Some interesting facts about dogs are that there are more than 150 dog breeds, an adult dog has 42 teeth, and they sweat through their foot pads rather than through salivating. Almost all dogs have pink tongues except Chow Chows and Shar-peis, which have black tongues.

All dogs are directly descended from wolves and are technically of the same species. Other interesting physical characteristics include the ability of dogs to locate the source of a sound in 6/100ths of a second, their muzzle whiskers that can sense minute changes in airflow, and the over 200 million scent receptors in their noses in comparison to the only 5 million that people have. Research recently revealed that dogs see in color, just not as vividly as people do.

Other interesting facts about specific dog breeds are that the Greyhound can reach a speed of up to 45 miles per hour, and the Basenji is the only dog breed in the world that is unable to bark. The most popular dog breeds in the United States are the Labrador Retriever, Golden Retriever, Beagle, German Shepherd and Dachshund. According to a recent survey, the most popular name for a dog is Max. Other popular names include Sam, Maggie, Zach and Molly.
