It's not still relevant because a baby and a dog are not equivalent. A baby has rights a dog doesn't. A baby might disturb people, so might an adult, but both are humans and you have to take the risk of being disturbed by humans because society is made of humans. Society is not made of or for dogs.

It is utterly insane to expect anyone to spend a cross-country flight with an 80lb Labrador next to them slobbering all over them.
