if it is only a pitbull it will bite your arm like a police dog because you will go full guard, as i said take your other hand, gauge it's eye and use it as a holster like a bowling bowl, it's biting your other arm so you use it to lift and you elbow it into the ground with the arm it's biting and push it's skull with the eye you're gouging  literally only risk is diseases that's if you have no weapons
