Acute onset of generalized tremors, mild ataxia, and hyperesthesia in a young dog after presumptive ingestion of a giant sea hare belonging to the genus Aplysia

Objective To describe an unusual case of canine toxicosis from presumptive sea hare ingestion, its management, and outcome. Case Summary A young dog was treated for acute toxicosis after partially ingesting a giant sea hare washed up on a beach. The primary symptoms of generalized tremors, mild ataxia, and hyperesthesia occurred rapidly within 20 minutes of ingestion. Decontamination procedures were performed early and the dog made a full recovery within an approximate period of 6 hours. New or Unique Information Provided Sea hare toxicosis should be considered as a potential cause of acute onset of tremors, ataxia, and hyperesthesia in previously healthy dogs living in coastal areas.
