My puppy is 10 weeks old and has been with us for 7 days. She's in a crate at night. She woke at 3am and then each hour on the first night - we went to her every time. Second night she slept through to 6am and since then we don't hear a peep from her at night. However at 1 year old your friends dog is too old to start crate training.
My dog slept through from his second night with us a day or two less than 8 weeks old. First night he did a bit of crying for half an hour, then a couple of whimpers an hour or so later. Since then, any noise from him at night is either snoring or a warning sign of diarrhoea/vomiting.
I'm afraid I was a bit heartless with him. On breeders advice he slept in a crate and the rule from day 1 was that only silent dogs get let out. So when he whimpered I checked on him, spoke quietly to him and left the room. He decided that it was less hassle to just sleep.
At 1 year crate training would still be doable, but getting him to settle may take longer as he's now got into bad habits. But if your friend is consistent, patient and strict about the new routine he should settle down fairly quickly.
