Dogs and humans see the world in different ways. Humans are farsighted and see best at long distances, while dogs are nearsighted with acute senses of sight, smell, and hearing. So what can dogs see that humans can’t? Quite a bit, it turns out. Dogs have an amazing ability to see things that humans either can’t or detect much less acutely. If you have a dog, you know they’re more than just a cute face — it’s a friend who adds more meaning to your life every day. The special relationship you have with your dog is one-of-a-kind…but what makes it so unique? It’s probably because dogs and humans see the world so differently!
What Can Dogs See That Humans Can’t?
Dogs have very different visual systems than humans. Their eyes have a retina containing two types of light receptors: rods, which are good in dim light, and cones, which are not as sensitive to dim light but which provide color vision. Humans only have cones, so we see color in bright light but we don’t see much detail in dim light. Dogs can see color even in the dark!
The Meaning Of Doggie Vision
- Dogs have a wider field of vision than humans and can see at approximately 220 degrees compared to humans at 180 degrees. They also have a greater depth of field, which allows them to perceive things at a farther distance than humans. Dogs’ eyes also have a greater sensitivity to light than ours, which makes sense since they’re out and about during the day when it’s bright out. They have larger pupils and non-clickable eyelids, so they have to find creative ways to keep their eyes closed when they want to rest.
- Dogs have more rods than humans, which are the type of cells in their eyes that detect light. Rods allow dogs to see at night, and dogs have about 20 times more rods than humans do. Humans tend to rely more on cones, which allow for color vision. Dogs’ eyes also have a reflective layer behind the retina, called the tapetum lucidum (the “bright carpet”), that allows them to see better in low light situations by reflecting back any available light that hits the retina.
- Dogs’ sense of smell is around 1000 times stronger than human’s sense of smell. They can pick up scents in concentrations that are one part per trillion, while we can only detect something if it has one part per million concentrations present! Their noses are so sensitive that they can even smell things buried under the ground or underwater!
- Dogs only have two kinds of cones: blue and yellow. That’s it! Humans, on the other hand, have three different kinds of cones: blue, green, and red. We also have rods for detecting light, which dogs don’t have. Dogs’ eyes aren’t very sensitive to color like ours are. They can see some colors, but it’s not their main way of perceiving their environment like it is for us humans.
- Dogs see in black and white and shades of gray, while we see in color. Dogs also tend to respond better to high-contrast images than humans do because they can see better at night when there isn’t much light around! Dogs don’t really notice reds or greens that well, but they do seem to be attracted to yellow and blue things (like toys).
- Dogs are more nearsighted than humans are; they need glasses! They also have a larger blind spot and fewer photoreceptors (rods and cones) in the retina of their eyes.
- Dogs don’t have a fovea, which is a spot on the retina that contains the most photoreceptors and is responsible for allowing us to see details in what we’re looking at. Dogs also don’t have as many neurons that connect to the visual cortex of their brains, so they are not as good at perceiving moving objects as humans are.
- Dogs can detect up to 10 times more odors than we can! Their nose is covered with scent receptors called olfactory epithelium, which detects smells and sends signals directly to the brain. We, humans, have about 5 million smell receptors; dogs have about 220 million!
- Dogs have a special part of their brain called the amygdala, which is responsible for processing information about smells. They also have a part of their brain called the piriform cortex, which processes smells and sends signals to the amygdala. Our brains don’t have these parts, so we can’t smell as well as dogs do!
- By smelling urine from other dogs, dogs can tell who you are and where you live! They can also tell if you are female or male, old or young, and even what your mood is! We humans don’t have this ability.
- Dogs have an extra olfactory organ called the vomeronasal organ (VNO), which sends signals directly to their limbic system (emotional center). This is located right behind our nose and above our upper lip! It doesn’t seem to be present in humans at all; we don’t use it for anything
For Selling People And Things
- Honesty is the best policy when it comes to your relationship, and this is especially important when you are first dating. You don’t ever have to lie to your partner, and you don’t have to tell them everything, but you should never be dishonest. If you are looking at other people or considering ending the relationship, be honest with your partner, but do not tell them everything to protect their feelings.
- When it comes to selling people and things, you should never try to oversell, but you should always be honest about what you are selling. If you are selling something that is not very desirable, be honest about the fact that people will not want it. For example, if you sell a car that is old and in need of repair or one that needs a lot of work done on it, tell them how much work the car needs before they purchase it.
- It is important not to lie when trying to sell someone something because this will make them suspicious of your motives and whether or not they want to buy the product or service that you are offering them. If someone asks a question that makes them think twice about buying your product or service, be honest with them and tell them why they should buy from you instead of another company.
- When talking about the price of your product or service, try your best not to give away all of the information. If you give away too much information, they will know that they are getting a good deal, and they will not be willing to pay as much as you are asking for the product or service that you are offering them.
- When trying to sell something to someone, try your best not to offend them by telling them what kind of person they are or how old they look before you tell them how much your product is worth. If you do this, it could ruin any chance that you have of selling the product or service that you have in mind for them.
- When selling someone an item, never try to sell them something that is more expensive than what it actually costs because this could make the person who bought it feel as though he was misled into buying more than he wanted to pay for it.
- When trying to sell people products and services, don’t give away all of the information about your product or service. If you do this, they will know that they are getting a good deal and they will not be willing to pay as much as you are asking for the product or service that you are offering them.

Conclusion
Dogs see colors, have super-hearing, and can even see things in the dark better than humans can! Plus, dogs have an acute sense of smell and can detect many environmental pollutants. If you’re ever wondering what your dog sees when he looks at the world, know that it’s a lot more than you can see! Humans and dogs have a special relationship because we see the world so differently!
