[20] [21] [22] GonaCon has been studied in male and female dogs and cats but does not provide long-acting suppression of fertility in these species. In dogs in particular, injection site reactions preclude use of the EPA approved formulation. [23] [24] Zona pellucida vaccines are targeted at females and do not suppress fertility in dogs or cats ...
