Interesting fact, there is a special breed of dogs in Vietnam, it's called Phu Quoc Ridgeback. They are the only breed of dogs with their roots in Vietnam and one of only three breeds that have a strange ridge of hair running along their spine in the opposite direction from the rest of the coat. They used to be hunting animals but now they are domesticated and their puppies are very expensive abroad.
There are also spectacular sunsets in Phu Quoc due to its location.
