How to tell if your dog has ingested marijuana?

Updated: Sep 24, 2023


Puppies ingesting marijuana is far more common than you would guess. Every week puppies are missing from puppy class because they ingest marijuana and were at the emergency vet all night.


If you think your dog has ingested marijuana, it can be terrifying. Their heart rate can slow down, they are lethargic, falling and uncoordinated and even urinating on themselves. It’s terrifying. Dog’s can ingest drugs any time at a park or on a walk it only takes a second.


Ingesting marijuana can be harmful to dogs, and it is important to seek veterinary care if you suspect your dog has ingested any substance. Some common signs of marijuana toxicity in dogs include:


  • Changes in behaviour such as increased agitation, lethargy, or depression

  • Changes in sensory perception, such as appearing dazed or "out of it"

  • Increased sensitivity to light, sound, and touch

  • Changes in balance and coordination, such as stumbling or appearing unsteady

  • Vomiting and/or diarrhea

  • Decreased heart rate

  • Dilated pupils

  • Urinary incontinence


If you suspect that your dog has ingested marijuana, it is important to seek veterinary care as soon as possible. The veterinarian may induce vomiting and provide activated charcoal to help absorb any remaining toxin in the dog's system. In severe cases, hospitalization and supportive care may be necessary.


It is also important to keep marijuana and all related products, such as edibles, securely stored and out of reach of pets. If you have any concerns or questions about the health and well-being of your pet, it is always best to consult with a veterinarian.


In conclusion, it is important to be aware of the signs of marijuana toxicity in dogs and to seek veterinary care if you suspect that your dog has ingested the substance. Keep all marijuana and related products securely stored and out of reach of pets to help prevent accidental ingestion.
