Why we love them

The dog is one of the most loved animals in the whole world. Dogs come in hundreds of shapes and sizes, from tiny ones that could sit in your lap to big, tall ones as heavy as a grown-up. Whatever they look like, all dogs belong to the same family.

Long, long ago, dogs came from wild wolves. Over thousands of years, people and dogs became friends, and dogs were the very first animal we ever kept close. That is why dogs are so good at understanding people, reading our faces, and learning what we say.

A dog's best sense is its nose. Dogs can smell things far too faint for us to notice, so they explore the world by sniffing. That amazing nose helps some dogs find lost people, sniff out treats, or follow a trail across a field.

Dogs eat lots of different foods. They enjoy meat, but they can also eat grains and vegetables, which is why we call them omnivores. A bowl of good dog food and plenty of fresh water keeps a dog happy and healthy.

Baby dogs are called puppies, and a group of puppies born at the same time is a litter. A mother dog feeds her puppies milk and keeps them warm, licking them clean and guarding them until they are big enough to play and explore on their own.

Because dogs live with people all over the world, there are more dogs than ever. They help us in many ways, as farm helpers, guide dogs, and gentle friends, and in return we give them food, walks, and a cosy place to sleep.

Dogs were the very first animal that people made friends with, thousands of years ago, long before farms even existed.

A dog's sense of smell is far stronger than ours, which is why dogs love to sniff everything they meet.

Baby dogs are called puppies, and a whole group of puppies born together is called a litter.

Every dog can feel happy, scared and loved — just like you.

Looking after my friends

How many are there?

At least 700 million dogs were estimated worldwide in 2022.

WOAH reports a lower bound rather than an exact total. It includes owned, community and unowned dogs, and countries do not all count those groups in the same way.

How are they doing?

No global assessment

This animal does not have a global extinction-risk assessment recorded in this system.

Official status: not evaluated (IUCN)

You can help by learning what good care looks like, treating animals gently, and supporting people who protect their wellbeing.
