Why Do Dogs Tilt Their Heads?

The video explores why dogs tilt their heads, presenting several hypotheses. Stanley Corin suggests it helps dogs see facial expressions better, especially for breeds with larger muzzles. A survey showed a significant difference in head tilting between dogs with different muzzle sizes. Alexandra Horowitz proposes that dogs tilt their heads to hear better, while Steven Lindsay believes it involves brain regions controlling both listening and body language. Despite these theories, the exact reason remains unclear, and further research is encouraged.
