Twenty dogs were anaesthetized, but did not undergo surgery (control group). 22 dogs underwent laparotomy and ovariohysterectomy (surgery group). Dogs in the control and surgery groups were further assigned on a random basis to either oxymorphone or placebo groups (group O or P). Dogs in group O received oxymorphone (2.5 mg/msuperscript 2, i.m.) as a pre-anaesthetic and 6, 12 and 18 h later, while dogs in group P received isovolumetric doses of sterile saline. The dogs were videotaped for 24 h after anaesthesia, during which time a handler interacted with the dog once each hour. At each interaction the handler recorded a sedation and a pain score, using a numerical scoring system. Interactive and non-interactive behaviour was observed and quantitated by a single observer using the videotapes. Surgery resulted in an increase in pain score, sedation score and time spent sleeping. During interactions with caregivers, greeting behaviours were decreased after surgery. Differences between surgery group dogs given analgesics and those given placebo drugs were readily measured using quantitative behavioural measurements, but were not apparent using the numerical scoring system.
