Dogs can see color, but only in shades of blue and yellow. Because dogs can only see two colors, they have dichromatic vision. They can also see shades of gray. Colors such as red, orange, and green are out of a dog's color spectrum, so these colors are not visible to dogs.
Dogs are red-green color blind. They see a brighter and less detailed world when compared to humans. Peripheral vision is better than humans (dogs see more of the world), but distance is not judged quite as well. Dogs excel at night vision and the detection of moving objects.
Dogs can see distant movements more easily than humans can, but they cannot distinguish the same level of detail. They are also not able to see colors quite like we do; instead they have a broader range of shades that our eyes don't detect.
Contrary to popular belief, dogs do not have perfect vision. In fact, they may struggle to focus on objects in great detail, perceiving the world as slightly blurry.
For dogs, their color vision is most similar to a human with red-green color blindness, although there are other differences. Dogs are less sensitive to variations in gray shades than humans are, as well as only about half as sensitive to changes in brightness. Dogs also tend to be nearsighted to varying degrees.
That said, most researchers believe dogs can remember important people and significant events in their lives for years, perhaps until death. So, yes, your dog remembers your scent, your face (especially your eyes), and your voice and associates them with happiness, love or snuggling, or maybe just with food.

Although dogs can't identify themselves in the mirror, they still have some level of self-awareness and ace other self-recognition tests. They can recognize their own odor, and recall memories of specific events, Earth.com reports.
Some experts believe that dogs know we are a different species, so they wouldn't consider us eligible for their furry four-legged group. That said, dogs often treat us as like we're part of one big happy pack. They can be incredibly loyal and loving to their family members.
Dogs have rod-dominated retinas that allow them to see well in the dark. Along with superior night vision, dogs have better motion visibility than humans have. However, because their retinas' contain only about one-tenth the concentration of cones (that humans have), dogs do not see colors as humans do.
Overall, dogs are complex creatures that think about a wide range of things, including social relationships, their physical environment, daily routine, physical needs, and health and well-being.
In dogs, however, brain activity remained the same when shown either picture. This is because dogs do not have specialized areas in the brain to process faces like we do. In other words, humans have a face-sensitive region in their brain, causing us to respond differently when seeing another face, whereas dogs do not.
Obviously, his stronger sense of smell is useful, but it's also because dogs can see movement and light in the dark, and other low-light situations, better than humans. They are assisted by the high number of light-sensitive rods within the retina of their eyes. Rods collect dim light, supporting better night vision.
“Dogs use eye contact as reassurance and understanding in very similar ways that humans do, to ascertain interpersonal connection and reaction. This helps us connect with them as well,” he says.
They've learnt to look at human faces for communication clues and can even tell how we're are feeling by how we look!

Studies have shownthat dogs process language in a similar way that humans do, using both sides of their brain to understand body language, tone of voice, and context clues. With this method, dogs can learn many different words, including their own name and various nicknames.
“Dogs identify things and people by their unique scent, much more than visual and audio cues, so while they may hear a familiar voice on a phone call or video, without the scent to accompany it, it just kind of confuses them and they quickly lose interest.” Even though Finn has the best ears in the house — he can hear ...
Dogs are good at reading us, and they usually know when we are being affectionate, such as when we kiss them. Because they love affection from us, most dogs do like being kissed. However, they don't like the act of being kissed but rather that we give them attention and show affection.
THEY CONSIDER YOU A PACK MEMBER.

This calming sensation triggers a specific reaction in their brain that responds to hair follicle stimulation. Dogs, like humans, also release endorphins and oxytocin through methods of touch, so rubbing a dog's belly can help with bonding and affection. Ultimately, dogs like belly rubs because they feel good!
When dogs sniff people they are gaining all sorts of information about us. They know if we are familiar or a stranger. They know which scents we have attracted while we've been away. They know if we are experiencing changes in hormones, such as those that occur during pregnancy.
The three most common reasons for a dog yawning are regulation of stress levels, out of trust or mimicking our behavior, or tiredness and boredom—just like us pet parents. To figure out the exact reason, you'll need to decipher their behavior and look at context clues.
