The vast majority – around 90% – of registered dogs in Australia are desexed. It is believed, however, that a large percentage of unregistered pets in this country have not been desexed.
In Australia, the desexing of dogs plays a large role in the animal birth control strategy, and helps keep the number of accidental litters and unwanted dogs low.
In North America, desexing is very popular too whilst in Europe the number of desexed dogs is much lower in comparison.
Dog desexing is not mandatory in Australia, however, rescue organisations and shelters will generally desex animals before they go into new homes.
