There is a lot that you know about your dog and his fellow dogs. However, these fun facts are less well known. Or did you know that the largest dog in the world was almost 1.12 meters tall? We present you with 15 dog facts that you are guaranteed not to know yet.
1. Dogs have three eyelids
Did you ever think that dogs like us have two eyelids? Thought wrong! Because in addition to the two eyelids that can be seen, there is a third eyelid in dogs – it ensures that the eye remains protected and moist.
2. Two breeds of dogs have black tongues
Most dog breeds have tongues similar to those of humans: light pink, not so with Chow Chow and Shar-Pei. They are the only breeds of dogs with a black tongue. Why this so has not yet been scientifically explained.
3. Almost every third Dalmatian is deaf in one ear
The Universities Federation for Animal Welfare, according to 15 to 30 per cent of all Dalmatian deaf in one ear. The reason for this is a gene that is also responsible for the piebald coat pattern. Around five per cent cannot even hear anything in either ear. The association, therefore, advises that all Dalmatians have their hearing examined – because affected Dalmatians have a higher risk of injury, for example, in traffic.
4. The Beatles for Beagles
In a 2013 interview, Beatle Paul McCartney revealed that he had hidden a soundtrack for dogs on the record “Sergeant Pepper”. In the last song on the album, “A Day In The Life”, there is an extremely high-pitched whistle that the human ear cannot hear – but it is for dogs. The dog sound was the result of a conversation with one of the sound engineers.
5. The largest dog in the world
The largest dog in the world was a Great Dane named Zeus. According to the Guinness Book of Records, he measured an impressive 1,118 meters. When he stood on his hind legs, Zeus was 2.23 tall! With 70 kilograms and almost endless legs, he made an impressive figure. Unfortunately, the recorded dog died in 2014 at the age of five.
6. Three dogs survived the sinking of the Titanic
Quite a few people died in the luxury ship’s accident at the beginning of the 20th century. But there were also some pets on board. Three dogs are said to have survived: two Pomeranians and a Pekingese. For example, a woman wrapped her Pomeranian puppy in a blanket so that everyone thought she was carrying a baby. This is reported on the “Vetstreet” page.
7. Dogs are about as intelligent as two-year-old children
According to American Psychological Association, the average dog can learn up to 250 words and gestures – about the same amount as children by the age of two.
8. Dogs drink with the bottom of their tongue
Researchers at Virginia Tech University played and analyzed footage of drinking dogs extremely slowly. The result: dogs drink differently than we previously thought. Because the four-legged friends don’t just “slouch” – they move their tongues very precisely and at high speed to shovel water into their mouths. To do this, they fold their tongues down underwater, away from their noses. The enormous speed also creates a small column of water from the bowl to the dog’s mouth.
9. Dogs are warmer than us
The normal body temperature is between 38 and 39 degrees. From a temperature of around 39.4 degrees Celsius, one speaks of fever in dogs.
10. Dogs dream
Human and dog brains function similarly during sleep. Dogs also have so-called REM phases in which they dream – just like humans. For example, if you notice that your dog twitches or moves its paws while sleeping, he is likely dreaming.
11. Dogs have 18 muscles in their ears
The hearing of dogs is more pronounced than that of humans – this is shown, among other things, by the example of the Beatles song mentioned above. No wonder dogs have twelve more muscles than we do to move their ears. This allows them to turn and lift their eavesdroppers independently of one another to perceive sound waves as efficiently as possible.
11. Dogs smell 10,000 to 100,000 times better than humans
Also, when it comes to smell, dogs are a lot ahead of us. This example helps to illustrate this: In a mountain of socks with two million clean socks, you can sniff out a single dirty sock.
12. Dogs are believed to be able to sniff out diseases
Dogs’ sense of smell is so fine that they can also detect drugs, people or other material things, for example. You can probably even train them to sniff out cancer cells. Because as the portal “American Veterinarian” reports, there are already some cases of dog owners whose four-legged friends are said to have recognized cancer in their breath or on their skin.
