It is these tasks which will make them distinct and specialised assistance dogs. In the US, an assistance dog handler may be asked if they have a disability, and what tasks the dog does to mitigate that disability as the only two legal questions to ascertain that a dog is indeed an assistance dog.[9] The tasks that an assistance dog prospect will learn depend on the disabilities that their current or future handler has and there is therefore almost no limit on the types of tasks a dog can be trained to. These may vary from picking up dropped items and taking laundry out of a washing machine to interrupting self-harming behaviors to providing deep pressure therapy for an autistic person.[10]
