1. Dogs Have Unique Nose Prints
Just like human fingerprints, every dog's nose print is unique. These distinct patterns can be used to identify individual dogs. Despite the uniqueness of nose prints, they are not widely used in practice compared to more conventional methods like microchipping and ID tags. This is mainly due to the practicality and ease of use of other methods. However, the concept remains an interesting and viable option for dog identification.
2. Dogs Can Understand Up to 250 Words and Gestures
Studies show that the average dog can learn about 165 words, but highly intelligent breeds like Border Collies can understand up to 250 words and gestures. Determining the "most intelligent" dog can be subjective and varies depending on the criteria used. However, a Border Collie named Chaser is one of the most notable dogs often cited for intelligence. Chaser, owned by Dr. John W. Pilley, a psychology professor, was frequently cited as the smartest dog in the world. Chaser learned the names of over 1,000 objects and could retrieve them by name.
3. Dogs Dream Like Humans
Just like humans, dogs need a comfortable and supportive bed to ensure they get quality sleep. They experience similar stages of sleep as humans, including the REM stage, where dreaming occurs. Many dog owners enjoy watching their dogs while they dream, noticing the subtle movements and sounds they make. If you see your dog twitching or moving in their sleep, they might be dreaming about chasing a squirrel or playing fetch!
4. A Dog’s Sense of Smell Can Be Trained for Detection
A dog’s sense of smell is estimated to be between 10,000 to 100,000 times more acute than a human's. Dogs can be trained to detect various substances, including drugs, explosives, and even certain types of cancer. Their keen sense of smell is used in medical detection, and search and rescue missions.
5. Dogs' Eyesight and Colour Blindness
Dogs have different visual abilities compared to humans. While they have excellent motion detection and night vision due to a higher number of rod cells in their retinas, their colour vision is limited compared to humans. Dogs are dichromatic, meaning they primarily see shades of blue and yellow. They have fewer cone cells responsible for colour vision than humans, which affects their ability to distinguish between certain colours, particularly reds and greens. Despite this, their keen sense of smell and hearing compensate for any visual limitations, making them well-adapted hunters and companions.
6. Dogs Can Hear Higher Frequencies Than Humans
Dogs can hear frequencies as high as 65,000 Hz, while humans can only hear up to about 20,000 Hz. This ability allows them to hear sounds that are imperceptible to us. So, it's quite possible that when our dogs stare out of the window and we don't hear anything, they are responding to sounds at frequencies beyond our hearing range.
7. Basenji Dogs Don’t Bark
The Basenji, often referred to as the "barkless dog," doesn’t bark like other dogs. Instead, they make a unique sound called a "baroo," which is a combination of a yodel and a howl.
8. Dogs Sweat Through Their Paws
Dogs primarily regulate their body temperature by panting, but they also sweat through the pads of their paws. This is why you might notice wet paw prints on hot days. Cracked paw pads can be painful for dogs, especially if the cracks are deep or bleeding. This can affect their ability to walk comfortably and may lead to limping or reluctance to move. Cracks in the paw pads can create openings for bacteria, dirt, and debris to enter, increasing the risk of infection. Use pet-safe paw balms to keep the paw pads hydrated and prevent further drying and cracking.
9. Dogs Can Sense Time
Dogs have an innate sense of time. While they may not understand time in the same way humans do (they don’t use clocks or calendars), they have several mechanisms that allow them to anticipate and recognize patterns related to the passage of time. Dogs, like humans, have an internal biological clock that regulates their daily cycles of waking, sleeping, eating, and activity. This circadian rhythm helps them anticipate daily events. Dogs are also highly observant and can learn routines. They can pick up on environmental cues and associate them with certain events. As such, they can be trained to follow a schedule and often know when it’s time for their daily walk, meal, or when their owner is due to return home.
10. A Wagging Tail Doesn’t Always Mean a Happy Dog
While a wagging tail is often associated with a happy dog, the position and speed of the wag can indicate different emotions. A slow wag with a stiff posture can indicate aggression, while a broad, relaxed wag usually signifies friendliness.
11. Dalmatians Are Born Without Spots
Dalmatians are born completely white and develop their characteristic spots as they grow older. The spots usually start to appear within the first few weeks of life.
12. Dogs Have Three Eyelids
In addition to the upper and lower eyelids that humans have, dogs possess a third eyelid called the nictitating membrane, or "haw." This membrane is located in the inner corner of their eye and it helps protect the eye from debris, dust, and injury, acting as a transparent shield that can quickly sweep across the surface of the eye. The nictitating membrane also helps distribute tears over the eye, keeping it moist and lubricated. To keep your dog's eye clean, use a gentle eye cleaning solution or eye wipes. This helps remove any buildup of dirt, dust, or excess tears that may accumulate around the eyes, reducing the risk of irritation and infections.
13. Greyhounds Are the Fastest Dogs
Greyhounds can reach speeds of up to 45 miles per hour. Their incredible speed makes them excellent racers and hunters.
14. Dogs Have a Sense of Direction
Some dogs have an impressive ability to find their way home over great distances, using a combination of scent, sight, and an innate sense of direction. Some research suggests that dogs, like other animals, may have an innate ability to detect Earth's magnetic field. This could serve as an additional navigational aid, especially over longer distances. In the wild, dogs and their ancestors relied on their sense of direction for hunting, territorial defence, and finding water sources. This innate ability to navigate is passed down through generations and remains an essential survival skill.
15. Some Dogs Have Webbed Feet
Breeds like the Labrador Retriever and the Newfoundland have webbed feet, which makes them excellent swimmers. These breeds are often used in water rescue missions. While breeds with webbed feet are often strong swimmers, not all dogs are naturally proficient in water. It's crucial to prioritise safety, especially in unfamiliar or deep water. Introduce your dog to water gradually and provide positive experiences to build confidence. Always supervise your dog around water and put a dog life jacket on fido. Ensure that the jacket fits snugly but comfortably, allowing freedom of movement without restricting breathing or movement.
16. Dogs Can Detect Human Emotions
Dogs are very good at reading human emotions. They can pick up on subtle changes in body language, tone of voice, and even our scent to understand how we are feeling. They can sense tension, relaxation, nervousness, or calmness through the way a person moves, stands, or gestures. The tone, pitch, and cadence of a person’s voice convey emotions to dogs. Dogs can also recognize facial expressions, particularly those involving eye contact and mouth movements. They can distinguish between smiles, frowns, and other emotional cues.
17. Dogs’ Whiskers Are Highly Sensitive
A dog’s whiskers, also known as vibrissae, are highly sensitive to touch and changes in the air. Whiskers are primarily used to detect changes in their environment through touch and texture. They can sense subtle movements and vibrations in the air, alerting dogs to nearby objects, prey, or even changes in the weather. They help dogs navigate their environment, especially in the dark.
18. Some Breeds Are More Prone to Hiccups
Puppies, especially smaller breeds, are more prone to getting hiccups. This often occurs after eating or drinking too quickly, which can lead to swallowing air. To prevent hiccups and promote healthy eating habits, especially in fast-eating breeds, consider a slow feeder bowl. Slow feeders are specially designed bowls or feeding devices that encourage dogs to eat more slowly. They typically have ridges, obstacles, or puzzle-like designs that require dogs to work around to access their food.
19. Dogs Can Be Left or Right-Pawed
Just like humans are left or right-handed, dogs can also show a preference for using one paw over the other. You can test this by observing which paw they use first when playing or reaching for something.
20. Chow Chows and Shar-Peis Have Blue-Black Tongues
Most dogs have pink tongues, but the Chow Chow and Shar-Pei breeds are known for their distinctive blue-black tongues. This unique trait sets them apart from other breeds.
