If I knew the puppy needed to pee then I spent as much time outside as needed and threw a praise party when it finally happened, sometimes it was 5 seconds and sometimes it was over 30 minutes.
The fact he was refusing and then howling sounds like he might have a UTI or something else causing him pain
