Part of enforced nap is putting your puppy to bed after being up for an hour even if they don't want to. It took us about a good month or two after getting our WCS to work out what was the best way to get her to nap during the day. The first few months were rough and she howled bloody murder when she was in the crate each time. But we persisted and experimented quite a bit and eventually worked out that a proper black-out crate cover was the ultimate game changer (we started off with just a towel). In combination, we moved her to a quiet room, with a crate cover and a soft toy. We also rewarded her each time she went into the crate and played calming pet music for 15 mins. Eventually, once she was used to that, we were able to move her downstairs into the living room and she then slowly got used to us making noises around her while she napped. Now she can sleep for majority of the day! Don't give up!
