Castration of dogs is a widespread practise with clear justification in
population control and knock-on benefits for animal welfare. Deleterious
behavioural consequences of castration are believed to be negligible. Gonadectomy
is widely recommended as part of a multi-factorial approach to prevent problems
including aggression in dogs. However, the consequences of early castration on
health are still being debated. The current study focused on the reported
behaviour of 6,235 male dogs castrated before 520 weeks of life for reasons other
than behavioural management, and calculated their percentage lifetime exposure to
gonadal hormones (PLGH) as a proportion of their age at the time of being
reported to the online Canine Behavioral Assessment and Research Questionnaire
(C-BARQ). Forty behaviors differed between entire and castrated dogs, of which 25
were associated with PLGH and 14 with age-at-castration (AAC). Only 2 behaviours,
indoor urine marking and howling when left alone, were significantly more likely
in dogs with longer PLGH. In contrast, longer PLGH was associated with
significantly reduced reporting of 26 (mostly unwelcome) behaviours. Of these, 8
related to fearfulness and 7 to aggression. The current data suggest that dogs'
tendency to show numerous behaviours can be influenced by the timing of
castration. They indicate how dog behaviour matures when gonadal hormones are
allowed to have their effect. The differences reported here between undesirable
behaviours of castrated and intact dogs were in the range of 5.04% and 12.31%,
suggesting that, for some dogs, partial or complete denial of puberty may reduce
indoor urine-marking but have many other undesirable consequences. Veterinarians
may use these data to discuss unwelcome consequences with owners of male dogs
before castration.
