According to scientists, the relationship between dogs and humans could have endured for tens of thousands of years. Dogs were the first animals domesticated by people.
New research has found that the close bond started in Ice Age Europe between 19,000 and 30,000 years ago. That was when wolves, ancestors of domestic dogs living today, were first tamed by ancient hunter gatherers, according to new genetic evidence.
All dogs, regardless of breed, are direct descendants of wolves and technically of the same species. There are more than 150 dog breeds, divided into 8 classes: sporting, hound, working, terrier, toy, non-sporting, herding, and miscellaneous.

Nearly all but two breeds of dogs have pink tongues: the Chow Chow and the Shar-pei both have black tongues.
Dogs are capable of locating the source of a sound in 6/100ths of a second by using their swiveling ears like radar dishes. Dogs’ sense of hearing is more than ten times more acute than a human’s!
Dogs can smell about 1,000 times better than humans. While humans have 5 million smell-detecting cells, dogs have more than 220 million. The part of the brain that interprets smell is also four times larger in dogs than in humans.
Spaying/neutering your dog before the age of 6 months can help prevent cancer in your dog. If a dog isn’t spayed or neutered, a female dog, her mate and their offspring can product 67,000 dogs in 6 years. About 1/3 of the dogs that are surrendered to animal shelters are purebred dogs.
Eighty percent of dog owners buy their dog a present for holidays and birthdays. More than half of them sign letters and cards from themselves and their pets. It has been established that people who own pets live longer, have less stress, and have fewer heart attacks.
