Objective
To assess the efficacy of alfaxalone as an anaesthetic induction agent for dogs aged less than 12 weeks.

Materials and methods
The study group comprised 25 juvenile dogs aged less than 12 weeks that were presented for surgical desexing. Dogs were aged by dentition, examined and weighed prior to premedication with acepromazine, atropine and morphine. At 20–30 min after premedication, animals were anaesthetised with intravenous alfaxalone administered to effect, using a target maximum expected dose of 2 mg/kg. Dogs were intubated and anaesthesia was maintained with isoflurane in oxygen administered with a non-rebreathing system. Subjective measures of anaesthetic quality and vital signs were recorded from enrolment to recovery. Descriptive and comparative statistics were used to analyse and present collected data.

Results
The mean (± SD) dose of alfaxalone for induction was 1.7 (± 0.3) mg/kg body weight. Subjective measures of anaesthetic quality indicated acceptable induction, maintenance and recovery standards. Measured cardiovascular and respiratory parameters were well maintained.

Conclusion
Alfaxalone in 2-hydroxypropyl-beta-cyclodextrin (Alfaxan®) is a suitable injectable anaesthetic induction agent for dogs aged less than 12 weeks requiring anaesthesia.
