Staring and Different Types of Eye Contact
Dogs express themselves in many different ways. For example, when they are staring at you, it probably just means they are craving attention. However, if they are staring at you while their tongue is sticking out, that could mean that they are demanding your attention but are content with how things are going.
If your dog is staring at you intensely, it means that they are attempting to decipher what your behavior means.
