whats the difference between a dodge tide and a neap tide?

Answer 1

the relative positions of the earth and moon for neap, and land structures for dodge.

Around new and full Moon when the Sun, Moon and Earth form a line (a condition known as syzygy), the tidal forces due to the Sun reinforce those of the Moon. The tides' range is then at its maximum: this is called the "spring tide", or just "springs" and is derived not from the season of spring but rather from the verb "to jump" or "to leap up". When the Moon is at first quarter or third quarter, the Sun and Moon are at 90° to each other and the forces due to the Sun partially cancel out those of the Moon. At these points in the Lunar cycle, the tide's range is at its minimum: this is called the "neap tide", or "neaps".

A "dodge" tide is an extended period of tidal inactivity, commonly known to fishermen, particularly in the Southern hemisphere. Thier origin is more complicated and has to do with local topography.
