As far as I understand, since mordre is an -re verb, its conjugation in the "je" form is "je mords". But I have seen written, and Google translate confirms, "je ne mord pas".
Where did the s go?
Google Translation can be wrong sometimes, in this case the valid conjugation is :
je ne mords pas
Je mords Tu mords Il/Elle/On mord Nous mordons Vous mordez Ils/Elles mordent
