One of the main reasons to ask you something is that your dog looks at you to ask for what they need or if your dog looks at you very carefully they may want to go for a walk when you get back home.  If they haven't eaten in a while they may be trying to remind you that dinner time is approaching they may want attention or love so they can see you by then.  This often happens when we are busy doing other things until you pick them up. Although this behavior is common in dogs, we may inadvertently reinforce it if we offer them a toy.  Or every time they look at us they can encourage this action as a reward.  Encourage them to do this in the future as they read your expressions Dogs often use body language to communicate with their guardians as well as other animals in their environment, partly because  They pay so much attention to our behavior. By paying attention to these facial expressions and gestures they can understand our state of mind and intentions. This is why your dog often reads and understands your feelings.  Looks at you What you are trying to express non-verbally This happens especially when we talk to our dogs or do something that makes them feel curious or weird  We can keep our eyes open because we are working out of the ordinary. Even though what we do does not seem unusual, we need to be careful with our body language if you want to improve.
