No, there most likely is no Dutch in him at all. Two copies of the Vienna gene gives you a white rabbit with blue eyes. A rabbit that has only one copy of the Vienna gene usually has some white markings, and may or may not have blue eyes. This is what is known as Vienna Marked. For some reason, the white markings of a Vienna marked rabbit often look a lot like the markings of a Dutch rabbit; in fact, we used to call them "psuedo-Dutch." It shouldn't be confused with the real Dutch, it doesn't work with the real Dutch, it just happens to resemble it somewhat.
