The behavioural effects of castrating male dogs (Neutering)

Having your dog neutered is not a decision that you should take lightly, after all there is no going back once the deed is done! Before proceeding you should consider the effects that castration may have on your dog’s behaviour.

The castration of male dogs will stop the production of the hormone testosterone. This might be beneficial when treating unwanted behaviours that are more likely in males than in females. Urine marking, roaming away from home to track down bitches in heat, inappropriate sexual behaviour, and inter-male competitive behaviour. In contrast, and contrary to popular belief, castration does not “calm a dog down”, since excitable and unruly behaviours are seldom influenced by testosterone.
