Bow-wow! Dog facts by PicsForDesign.com.

Hello! Recently we made a post about cats. Now it’s time for amazing facts about dogs. Are you a cat person or a dog person? Tell us in the comments!wink
 
Dogs are not descended from modern wolves.
Dogs are descended from a species of wolf that disappeared thousands of years ago. Modern American and European wolves are its distant relatives, although they share 99% of their DNA with dogs.
 
The Saluki is the oldest known dog breed.
The Saluki is considered the oldest dog breed known to man. In ancient Egypt, they belonged to the royal families. They were treated with reverence while alive, and even mummified after death as pharaohs.
 
Dogs have a larger range of sizes than any other mammal.
Due to human intervention in natural selection, there is a huge difference in size between dog breeds – more than any other mammal, wild or tame.
However, there is a limit to the physical differences of dogs.
The entire physiology of the dog, from the Chihuahua to the Great Dane, is based on the body structure of the ancient wolf.

They have a second "nose".
It is known to science as the vomeronasal organ and is located between the dog's nostrils and the palate of the mouth.
Scientists are still not sure what dogs use it for.
Based on research on other carnivores such as cats, they may use it when they sniff scent marks left by other dogs.
 
Dogs can fall in love.
When a dog comes in contact with people or other dogs, oxytocin, the hormone of love, is released in its brain. This process is identical to what happens in the human brain when they hug or kiss.
 
Dogs don't feel guilty.
Many owners notice what they consider to be a "guilty look" in a dog, but science has shown that it's actually a reaction to the owner's body language. Guilt is a rather complex emotion. The dog is just worried that it will be punished, not knowing what it did wrong.

Dogs instinctively bond with humans.
Once a puppy learns that humans are friendly, its instincts tell it that the best chance of survival is to stick  to a human.
That's why many dogs get so nervous when they're alone: they might think they've been abandoned.
 
Having a dog in the house can protect owners from asthma and colds.
Research shows that children who live in families with dogs are less likely to develop allergies and get sick than children who are raised in families without pets.
 
Greyhounds are a twice famous breed.
Greyhounds are known not only as the fastest dog breed, capable of reaching 72 km/h, but also as the only dog breed mentioned in the Bible (referring to Proverbs 30:31; King James version).

"Anita" by Misticheskaya
 
Dogs can memorize hundreds of words.
An average dog is as easy to train as a human child and can learn between 200 and 500 words. Moreover, the dog can learn the basics of mathematics, for example, learn to count and arrange numbers in ascending order.
 
Dogs can smile.
Dogs smile, but not necessarily for the same reasons we do.
According to veterinary scientist Dr. John Bradshaw, a dog will smile to convince its owner to show it their love.
Therefore, dogs are not always happy when they "smile" – they may even feel a little anxious and need reassurance. So go show your puppy how much you love it.

Dogs are abnormally attached to people.
Most mammals experience simple emotions such as love, fear, anxiety, and pleasure, but dogs are now known to have special emotional responses to human attention.
Most owners are convinced that their dogs love them, and scientists now have evidence that affection for people actually determines much of a dog's behavior.
Recently, Professor Gregory Burns of Emory University was able to train dogs to lie down in an MRI scanner and was able to watch their brains' joyful reactions to photographs of their owners.
Dogs are also better than chimpanzees at understanding human body language.
