If you have ever fed or played with a stray dog, you may have wondered if they remember you after you go. The answer is yes, dogs do remember people who are kind to them.
A study was conducted in 2012 that showed that dogs have the ability to recognize and remember human faces. In the study, dogs were shown pictures of their owners and strangers. The dogs looked longer at the picture of their owner than the stranger's face. This showed that they could tell the difference between familiar and unfamiliar faces.
Dogs also use other cues, such as smells and sounds, to recognize people. So if you have ever fed a stray dog, they will most likely remember you by your scent. They may even come looking for you if they see you again because they know you are a source of food.
If you have been kind to a stray dog, they will definitely remember you and appreciate your act of kindness!
