GENERAL DOGGY FACTS - Dog intelligence is the ability of a dog to learn, think, and solve problems. Certain breeds, like Border Collies, Poodles, German Shepherds and Golden Retrievers, are generally easier to train than others. - The common saying that one year in a dog's life is the equivalent of 7 in a human's isn't exactly true. A more accurate calculation is as follows: At one year, a dog is the equivalent of 16 human years; at two dog years they are 24 human years; at 3 dog years, 30 human years; and for every dog year after that, add 4 human years. - An adult dog has 42 teeth. - Most people think that dogs sweat by salivating, but they actually sweat through the pads of their feet. - Contrary to popular belief, dogs are not color blind but can, in fact, see color. They distinguish between blue, yellow, and gray, but probably do not see red and green. However, their color scheme is not as vivid as ours and can be likened to our vision at twilight. - Cats can see a lot better than dogs. In fact, dogs first distinguish objects by movement, then brightness, and finally by shape. - 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 have a sense of smell that is one of the keenest in nature. The canine nose works one million times more efficiently than the human nose. - Dogs (and cats), like people, are either right-handed or left-handed; that is, they favor either their right or left paws.
