A cocker spaniel puppy named Gösta is drawing attention after videos and reports show him passing out or falling asleep whenever he becomes too excited. Several outlets describe his condition as narcolepsy-like, with his behavior changing during moments of high stimulation.

The articles frame the pup’s reactions in the context of the breed’s typical temperament. Cocker spaniels are often described as having a cheerful, “merry” disposition, which can make excitement common during play or interaction. In Gösta’s case, that enthusiasm appears to trigger episodes where he loses consciousness and rests shortly afterward.

While the sources focus on the same central phenomenon—sleepiness triggered by excitement—differences largely come down to wording and emphasis. Some describe him as “passing out,” others as “falling asleep,” and the coverage uses different titles to highlight the recurring clip or the puppy’s name. All accounts present the puppy’s unusual reaction as the main point of interest and do not present competing claims about the underlying cause.
