Dogs tilt their heads for various reasons, including:
1. *Communication*: To convey interest, curiosity, or confusion.
2. *Listening*: To better hear and locate sounds.
3. *Visual processing*: To see things from a different perspective or to focus on specific visual cues.
4. *Social signaling*: To show empathy, understanding, or connection with their human companions.
5. *Cognitive processing*: To process and understand complex information, like trying to understand human language.
6. *Playfulness*: To initiate play or show excitement.
7. *Attention-seeking*: To get a reaction or interaction from their human.
Remember, each dog is unique, and the reasons for head-tilting can vary depending on the individual dog and the context.
