How big were dogs in prehistoric times?

One of the most fascinating aspects of studying prehistoric times is looking at the evolution of animals, including our beloved pets – dogs. Dogs have been domesticated for thousands of years, but how big were they in prehistoric times?

When we talk about prehistoric dogs, we are usually referring to a specific breed known as the Dire Wolf (Canis dirus). This species of wolf lived in North and South America during the Pleistocene epoch, which lasted from about 2.6 million to 11,700 years ago. Dire Wolves were significantly larger than modern-day wolves, weighing up to 150 pounds and standing about 5 feet tall.

The evolution of dogs

While Dire Wolves were one of the largest species of prehistoric dogs, there were also smaller varieties. The evolution of dogs can be traced back to a common ancestor that lived over 30 million years ago. Over time, different breeds and species of dogs evolved, leading to the diverse range of sizes we see today.

Evidence of prehistoric dogs

There is a wealth of evidence to suggest the existence of prehistoric dogs. Fossils of ancient canids, such as the Dire Wolf, have been found in various parts of the world. Additionally, cave paintings and artifacts depict humans hunting with dogs, further supporting the idea that dogs have been domesticated for thousands of years.


Overall, prehistoric dogs came in a variety of sizes, with some species being significantly larger than modern-day dogs. The Dire Wolf is a prime example of a large prehistoric dog that roamed the Earth during the Pleistocene epoch. Studying the evolution of dogs gives us a glimpse into the rich history of our loyal companions.

According to a recent study, the average weight of a Dire Wolf was around 130 pounds.
