The history of the Chihuahua is has been debated for years. There are many different beliefs as to their origin. One such belief is that the Chihuahua is a descendent of the fennec fox, Fennecus Zerda, which was a small desert dwelling animal from Africa. There are some very striking similarities between the two animals. The fennec, unlike other foxes, chooses to live in groups. It is also commonly know that Chihuahuas prefer to have other Chihuahuas as company. Both the fennec fox and the Chihuahua also prefer to chase and eat small insects, rodents, and lizards. The fennec fox was also known to have very poor dental health which is unfortunately another common trait of the Chihuahua.
