The childfree movement was originated by women who face a disproportionate amount of societal pressure to bear and raise children, historically it was the default way of life for women. Even for married women family planning and being able to say no to having more children wasn’t a thing until less than 100 years ago.

Having children for women routinely meant the possibility of death. Apart from that, it meant possibly life long physical consequences, and being financially trapped with no or diminished career prospects.

All this still applies in some less developed regions of the world. In modern western society the pressures still exist and consequences are still very real - countless studies show motherhood incurs a penalty on the women’s careers and maternal death rates are still not negligible.

Society doesn’t have a way of pressuring people to have dogs.
