Castration of adult male dogs: effects on roaming, aggression, urine marking, and mounting

J Am Vet Med Assoc. 1976 Jun 15;168(12):1108-10.


In a retrospective study involving 42 dogs, it was concluded that the objectionable male behavioral patterns of roaming, fighting with other males, urine marking in the house, and mounting of other dogs or people are amenable to alteration by other castration in adulthood. Roaming was reduced in 90% of the dogs.
