Spaying and neutering.
Denver Revised Municipal Code § 8-55
in effectSec. 8-55. - Spaying and neutering.
(a) It shall be unlawful to own or keep in the city any dog or cat over the age of six (6) months that has not been spayed or neutered except as provided in section 8-56.
(b) It is the purpose of this section to promote the health, safety, and general welfare of the residents of the city by reducing the number of stray dogs and cats. The council finds that each year tens of thousands of dogs and cats are euthanized in the city because they are not wanted. It is the purpose of this section to eliminate the excessive number of unwanted animals and thereby stop the needless killing of these animals by restricting the breeding practices of pet owners and breeders through legislation that is both reasonable and enforceable.
