Animal-assisted therapy programmes use companion animals to support human mental health and wellbeing, but the welfare of the therapy animals themselves requires structured protection.
Animal-assisted therapy welfare requires the same attention as the human therapeutic outcomes the programmes produce. A dog working in a care home that visits multiple residents with dementia for several hours without rest may be experiencing chronic social and sensory overwhelm. The welfare signals -- lip licking, yawning, whale eye, low body posture -- are readable by trained observers but missed by participants focused on the human interaction. Accreditation standards that include animal welfare monitoring, working hour limits, handler training in stress recognition, and retirement criteria when animals show persistent stress responses are essential for ethical therapy animal programmes.
