A Golden Retriever puppy puppy named Goose slept through an entire puppy training class before his instructor woke him up. The article was powered by Yahoo Scout, which uses AI to generate key points but may not always match what’s in the article. While adult dogs sleep more than their adult counterparts, puppies can sleep for up to 20 hours a day.

Despite this, Goose's sleepiness has been noted as a significant difference from adult dogs who typically sleep around 16 hours per day.
