Microchipping companion animals dramatically increases the likelihood of reunion after loss, preventing the prolonged suffering of strays and the grief of owners and animals separated indefinitely.
Animals lost without identification face days to weeks of stress, hunger, and danger before being found or dying. Animals impounded at shelters may be euthanized if not reclaimed within a holding period. The psychological distress of animals separated from their homes and human companions represents significant welfare harm. Animals that are reunited with their families avoid this suffering, and microchips are the single most effective tool for achieving reunion. The brief discomfort of microchipping is vastly outweighed by the lifetime welfare benefit of guaranteed identifiability.
