english: As geneticists would like you to think, perhaps the mother had the "bad mother" gene that caused her pups to be stressful, and then it was passed from generation to generation; it's all determined by genetics.
non_english: Genetičari bi vam rekli da je majka možda imala gen "loše majke" koji je uzrokovao da njeni mladi budu pod stresom, a potom se preneo s generacije na generaciju; sve je genetski predodređeno.
