The growth of emotional support animal (ESA) designations has created a system frequently exploited, raising welfare concerns for both animals and the humans who need them.
ESA welfare involves a genuine paradox: the human health benefit of the human-animal bond is real and documented, but forcing unsuitable animals into stressful public environments to provide it causes animal welfare harm. A dog experiencing severe anxiety in an aircraft cabin is not providing therapeutic comfort effectively — it is suffering. Welfare-conscious ESA practice requires honest assessment of whether the specific animal is suited to the specific role and environment. Regulatory frameworks need to distinguish between genuine service animals with public access rights and companion animals providing home-based emotional support, while protecting the human benefits of both.
