When Dogs Get High: Stories from the Vet’s Office and Lessons Learned Real-life anecdotes from veterinarians on treating dogs exposed to THC, and key takeaways for pet owners.
As cannabis legalization expands, veterinarians are encountering an increasing number of cases involving dogs that have inadvertently ingested THC, the psychoactive component of marijuana. Such incidents often result in significant health issues for the animals and considerable emotional and financial distress for their owners. Through real-life anecdotes from veterinary professionals, we can glean valuable lessons on prevention, recognition, and response to THC exposure in dogs.
Case Study-1: Oscar’s Unexpected Encounter
In August 2024, Stephen Davidson’s eight-year-old West Highland Terrier, Oscar, became lethargic and unresponsive after a routine beach walk in Sheerness, Kent. Concerned by Oscar’s sudden change in behavior, Stephen rushed him to an emergency veterinary clinic. The attending veterinarian diagnosed Oscar with THC intoxication, likely from ingesting discarded cannabis on the beach. Oscar required intravenous fluids and activated charcoal to eliminate the toxin from his system, resulting in a £900 veterinary bill. This incident underscores the importance of vigilance during walks and the necessity of immediate veterinary attention when unusual symptoms arise.

Case Study-2: Coco’s Close Call
Coco, a nine-month-old Yorkie-Havanese mix, was rushed to an emergency animal hospital after her owners noticed alarming symptoms, including lethargy and incoordination. The veterinarian confirmed THC toxicity, attributing it to accidental ingestion of marijuana. Coco’s treatment involved supportive care to manage her symptoms, and she eventually made a full recovery. This case highlights the critical role of prompt veterinary intervention and the need for pet owners to be aware of their surroundings, especially in areas where cannabis use is prevalent.

Veterinary Insights and Lessons Learned
Dr. Carly Fox, a senior veterinarian at BluePearl Pet Hospital in New York City, explains that dogs are particularly susceptible to THC due to their smaller size and different metabolism compared to humans. She emphasizes that even small amounts of THC can lead to severe symptoms in dogs, such as vomiting, tremors, and seizures. Dr. Fox advises pet owners to be transparent with their veterinarians about potential THC exposure, as this information is crucial for accurate diagnosis and effective treatment.

Preventive Measures for Pet Owners
To prevent accidental THC ingestion, pet owners should store cannabis products securely, out of reach of pets. This includes edibles, which may be enticing to dogs due to their resemblance to regular food items. During walks, especially in public areas, owners should monitor their dogs closely to prevent them from picking up unknown substances. Educating all household members about the dangers of THC to pets is also essential in preventing accidental exposure.
Recognizing Symptoms of THC Toxicity
Common signs of THC toxicity in dogs include lethargy, incoordination, dilated pupils, urinary incontinence, vomiting, tremors, and agitation. These symptoms can appear within 30 minutes to an hour after ingestion. If a dog exhibits any of these signs, especially after potential exposure to cannabis, immediate veterinary attention is crucial.

The Importance of Prompt Veterinary Care
Timely veterinary intervention can significantly improve outcomes for dogs exposed to THC. Treatment may involve decontamination procedures, such as inducing vomiting or administering activated charcoal, and supportive care to manage symptoms. In severe cases, hospitalization may be necessary to monitor and stabilize the dog’s condition. Delaying treatment can lead to more severe health issues and prolonged recovery times.
Conclusion
The rise in THC toxicity cases among dogs serves as a critical reminder for pet owners to exercise caution and responsibility regarding cannabis products. By learning from real-life veterinary experiences, owners can better understand the risks, recognize symptoms, and take preventive measures to protect their pets. Open communication with veterinarians and prompt action in the event of exposure are key to ensuring the health and safety of our canine companions.
