I mean i think lizards and snakes can recognize you from your scent or w/e, that doesn't mean that it loves you...dogs can express emotion, i can put food infront of my dog and know he won't bite me...dogs are capable of loving and they are loyal...and i dont think snakes or lizards can, they don't come to you if they feel scared or anything like that, they don't protect you...idk just thought i'd make that point, idk if anyone else has or not...just sayin.
