Not long after having a short anesthetic procedure to remove a skin growth, 8-month-old Rottweiler Nico became unusually sleepy and wobbled when he walked. By the next day, Nico could not stand up or walk at all, and he was brought to SEVN for a thorough exam. We diagnosed him with narcolepsy/cataplexy. Narcolepsy involves “sleep attacks” and drowsiness, while cataplexy is a short period of paralysis caused by excitement. We treated Nico with medication, and he was once more alert and able to stand and walk on his own.
