As a caregiver, it’s essential to understand what your furry friend perceives in their daily life, that may be invisible to you. This piece will take you on a journey through a dog’s eyes, revealing five key aspects that dogs can see, which we humans can’t.
1. Ultraviolet Light
Dogs can see ultraviolet light, a spectrum of light invisible to humans. While we may only see a bright sunny sky, your dog can perceive the glowing trails left by animals or the sparkling urine markings on grass.
- How does it work? Canine eyes have more light-sensitive cells, or rods, and a special layer behind the retina called the tapetum lucidum, which enhances their night vision and ability to see UV light.
- Why does it matter? This ability helps dogs track and hunt, even in low light conditions.
2. Heat Waves
Yes, your dog can literally see thermal radiation, or heat. This ability is more common in predatory animals, but research suggests that dogs may also possess this skill.
- How does it work? Dogs have a heat-sensing organ called the vomeronasal organ located in their noses, aiding them in detecting thermal radiation.
- Why does it matter? This skill enhances a dog’s ability to sense danger or find prey.
3. The World in Blues and Yellows
Unlike humans who see the world in a variety of colors, dogs see the world in shades of blues and yellows. They are colorblind compared to humans, but they still perceive some colors.
| Humans See | Dogs See |
|---|---|
| Red | Dark Gray |
| Green | Light Yellow |
| Blue | Dark Blue |
4. Rapid Movements
Dogs have a higher flicker fusion frequency than humans, meaning that they can spot rapid movements better than we can. This is why your dog might suddenly get excited about a fluttering butterfly or a running squirrel that you may not even notice.
5. Emotional Changes
Your dog is an empathetic creature. They can “see” or sense your emotional changes. They can pick up on subtle changes in your body language, tone of voice, and overall behavior.
- How does it work? Dogs are extremely observant and can quickly pick up on the slightest changes in their human’s behavior.
- Why does it matter? This ability allows dogs to comfort their humans when they are upset or anxious.
