Plain-English summary
A dog was brought in showing signs of fast heart rate, rapid breathing, weakness, and vomiting after being exposed to metaproterenol, a medication that stimulates the heart. Tests showed the dog had abnormal heart rhythms and increased heart function. The veterinarian treated the dog with beta-blocker medications, propranolol and atenolol, which successfully resolved the symptoms. This case highlights that metaproterenol intoxication, while rare, can lead to serious heart issues in dogs.

Abstract
Intoxication with metaproterenol, a mainly beta-2 selective agonist, was diagnosed in a dog with tachycardia, tachypnea, weakness, vomiting, and a history of exposure to the drug. Electrocardiography and echocardiography disclosed sinus tachycardia with episodes of ventricular tachycardia and exuberant systolic ventricular function, respectively. Administration of the beta blocking drugs propranolol and atenolol led to resolution of the clinical signs. Excessive sympathetic stimulation caused by metaproterenol is an unusual intoxication in dogs.
