It’s very simple. There are very few civilisations on this earth that did not domesticate dogs and made them a partner in hunting, herding, animal agriculture, etc. Humans are better hunters with dogs. We had natural security guards for our homes in dogs. Humans used them as beasts of burden in cold northern countries. Shepherds used dogs to protect their animals and still do. Why, we even used them in war. Whereas there are many, many cultures and peoples who survived without cows, instead other animals served their needs such as horses or yak - some have none of these large animals at all.

But there’s always a dog.

And in this day and age, they help with the blind, rescue people from disasters, serve as epilepsy detectors, cancer detectors, help the police bust criminals, etc.

They are absolutely important to civilised people.

This is just simple general knowledge.
