Domestic Dog

Humanity's oldest companion — the familiar friend waiting at every park gate and pavement corner.

Least Concern

Domestic Dog

Overview

The domestic dog was the first animal humans ever tamed — a partnership stretching back more than 15,000 years. From tiny terriers to towering mastiffs, dogs have been shaped by every culture on Earth into hunters, herders, guards, and friends.

For Catch'Um collectors, the domestic dog is often the very first log: a wagging tail on a morning walk, a patient face at a café table, or a bounding figure across a field. Common, yes — but a genuine discovery that connects the game to real life from day one.

Habitat

Domestic dogs live alongside humans in every environment we inhabit — cities, suburbs, farmland, and mountain villages worldwide. They are found in parks and neighbourhoods, on beaches and hiking trails, wherever people gather and keep them as companions or working animals.
