difference between tobiano and overo
Tobiano is generally a large patch of clearly lined color on a white coat. The white will cross the topline between the wither and the tail. Generally tobiano's have a dark colored face and stockings or socks, though overo's can have them too if they have the sabino gene. Many tobiano colored horses also have dual colored tails.
A common misconception is that if the white markings cross the center of the back, between the withers and the tail, then it is a tobiano, if not, itâs an overo. This is simply not true. Many minimally marked tobianos do not have white that crosses the back, and many overos (especially splashed white overos) do.
