Yapping proudly as the smallest dog in the world, the Chihuahua ranges from one to six pounds in weight. The Chihuahua also has a romantic history to be proud of, and while the precise history is not known, stories and speculation abound about Chinese bantamizing, Spanish explorers, or roots in the Portuguese pariah types. Whatever the true story, the Chihuahua himself knows and seems content not to confess – it is quite obvious that the idolized Chihuahua knows he is important and enjoys his exclusive information. While many dogs are relieved to not be yclept “toy dogs,” the Chihuahua enjoys this classification fully. A toy dog with a lot of heart and spunk, the breed can be long-coated or smooth and comes in any soldi, bi, or tricolor pattern.
