Seattle is a hotbed for THC toxicity in pets
We love pets at DuBois Levias Law Group. There’s even a dedicated “Fur Babies” section under Our Team. Look at the sweet face of Delaney, and you’ll see why we panicked when he suddenly became disoriented and unsteady. A young receptionist at the emergency veterinarian knew the problem right away, because they see it all the time in Seattle: THC toxicity.
Trupanion, a pet insurer, found that Washington state recorded the highest frequency of marijuana toxicity per pet in the nation following legalization. Pet poison helplines have seen a nearly 800% increase.
Your pet is a big part of the family (plus an emotional support buddy). During divorce, when everyone is moving around and just not thinking straight, it’s important to mind your pets even more. Especially dogs, who tend to get into advanced eat-anything mischief.
THC affects pets far more intensely than it does humans. Dogs have more cannabinoid receptors in their brains, making them extra sensitive to it. Symptoms tend to appear about 30 minutes later after ingestion.
So store and use your weed responsibly. Keep pets away from edibles, dried cannabis, or even THC-laced food like oils, butter, or tinctures. Secondhand weed smoke can also be a problem.
Pet THC Toxicity
WHAT TO LOOK FOR:
- Dribbling urine (a hallmark sign in dogs)
- Lethargy or, in some cases, agitation
- Dilated pupils and glassy eyes
- Wobbliness or loss of coordination
- Drooling
- Low heart rate and body temperature
- Sensitivity to light, sound, or touch
- Vomiting
In severe cases, pets may experience tremors, seizures, or even fall into a coma
What to Do Next:
Call your veterinarian immediately or contact an emergency animal hospital.
Be honest about what your pet ate. Vets are there to help, not judge. Honesty can save your pet’s life.
Contact a pet poison hotline if you can’t reach your vet, such as the ASPCA Animal Poison Control Center.
Note the details — what type of cannabis, how much, and when it was consumed.
The faster your pet gets care, the better the outcome. Thanks to our quick-thinking vet, Delaney is up and wagging again.
But it’s a reminder of how quickly accidents happen.
FAQs
Can THC kill a dog or cat?
Death from THC alone is rare, but possible with very high doses. The risk increases significantly when cannabis is combined with toxic ingredients like chocolate or xylitol. Always seek veterinary care to be safe.
How long does THC poisoning last in pets?
Most pets recover within 24 hours with proper care. Severe cases involving large doses may take longer and require hospitalization.
What are the treatment options?
Treatment depends on severity, but most pets do well with supportive care. If caught early, your vet may induce vomiting or give activated charcoal to limit absorption. Pets are often kept in a quiet, low-stimulation space with IV fluids to stay hydrated, plus medications to control nausea, anxiety, tremors, or heart rate as needed. In severe cases, hospitalization and closer monitoring may be required until the effects wear off.
Will my vet report me for cannabis exposure?
Veterinarians prioritize your pet’s health, not legal consequences. Being honest about what your pet ate helps them provide the right treatment quickly.
What’s the first thing I should do if my pet eats cannabis?
Call your veterinarian or an emergency animal hospital right away. Quick action leads to a happy, healthy pet.
