Pet Library: Dogs

Dogs can be seen walking along our city parks, romping in backyards, wandering stray in search of food, napping in our living rooms, begging at our tables - just about anywhere in society. In most places, they are known as the family dog.
It is estimated that there are 150 million members of the canine population in the world, and there is great variability, with more than 300 breeds throughout the world - from the Great Dane at 150 pounds (67.5 kilograms) to the Chihuahua at 1.5 pounds (0.68 kilgrams).
