A 5-year-old, neutered male Labrador retriever presented in the evening with a history of vomiting, ataxia, and generalized weakness.
History. That morning the owner found evidence that the dog had raided the trash can sometime during the night. The owner was not concerned at the time because he did not believe that there had been anything harmful in the trash that the dog could have ingested.
Diagnostics. On physical examination, the dog was depressed and reluctant to stand, had mild hindlimb tremors, and was hyperthermic (105.5º F). Abdominal palpation was unremarkable. Bilateral patellar reflexes were slightly exaggerated, but the rest of the neurologic examination was unremarkable. Clinical blood testing showed that serum lipase and serum alkaline phosphatase levels were approximately twice the high normal value. A complete blood count showed elevated white blood cells (22,450 cell/µl) with mature neutrophilia.
