Does Neutering Stop Aggression in Dogs? What the Science Says

“Aggression toward Familiar People, Strangers, and Conspecifics in Gonadectomized and Intact Dogs” (Frontiers in Veterinary Science) – This large questionnaire-based study found no effect of neutering on aggression toward familiar people or other dogs, and only a small increase in stranger-directed aggression for dogs neutered between 7–12 months. Aggression toward Familiar People, Strangers, and Conspecifics in Gonadectomized and Intact Dogs (Frontiers) “Behavioural risks in male dogs with minimal lifetime exposure to gonadal hormones…” (PLOS ONE) – Analysis of over 6,000 male dogs suggests lifetime exposure to gonadal hormones influences many behaviours including fear and aggression, with varied differences between entire and castrated males. Behavioural risks in male dogs with minimal lifetime exposure (PLOS ONE) “Behavioural risks in female dogs with minimal lifetime exposure to gonadal hormones” (PMC) – This study reports that female dogs with shorter exposure to gonadal hormones were more likely to show some fearful and aggressive behaviours than intact females. Behavioural risks in female dogs with minimal lifetime exposure (PMC) “Behavioural effects of neutering before vs after puberty” (PubMed/related research) – Prospective data in Labradors/Goldens show little to no difference in behaviour when bitches are neutered before or after puberty, including aggression. Behavioural effects of neutering before vs after puberty (PubMed) Literature review on neutering behaviour effects (Cambridge Core / related reviews) – A review indicates evidence is mixed and incomplete on how neutering and the timing of gonadectomy affect behaviour, with some studies showing hormone exposure may influence certain undesired behaviours.
