I assume you mean the oldest horse as in the oldest horse found in the fossil records. Eohippus was roughly the size of a modern day fox, it was due to it's environment and diet. Eohippus was a browser in the beginning and had multiple toes to walk easily over the marshy ground of it's forest environment. The smaller size would have enabled it to run and hide in the forest far more easily than a larger animal could. As the environment changed so did Eohippus, eventually evolving into a much larger animal over time.
