According to Coppinger & Coppinger (2002), the dog is a domesticated species that evolved from the wolf. Domestication is the process of hereditary reorganization of wild animals into domestic forms according to people's interests. This process began about 12,000 to 15,000 years ago when dogs emerged from wolves. However, dog domestication only established itself in the early Neolithic era when agricultural communities were established.

The process of domestication is responsible for the behavioral, physiological, and anatomical changes that occur in animals. Coppinger & Coppinger (2002) state that dogs are social animals and do not have the group structure of wolves. Although they can cooperate, they do not work together to ensure the survival of the group. Therefore, it is important to understand that a dog is a dog and will have specific behaviors and needs, regardless of breed.

When choosing a dog breed for the family, it is essential to take into account the purpose for which it was created and the typical behavior of each breed. For example, a family with two young children and a busy routine may have problems dealing with dog breeds that are very energetic and require a lot of exercise and mental stimulation. In these cases, it is recommended to choose calmer and more independent breeds that can adapt better to the family's routine.

In addition, it is important to keep in mind that each dog is unique and may have its own personality and individual needs. Therefore, it is essential to dedicate time and attention to training your dog and seek the help of a professional trainer if necessary.

In general, choosing a dog for the family is a decision that should be made with care and information. Understanding the origin and evolution of dogs, choosing a breed that suits the family's lifestyle, and dedicating time to training and socializing the animal are essential to ensure that it becomes a beloved and valuable member of the household for many years.

Currently, there are many different types of dogs, each with its own innate characteristics and abilities. Some were bred for herding, others for hunting, and others for companionship. In this article, we will analyze three different dog breeds and discuss whether they are still suitable for their original purposes, the difficulties that may arise in a busy domestic environment, and how to stimulate and reinforce acceptable behaviors.

Starting with the Belgian Malinois breed, we can see that it is a herding dog, originally bred to herd sheep. As such, it is still perfectly suited for this purpose. However, these dogs are very versatile and excel in many other areas. They are often used as police dogs for protection, in military activities such as scent detection, and in humanitarian crisis scenarios, searching for and rescuing people. Malinois dogs are considered very hardworking and excellent guard dogs.

However, there may be problems with these dogs in busy domestic environments, especially with young children. As herding dogs, they have a strong instinct to chase and may sometimes even bite. It is important that they are socialized and trained properly to avoid dangerous situations. Interactive games that stimulate their natural behaviors can be useful to channel their energy, but it is crucial that they are taught to play in an educated manner.

The Cavalier King Charles Spaniel breed is a companion dog, bred to be a loyal friend. They are suitable for domestic environments, especially for families that do not have much space or time for prolonged outdoor activities.

However, these dogs do not handle loneliness well and may have training problems to do their business in the right place. It is important that they are supervised around small children and other pets, as they still have a hunting instinct.

If you are thinking of having a Border Terrier as a pet, it is important to know that these dogs were originally bred to hunt and kill foxes. Although they can still be used for sport hunting, they are not ideal for a busy domestic environment. They have a strong instinct to dig and hunt, which can lead to problems with neighbors and other pets. They also need a lot of mental and physical stimulation to avoid destructive and escape behaviors.
