Types of Domestic Dogs
There are many varieties of dog breeds, but they all have one thing in common: dogs want to please their owners. A dog will do whatever it takes to entertain its owner. This is why dog breeds come in so many different varieties. The size, the activity level, and the interests of each breed of dog are almost limitless. Even between breeds, there are subtle differences. Some breeds are smaller, stronger, or more compact than the others.
The dog originated from an ancient, now extinct wolf family, the sighthounds, and the earliest known dog was an ancestor of the domestic dog or wolf. Over time, dogs changed quite a bit, becoming more like people. Modern day dogs are more compact, stronger, and faster than ever before. The genetic blueprint of dogs includes a gene that makes dogs more compatible with people, making it easier for dogs to interact with humans.
There is no way to know exactly when dogs evolved from wolves, but the theory of evolution by natural selection makes sense. The most likely scenario for dog domestication is that dogs branched off from a group of wolves, who were highly social and survived by hunting small prey. Over time, the social network was replaced by the family unit, and dogs became more individualistic and dominant. One of the most obvious signs of domestication is the separation of the house and the yard, which were reinforced by scent marking their territory. The need for territory became less important as human activities became more alike.
Most domestic dogs today live in small apartments, so the idea of a good, strong, and loyal companion is not very appealing to most dog owners. Because of this, many breeds developed characteristics such as muscular power, endurance, and reliability. In fact, all dogs are descendants of wolves, but the different lines of wolves vary widely in how they behave and how they act toward their fellow wolves. Some dogs have an extremely submissive personality, while other dogs are aggressive and hostile.
Dominant, submissive, or friendly breeds tend to have a better chance of being adopted by families. While there are many different temperaments in domestic dogs, the general idea is that a dog with one dominant trait is generally considered bad, while a dog with several traits that are the polar opposites of dominant are considered good. In some cases, domestic dogs may display only one or two dominant traits. Mixed breeds are often categorized as domestic dogs, because they combine one dominant trait with another that is considered non-dominant.
Small dogs tend to be less aggressive than large dogs, but small dogs also have their own set of needs. Unlike large dogs, small dogs need constant attention and exercise, because they have a much lower metabolism and cannot move quickly and work independently. However, small dogs make great companions for children and old people, because they have a loving nature, are very affectionate, and do not shed much hair. While small dogs do not have a large amount of power in their muscles, they do have a strong, protective nature, because small dogs have a fear of bigger dogs. A small dog is also a more flexible pet and is typically used to perform delicate tasks, like pulling sleds, or working in farms.
