the difference between "Fila" and EM should be VERY apparent as Filas are smaller, longer than they are tall, longer muzzle, lower ear set, etc. the problem is that some dogs called Filas were already mixed so you have multiple different dog types being called fila... so the question is now harder to answer. ther eis no set age where one can say for certain. certain bloodlines come in sooner than others and other bloodlines never come in to real temperament.... all depends on what you got and then again if it is a mix then you might never get any fila temp. BTW I have never seen an EM with white on its face before but I have seen many a fila with that marking...just saying.
