Assistance dogs are dogs trained to perform specific tasks that mitigate the effects of a disability and that are placed with the person they assist. The category comprises guide dogs for people with visual impairment, hearing dogs, mobility assistance dogs, medical-alert and psychiatric service dogs, and dual-purpose animals combining roles [1][2]. Placement imposes welfare demands met only through adequate rest and recovery, predictable daily routines, and sufficient opportunity for recreation outside working hours [3], while the finite working life obliges providers to plan retirement with animal welfare and handler dependence both in view [4].
