Dogs Have An Excellent Sense of Smell
We all know dogs have an amazing ability to sniff things out, but their sense of smell is actually tens of thousands times better than humans! The part of a dog’s brain devoted to analyzing smells is about 40 times larger than in people. Dogs also have up to 300 million scent receptors in their noses, while humans only have about 6 million.
This incredible sense of smell allows dogs to detect things we would never notice. Dogs can pick up scents that are diluted to 1 or 2 parts per trillion! Drug dogs are able to smell illegal substances, arson dogs sniff out accelerants, and many dogs can even detect health conditions like cancer or low blood sugar in their owners. Truly, a dog’s nose knows no bounds.
Dogs Only See In Black And White
Unlike humans who see in color, dogs see primarily in black, white, and shades of gray. This is because dogs only have two color receptive cone cells in their eyes, whereas humans have three. However, while dogs may not distinguish between red, green, and blue, they have many more rod cells which allows their night vision to be excellent.
Dogs also have a wide field of vision since their eyes are located on the sides of their heads. They see at an angle of 240 degrees compared to the 180 degree angle of humans. So while dogs may not see all the colors of the rainbow, they definitely have unique visual capabilities!
Dogs Have An Additional Eyelid
Dogs have a third eyelid called a nictitating membrane that is located in the inner corner of their eye. This membrane protects the eye from scratches and spreads tears across the cornea to keep it moist. Dogs can’t fully control when this third eyelid extends across the eye, but they can use it to remove debris or distribute tear film if needed.
Some dogs, like Chows and Shar Peis, appear to have an extra layer of skin covering the corners of their eyes. But really this is just an exaggerated version of the nictitating membrane. So if you notice a weird film covering your dog’s eye, there’s likely no cause for concern!
Dogs Sweat Through Their Paws
Humans sweat mainly through the pores in our skin to cool down. But dogs only have sweat glands on their paws and nose. When a dog is hot, its body will pump blood closer to the surface of their pads and nose which allows heat to dissipate. The evaporating sweat then has a cooling effect.
Since they can’t sweat all over their body, dogs will also pant to regulate their body temperature. The panting causes evaporation from the dog’s tongue and mouth instead. And of course dogs enjoy lounging around in the shade or splashing in water to beat the heat!
Dogs Have 18 Muscles In Their Ears
A dog’s ears are controlled by an impressive 18 different muscles. This allows them to rotate their ears independently, move them like radar dishes to pinpoint sounds, and communicate their mood.
Forward facing ears demonstrate that your dog is attentive, alert, and interested. Flattened ears signal the dog is feeling fearful or shy. Cocked ears indicate happiness or curiosity. One ear up and one ear down means your dog is feeling uncertain or conflicted. The many ear muscles give dogs an expressive form of nonverbal communication.
Dogs Curl Up To Conserve Heat
Why dogs curl up
Have you ever noticed your sleeping dog all curled up in a furry little ball? This adorable habit actually serves an important purpose! When dogs sleep with their limbs tucked in and bodies compact, it helps conserve body heat and regulate their temperature.
Other ways dogs regulate temperature
In addition to curling up their body, dogs also stick their nose under their tail or paws while sleeping. Their paws and nose get cold easily since they are not very insulated. So tucking these body parts into their fur helps dogs stay warm.
Dogs may also sleep back to back with other dogs to share body heat. And larger dogs tend to sprawl out since their greater mass retains more warmth. However they choose to snuggle up, these sleeping positions help dogs efficiently retain their precious body heat.
Dogs Have A Special Bond With Humans
Scientific research has confirmed what dog lovers already know – that dogs form extremely close bonds with humans. Here are some of the ways dogs show their special connection to people:
Oxytocin levels in dogs and humans
When owners interact with their dogs, both the human’s and the dog’s oxytocin levels – the hormone linked to bonding, empathy, and affection – go up. This rise in oxytocin strengthens the emotional bond between pets and owners.
Dogs can read human emotions
Dogs are able to recognize human facial expressions and cues. They can often tell when their owner is happy, sad, angry, or anxious. Dogs even mimic their owner’s stress through cortisol levels.
The ability to understand and empathize with human emotions is evidence of dogs’ highly advanced social intelligence. No wonder dogs are such an intuitive and comforting companion for so many people!
Dogs Chase Their Tails For A Reason
Tail chasing in dogs may seem like a silly behavior, but there are actually some logical reasons dogs spin in circles trying to catch their tail. Here are the most common causes:
Boredom
Dogs need activity and mental stimulation. If left alone for long periods, they can resort to chasing their tail just to have something to do. Making sure your dog gets adequate walks, playtime, and enrichment can help curb boredom.
Stress or anxiety
Dogs may chase their tail compulsively due to feeling stressed or anxious. Creating a calm environment and giving your dog outlets to expend nervous energy are some ways to help.
Medical issues
In rare cases, tail chasing could be caused by a neurological or gastrointestinal disorder. If your dog excessively chases their tail, consult with your vet.
So while tail chasing can look silly, it’s often due to an underlying issue that needs to be addressed. Pay attention to when and why your dog seems to chase their tail to get to the root of the behavior.
Puppies Are Born Deaf And Blind
When puppies are first born, their senses are not yet fully developed. Puppies are unable to hear or see during their first couple weeks of life.
When do puppies open their eyes and ears?
Puppies’ eyes remain closed during the first 7-14 days. Around 10-14 days their eyelids start to open and they gradually gain vision. Puppies’ ear canals open between 10-16 days, and their hearing starts improving shortly after. By the time puppies are 4-5 weeks old, their sight and hearing abilities are close to fully developed.
How puppies develop senses
In those early weeks while still deaf and blind, puppies navigate their world through touch, smell, and taste. They use their senses of temperature and motion as well. After their ears and eyes open, the puppies are flooded with new sights and sounds. It takes time and experience interacting with their environment for puppies to make sense of all the new sensory information.
Dogs Have An Excellent Sense of Time
In addition to their super sniffers, dogs also have an incredible sense of time. Here are some ways dogs demonstrate their internal clocks and perception of time:
Dogs can tell time
Many dogs learn to identify when it’s time for meals or walks based on cues in their environment. They associate certain signals like leashes coming out or food bowls being filled with it being time for an activity.
Dogs know your daily schedule
Over time, dogs become tuned in to your patterns and schedule. They know when to expect you up in the morning, when you’ll return from work, and when it’s bedtime based on the household routine. Dogs are creatures of habit and familiarity.
So while dogs may not wear wristwatches, their ability to recognize and anticipate fixed events in their daily life is pretty remarkable. Dogs have an innate sense of time that helps provide consistency and comfort.
Dogs Dream Just Like Humans
When dogs enter REM sleep, they experience vivid dreams just like humans do. Here’s what we know:
REM sleep in dogs
Dogs have the same sleep stages as humans – slow wave sleep and REM (rapid eye movement) sleep where dreaming occurs. Dogs spend about 10% of their sleeping time in REM.
What we know about dog dreams
It’s hard to know exactly what dogs dream about. But we do know dogs have active brain waves during REM sleep just like humans. Their breathing becomes irregular, their limbs twitch, and you may see body movements or facial expressions. It certainly seems our furry friends enjoy an active dream life!
Observing your dog deep in dream state can give you a glimpse into their inner world. Just look for those adorable leg twitches and soft woofs to tell they are dreaming away.
Dogs Have A Sixth Sense
Have you ever witnessed your dog suspiciously barking at an empty room, or nervously pacing right before an earthquake? Many dog owners have stories that suggest dogs have almost a sixth sense about things we humans can’t perceive. Here are some examples of dogs’ unexplained instincts and intuition:
Evidence of a canine sixth sense
- Dogs detecting health conditions like seizures or cancer
- Dogs alerting owners to danger before something happens
- Dogs knowing when their owner is coming home
Possible explanations
- Superior dog senses detecting subtle cues
- Sensitivity to changes in the environment
- Ability to smell chemical signals like pheromones
- Extrasensory perception and psychic perception
Whatever the cause, it’s clear dogs sometimes understand things about the world that humans can’t explain. Chalk it up to canine intuition!
Dog Noses Are Like Fingerprints
Just like human fingerprints, the pattern of ridges and creases on a dog’s nose is unique to each dog. Even dogs of the same breed will have different nose prints. Their distinctive nose print is determined by how the collagen and blood vessels form in utero during development.
So next time you look at your dog’s cute nose, remember that the markings are one-of-a-kind. Your dog’s nose print is special to only them!
Dogs Have Clean Freak Tendencies
You may have noticed some funny canine habits that seem almost obsessive, like spinning before lying down or licking their paws constantly. These behaviors actually have a purpose – dogs are clean freaks! Here are some ways dogs like to keep tidy:
- Licking their paws keeps them clean after walking outside
- Circling before settling flattens debris so they have a clean bed
- Scratching after going potty helps bury their waste
- Biting at fleas or fur helps groom their coat
- Rubbing on grass or carpets absorbs odors and removes dirt
While dog cleanliness habits can seem over the top at times, they stem from sensible instincts. After all, dogs aim to keep foul scents and dirt away – something their owners can appreciate too!
