As far as conformation goes, that's kind of silly, in my viewpoint, for the Fila, as the Fila breeders who are true to the heritage of the working Fila breed for what's inside the dog first; temperament, heart, ojeriza, fearlessness, absolute loyalty, intelligence, discernment and judgment, working abilities, a high degree of self-determination and, yes, a good streak of stubbornness; then for physical capabilities; strength, stamina, agility, speed, a ridiculously high pain threshold, soundness, health. The last consideration is what the dog looks like or how long it is from here to there, or where the ears are set exactly or how far apart the eyes are.
