Effect of neutering timing in relation to puberty on female dog behaviour-A scoping review.

BACKGROUND There are contradictory findings in the literature relating to the effects of timing of neutering on bitch behaviour that make decision making regarding neutering timing difficult. METHODS A scoping review was designed to identify and chart the evidence on the effect of neutering timing in relation to puberty on the behaviour of female domesticated dogs. A protocol was registered, and literature searches were conducted in CAB Abstracts, Medline and Web of Science. Studies were reviewed against the inclusion criteria. Data on study and population characteristics and behavioural outcomes were extracted for the final included studies. RESULTS A total of 1048 publications were reviewed; 13 were retained for inclusion and charting. Only one of the two studies that classified bitches as pre- or postpubertal presented results for the analysis of behaviours. The remaining 11 studies classified bitches by age at neutering. LIMITATIONS Since the scoping review searches were conducted, further relevant studies may have become available. The search strategy may not have identified all available literature; however, databases were used that provide high levels of coverage of veterinary literature. CONCLUSION This scoping review identified a lack of evidence to document the impact of neutering bitches before or after puberty on behaviour.
