The Science of Dogs

Thanks! Share it with your friends!

The dog is the ultimate human creation. With 400 breeds and counting, the dog is more varied in size and behavior than any other species on the planet. National Geographic looks at man’s evolutionary manipulation of dogs’ appearance, talents and temperament—and the accelerating efforts to create breeds to suit our needs (more than 80 percent of today’s breeds did not exist 150 years ago). From desirable traits like supersensitive hearing and smell to the unintended consequences of genetic diseases, learn how nature and man have partnered to deliberately create new and specialized versions of man’s best friend.

Dogs aren’t man-made, natural dogs are made from God, but man cross-breed 2 different dog breeds to make 1 weird breed like suppose you had a husky and a pomeranian= a pomsky, that is not officially man-made but man made that happen and God was the one who formed and created him/her in the natural female dog’s womb so I don’t know what he is talking about with “we” mad this, and “we” made dogs do that and blabbity-blah!

German shepherds are a good representation of combining a multi tasking dog; combining herding dogs with mountain dogs the German shepherd was bred to both herd the sheep, and also guard them from predators.. a big reason why most working line German shepherds are natural guardians. Rhodeasian ridgeback is another example of a multi purpose dog that was bred to hunt lion in all sorts of terrain and weather. I love all dogs! Truly mans best friend!!

Why is it that there is always some idiot in the comments section comparing dogs to cats? I personally have dogs, but doesn’t mean I don’t think cats deserve respect and love. More cats are killed in shelters than dogs overall. Many by gassing and mass euthanization. All living things feel pain in one way or another. It tears me up when I see an animal in pain.

It looks like a fairly young Great Dane. Nice to meet a fellow Husky owner.

The thing they tried with the wolf and the dogs, to check if he’s getting guided by the human, I must say that it’s very fimiliar to me.
I own a siberian husky, a very close (genetically) breed to the wolf, and he’s also very independent,most of the times he doesn’t wait for my help. it’s a very common quality of the breed.

TalTxD says:

what dog breed in 1:39 , the black and white one?

teakbridge101 says:

Wolf: Nature’s miracle

Poodle: Man’s attempt to equal Nature.

Equals mega-suck.
