Objective: To describe a case of a suspected anaphylactoid reaction to mannitol in a dog.

Case Summary: A 1-year-old, neutered female French Bulldog was anesthetized for a T12-T13 dorsal laminectomy surgery for a previously diagnosed spinal arachnoid diverticulum. Perioperatively, the spinal cord appeared grossly edematous, and IV mannitol administration was elected.

Flash pulmonary oedema associated with paroxysmal supraventricular tachycardia: report of two cases.

Case Summary: We describe two cats that had episodic tachypnoea and increased respiratory effort during periods of paroxysmal supraventricular tachycardia (SVT). Thoracic radiographs at the time of clinical signs were consistent with cardiogenic pulmonary oedema. Echocardiography following stabilisation revealed a hypertrophic cardiomyopathy phenotype with normal left atrial size in both cats.
