Travel is stressful for most companion animals. Evidence-based preparation and management significantly reduces welfare harm during necessary journeys whether by car, plane, or other transport.
Pet travel welfare is primarily determined by preparation rather than management during the journey. Animals that have been positively conditioned to carriers, vehicle motion, and travel routines from early life experience significantly less stress during necessary journeys. Animals thrust into unfamiliar transport situations without preparation experience acute fear responses that compound with duration. The welfare principle — minimal necessary travel, maximum preparation for unavoidable travel — applies across species. International travel involving quarantine creates extended welfare stress that should be considered carefully before pets are relocated internationally.
