Dehydration usually goes via an E1 mechanism. That is, the reaction takes place over two steps, the first being the formation of a carbocation intermediate. But if you had a primary alcohol the reaction wouldn’t go through a carbocation intermediate. This is because a 1º carbocation is too unstable to form.
