Vet is short for veterinary or veterinarian, which comes from Latin veterinarius, "of or belonging to beasts of burden and draught," from veterinus, "of draught, of beasts of burden." The earlier sense was "to submit to examination or treatment by a veterinary surgeon," hence "to subject to thorough appraisal."
