I'd make it a feat that allows a character to train a specific mount to function when he is riding or handling it as if it had effective Hit Dice (including BAB, base saves, extra feats, and ability score increases) equal to Handle Animal ranks -5 (or character level -2 for those with maxed-out Handle Animal ranks).
This is a special use of the Handle Animal skill and requires two weeks' training, a Handle Animal check with a DC of 15 + effective Hit Dice, and an animal already trained for war or for the special purpose of combat riding.
The animal does not actually have these effective Hit Dice, but its special training allows it to respond to its trainer's visual or spoken cues and act as if it had. If it is separated from its trainer, it functions as a normal animal of its kind.
This feat should be available from character level 6, so it should have a prerequisite of Handle Animal 9 ranks.
