The dog-as-devil epithet traces back to the New Testament

Evidence

The dog was interpreted as a manifestation of the Devil, especially in medieval times. Christ’s tormentors were referred to as cruel, evil dogs in written and pictorial documents. As a derogatory epithet, “dog” might be applied to any enemy, especially to the Jews, an epithet that began with its use in the New Testament, where “dogs” may be seen metaphorically to refer to the Jews. — Sophia Rose Arjana, Muslims in the Western Imagination, 227
