The world of dog breeds is vast, and extremely interesting. When you understand the different dog breeds and how they came to be, you can better understand the type of dog you'd like to bring into your home.
Additionally, the history of dog breeds sheds light on how important and incredible dogs are. Dogs have helped human beings advance in many essential ways, and it's very possible that human civilization would be less advanced if we had never domesticated dogs.
Keep reading to get a deeper understanding of the different classes of dog breeds, where they're from, ways to support their health, and how they came to be.
From Wolves to Family Members: Breed Origins
Before there were specific dog breeds, there were wolves. The leading theory is that 15,000-30,000 years ago, wolves domesticated themselves by following human groups and scavenging. This process played out multiple times, in different continents, which is part of the reason there are so many breeds today.
The friendlier, tamer scavenging wolves were welcomed by humans and rewarded with more food, security, and comfortable by their chosen humans. In return, wolves offered human groups security by alerting us to threats, hunting for food, and cleaning up food waste that could draw predators.
Generation after generation, wolves were bred by humans to be less wild and more domesticated. Traits like aggression toward humans were left behind, and positive qualities like hunting ability and intelligence were honed.
Breed Diversification & Advances to Humankind
Once wolves engrained themselves into our lives, they became evolutionary partners for us. Their contributions to human societies, in some measure, allowed us to make advancements that define the evolution of our species. These contributions dictated the way breeds would diversify and result in the tapestry of wonderful dogs that exist today.
Here are a few key contributions that dogs made to humanity:
- Awareness of Predators: Dogs' ability to keep watch and spot predators allowed human groups to sleep safely, and even form larger groups that could remain stationary rather than wandering.
-
Hunting & Tracking: The ability to track and hunt animals allowed humans to be more efficient while hunting, increasing food supplies and reducing the resources needed bring food back to the camp.
- Template for Domestication: The domestication of dogs served as a guide for how to domesticate other animals, allowing humans to farm and raise livestock, reducing the need to migrate. This is a massive factor in the birth of human cities and, ultimately, civilizations.
- Herding & Protection of Livestock and Grain: Herding livestock would be impossible without significant manpower without the help of dogs. One dog can herd a flock of sheep or cattle more effectively than many human beings. Additionally, hunting vermin that could ruin crops or crop stores allowed humans to stockpile food and live well with a lower risk of disease.
These specialties would set the stage for all dog breeds to diversify and be extremely effective companions to this day. Let's look into each of the categories of modern dog breeds.
The 7 Primary Modern Dog Breed Groups
The American Kennel Club distinguishes seven primary modern groups of dog breeds. These groups are set by the breed's function, energy, instinct, and behavior.
