charity to assist a disabled person with epilepsy or a disability affecting their mobility, dexterity or co-ordination, or of a prescribed category trained to assist a disabled person with a prescribed kind of disability. Every part turns on training, and only dogs are included.
Assistance Dogs UK is the umbrella body for accredited assistance dog charities. People with dogs trained by its members are given an ADUK booklet or card. ADUK is clear that this is not a register: it says there is no register for assistance dogs in the UK, and that it is not possible to register a dog with anyone, including ADUK.

| Renting in England | GOV.UK says refusal would usually be unreasonable where the landlord knows the tenant needs an assistance animal | A pet request that must not be unreasonably refused. No special rule |

Where emotional support animals stand
The Equality and Human Rights Commission says emotional support animals are not defined in the Equality Act 2010. GOV.UK’s pet travel guidance says dogs that only provide emotional support are not usually considered recognised assistance dogs. And the Civil Aviation Authority says recognised assistance dogs on flights do not include dogs that solely provide emotional support.
What an emotional support animal can have is the protection that comes from its owner’s circumstances: a pet request in a private tenancy in England, or a request for a reasonable adjustment where its owner is disabled. The EHRC says it may be a reasonable adjustment to allow a disabled person’s emotional support animal, depending on the facts. That is weaker than the position of an assistance dog, and it is honest to say so. Emotional support animal law in the UK.
If you need a trained dog
If what you need is a dog trained to perform tasks for you, an emotional support animal letter is the wrong route. Start with Assistance Dogs UK and its member charities. If what you need is evidence that your existing animal supports your mental health, a doctor’s letter is the right route, and it costs £49.
