Dogs see color, but not as vividly as humans; they have dichromatic vision, seeing mostly in shades of blue and yellow, while reds and greens appear as brownish or grayish tones. This is because dogs have two types of color-detecting cone cells (blue and yellow sensitive) compared to humans' three (red, green, and blue sensitive). Their vision excels in low light and motion detection due to more rod cells, but they rely heavily on scent, making their world a less colorful but motion-rich place.
Because dogs' eyes only have two types of cones (just 20 percent of the cones in human eyes), their color spectrum is limited to shades of gray, brown, yellow and blue.
An hour for a dog feels much longer than an hour for a human because dogs perceive time more slowly due to their faster metabolism and heightened awareness of routines, so a 10-minute wait can feel like 70 minutes to them, and your hour-long absence feels like an eternity, though they don't grasp clock time but rather the intervals between events like meals, walks, and your return.
Since dogs' eyes have blue and yellow cones, your dog can't distinguish red or green. This means he can't perceive colors like orange, pink or purple. Dogs see shades of blue, yellow and gray best.
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. Dogs see like a color-blind human.
To say "I love you" in dog language, use soft eye contact, raise your eyebrows, give gentle massages (especially ears), lean into them, and engage in play or shared activities like walks, which build trust and affection through shared experiences and physical connection, releasing oxytocin for both of you.
While they can still navigate their surroundings better than humans in total darkness using their other senses, they will not be able to see. While it's rare for them to be in complete darkness, it's helpful to leave a nightlight on so your dog can see better at night.
To a dog, grass isn't bright green like it is to us; it appears as shades of yellow, brown, or tan, similar to how humans with red-green color blindness see it, because their vision is dichromatic, focusing on blues and yellows. A red ball on green grass might look like two different shades of brown or tan to your dog, but blue or yellow toys stand out well against the muted background.
Dog eyes are very different from human eyes, so they see things on TV differently. Their vision isn't as sharp, being closer to 20/75 than 20/20, which may explain why they prefer to sit closer to the TV than we do—it helps keep the images sharp.
Studies have shown that dogs are more attracted to blue and yellow toys than any other colour. This is likely because these colours stand out the most due to their dichromatic vision.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
How do they do this? It's biological. All animals have circadian rhythms - physical, mental, and behavioral changes that follow a 24-hour cycle, responding to light and darkness in the environment. They may also be affected by factors like temperature and social cues.
Harvard psyhologists reveal that dogs dream of their humans
What you may not have realised however is, according to new research by Harvard psychologists, your dog is likely to be dreaming about you too – their human – the most important thing in their life.
Dogs do the same thing. They tilt their heads to work around their interfering muzzles and improve their visual perspective. That cute head tilt broadens the range of vision and allows a dog to more clearly see a person's face. Seeing our facial expressions improves communication.
Dogs see the colors blue and yellow best. Their vision is dichromatic, meaning two-colored. In addition to seeing blue and yellow, dogs can also see the full spectrum of greys. Dogs see the color red the worst, they cannot see colors made of red either, like orange and purple.
While dogs interact with humans in ways similar to how they engage with other dogs, research suggests they do recognize that we are different. However, instead of seeing us as a completely separate species, dogs categorize us into their social structure as if we were just another (very odd) member of their pack.
Dogs say "sorry" through submissive body language like tucking their tail, lowering their head, making "puppy eyes," licking, and rolling onto their backs to show they're not a threat, which are appeasement signals to diffuse tension after a conflict or misbehavior, often combined with whining or approaching and retreating. They recognize when their human (or another dog) is upset and use these signs to seek forgiveness, though it's more about reducing stress than human-like guilt.
If they rely most heavily on their sense of smell, it might not matter whether the TV is on or not. However, if they use their hearing prominently, the ambient noise of the television can keep them from being anxious, when left home alone.

Given their visual limitations, dogs are naturally more attracted to blue and yellow. These colors stand out more in their environment, making objects of these colors easier for them to notice and interact with.
While we can't ask dogs to read an eye chart or pick out colours, behavioural tests suggest that dogs see in shades of yellow and blue and lack the ability to see the range of colours from green to red. In other words, dogs see the colours of the world as basically yellow, blue, and grey.

Generally, dogs dislike hugs, not being allowed to sniff, a lack of routine, and more. Even the most laid-back dog will hate some of the things we humans do—if they tolerate it, it's just because they love you or don't want to be dominant.
In conclusion, dogs are sensitive creatures that can remember and react to raised voices. While they don't hold grudges, repeated negative experiences can impact their behavior and emotional well-being. Understanding your dog's emotional states and body language is crucial for building a strong and loving relationship.
