Golden Retriever survives massive phenobarbital overdose

A Golden Retriever in Knoxville, Tennessee, survived a massive phenobarbital overdose after emergency clinicians and veterinary toxicology experts coordinated intensive supportive care. According to Pet Poison Helpline, the dog, Lucy, ingested an estimated 80 to 90 phenobarbital tablets that had been prescribed for a visiting dog with seizures. She arrived at Animal Emergency and Specialty Center of Knoxville unresponsive, hypothermic, bradycardic, and without a readable blood pressure, then was intubated, warmed, and treated with IV fluids and ongoing monitoring over four days. Pet Poison Helpline said the case underscores how quickly unsecured medications, including those belonging to another household or visiting pet, can become life-threatening. (petpoisonhelpline.com)

Why it matters: For veterinary professionals, the case is a reminder that rapid stabilization and early toxicology consultation can be decisive even when decontamination opportunities have likely passed. Phenobarbital is widely used in canine seizure management, has a long and variable elimination half-life, and can produce profound CNS and cardiopulmonary depression in overdose, making prolonged supportive care and serial reassessment essential. It also reinforces a practical client-education point: “out of reach” often isn’t secure enough, especially with flavored or chewable medications and in homes with multiple pets or visiting animals.

What to watch: Expect continued emphasis on medication-storage counseling, poison-control partnerships, and household risk screening during discharge and refill conversations. (petpoisonhelpline.com)
