The reason is because of glacial desposits. The other reason is because of ice bergs and continental drift.
Continental drift :)
The force responsible for the movement of continents is called plate tectonics. The Earth's outer shell is divided into large plates that float on the semi-fluid asthenosphere below. These plates move due to the heat-driven convection currents in the mantle, causing the continents to drift over millions of years.

There is no city present in all continents. Each continent has its own distinct cities.
Through the passage of time, the continents have gradually moved across the earth's surface into their present positions. This is called the continental drift.
The hypothesis that states continents slowly moved to their present positions on Earth is known as the theory of plate tectonics. It suggests that Earth's lithosphere is divided into several large, rigid plates that move and interact with each other over time. These movements explain various geological phenomena, such as earthquakes, volcanoes, and mountain formation.

Dogs are pets bread by Man and therefore dogs are present on all continents.
Continents and tectonic plates drifted to their present positions due to the process of plate tectonics. This movement is driven by the slow shifting of the Earth's lithosphere on the more fluid asthenosphere beneath it. The movement of these plates over millions of years has resulted in the present configuration of the continents and ocean basins.
It has taken around 200 million years for continents to get to their present positions due to the process of plate tectonics, where large pieces of the Earth's lithosphere move slowly over the underlying mantle. This movement results in the shifting of continents and the formation of various landforms on Earth.
