Plain-English summary
A 5-year-old female Labrador retriever started having rapid breathing, a fast heartbeat, and trouble walking after accidentally eating a large amount of phenylpropanolamine, a common decongestant. Tests showed serious heart issues, including abnormal heart rhythms and damage to the heart muscle. Thankfully, after treatment and monitoring, all of her heart problems and other symptoms improved and resolved within six months.

Abstract
A 5-year-old, 29-kg, female Labrador retriever developed tachypnea, tachycardia, and ataxia following ingestion of approximately 48 mg/kg of phenylpropanolamine. Initial diagnostic tests showed multiform ventricular tachycardia, left ventricular dilatation with a focal dyskinetic region in the dorsal interventricular septum, and elevations in creatinine kinase and cardiac troponin I. All abnormalities resolved within 6 months. The transient electrocardiographic, echocardiographic, and biochemical abnormalities were consistent with myocardial necrosis from infarction or direct catecholamine-induced myocardial toxicity.
