The above dog breeds are commonly believed to be extinct. Very little has been written about them and the dates of their extinction are largely unknown. As with all creatures who become extinct, there can be a variety of reasons that a particular dog breed suddenly ceases to exist. Sometimes it’s physical- the result of a disease that a particular breed is susceptible to, or a weakness in their constitution that makes caring for them difficult, causing people to lose interest and instead focus on other breeds. Extinction can also be caused by drastic cultural change, such as when the Cuban Revolution almost rendered the adorable Havanese extinct. In Japan, the Akita almost became extinct due to excessive dogfighting during the Meiji period (the late nineteenth century and early twentieth century). This noble breed was threatened again during World War II when starving Japanese citizens relied on his meat to sustain them. But extinction isn’t always the result of calamity. The particular traits inherent in one dog breed may no longer be valued by society. Without active breeding programs, these domesticated animals no longer have viable populations. While certain breeds such as the New Guinea Singing Dog and the Manchester Terrier have been brought back from near extinction, many others are lost to history.
