The behavior of stray dogs actively approaching and rubbing against people is usually a friendly gesture towards humans and an expression of seeking attention. This behavior may be due to a variety of reasons, including a desire for food, warmth, security, or a search for closeness and social interaction.

1. The background and experience of stray dogs may have an impact on their behavior of actively approaching and rubbing against people. Many stray dogs may have been domestic pets but left their homes for various reasons, leading to a wandering lifestyle. These stray dogs may have received love and care from humans, so they have a certain degree of trust and dependence on humans. Therefore, they may actively approach and rub against people in the hope of seeking similar care and concern.

2. Stray dogs may satisfy some basic needs by actively approaching and rubbing against people. For example, they may approach humans in search of food or water. In urban environments, humans often carry food, and stray dogs may learn to approach humans for food opportunities. In addition, stray dogs often do not have permanent homes, so during cold weather, they may rub against people to get some warmth. Human body temperature makes them feel comfortable and safe.

3. Dogs are social animals and they need social interaction and companionship. Stray dogs may feel lonely due to lack of family or companions and seek socialization by actively approaching and rubbing against people. Stray dogs want human attention and affection, which can also be seen as a sign of their friendliness towards humans.

4. Stray dogs may show stronger affinity toward certain humans, which may be related to their experience and individual personality. Some stray dogs may be more inclined to form close relationships with humans, and they may approach and rub against people more actively. However, some stray dogs may keep their distance from humans due to past experiences of harm or fear.

Understanding the background and experiences of stray dogs, as well as the personality traits of each individual, can help to better understand their behavior.
