well, if you look at it as though you are breeding a large breed dog with a small breed dog, it makes sense for the female to be the large breed as the offspring are going to be larger than typical for a smaller breed and could kill the lot of them. So if you were going to breed a st Bernard and a jack russell, it would, in theory and using a stepstool, be possible for the Male JR to impregnate the female SB.
However, many cross species matings have occurred- lion and tiger, donkey and horse, zebra and horse.
