Thirty bitches undergoing routine neutering were used in an assessor-blinded trial of the postoperative analgesic effects of pethidine and carprofen administered either together or singly. The level of analgesia was assessed by visual analogue scale (VAS) scores for pain and sedation and by nociceptive mechanical threshold testing. The two drugs administered together, and carprofen alone, provided good postoperative analgesia as assessed by vAs scoring. Pethidine alone did not provide postoperative analgesia of sufficient duration.
