Wild animal use in circuses has been progressively restricted globally due to welfare concerns; the evidence for harm is compelling.
Wild animals in circuses are unable to express natural behaviours, experience chronic stress from travel and performance, and historically have been trained using aversive methods. The welfare case for banning wild animal circus use is strong and has driven legislative change globally. Retired circus animals require specialist rehabilitation and long-term care; sanctuaries face challenges reintegrating animals that have been kept in inappropriate conditions. Domestic animal circus use raises more nuanced welfare questions — horses and dogs can derive enrichment from trained activity when positive reinforcement methods are used and welfare needs are met, but the travelling lifestyle imposes constraints that must be managed carefully.
