Cannabis and Pets: What Every Pet Owner Needs to Know
PetsSafetyCBD · 7 min read
If you use cannabis and have pets, you need to know this: THC is toxic to dogs and cats. What gives you a mild buzz can send your pet to the emergency vet. With edibles and concentrates becoming more common, pet poisonings are rising sharply.
How THC Affects Pets
Dogs have more cannabinoid receptors in their brains than humans. A dose that barely affects you can overwhelm a dog's nervous system. Cats are similarly sensitive but less likely to eat cannabis products.
Don't wait. Call your vet or the ASPCA Animal Poison Control Center: (888) 426-4435 ($75 fee)
Be honest with the vet. They're not going to report you. They need to know what and how much your pet consumed to treat them properly
Note the time and estimate the dose (how many mg of THC?)
Don't induce vomiting unless directed by a vet — it can cause aspiration
Most cases resolve in 12-24 hours with supportive care (IV fluids, monitoring). Fatalities are extremely rare but possible with very large doses or chocolate edibles (chocolate itself is also toxic to dogs)
The Biggest Risks
Edibles Are the #1 Danger
Edibles are the most common cause of pet cannabis poisoning because:
They smell and taste like food — dogs eat them eagerly
Doses are concentrated (a single 100mg brownie can seriously harm a 20-pound dog)
Chocolate edibles combine two toxins (THC + theobromine)
They're often left on counters, in purses, or in low drawers
Secondhand Smoke
Hotboxing a room with a pet inside can cause THC exposure through their lungs. Pets in small, enclosed spaces with heavy cannabis smoke can become intoxicated. Always smoke in well-ventilated areas away from pets.
Discarded Joints and Roaches
Dogs will eat joint roaches, especially outdoors. If you smoke flower, dispose of roaches where your pet can't access them.
CBD for Pets
Here's where it gets nuanced. CBD (without THC) may have benefits for pets:
Anxiety: Some evidence that CBD reduces stress-related behaviors in dogs
Pain: Preliminary research shows CBD may help with arthritis pain in dogs
Seizures: CBD has shown promise for seizure management in dogs
Important Caveats
Pet CBD products must be THC-free. Even small amounts of THC can cause problems. Look for "broad spectrum" or "CBD isolate" products specifically formulated for pets
Don't give human CBD products to pets. Human tinctures may contain sweeteners (xylitol is deadly to dogs), flavors, or higher-than-labeled THC levels
Talk to your vet first. CBD can interact with other medications. Your vet can recommend appropriate products and dosing
The industry is unregulated. Independent lab testing (Certificate of Analysis) is the only way to verify what's in the product
How to Keep Pets Safe
Store all cannabis products in sealed, elevated, pet-proof containers. Treat it like you would chocolate or medications
Never leave edibles unattended on counters, tables, or in open bags
Use child-resistant packaging — it's also dog-resistant
Don't smoke around pets in enclosed spaces
Clean up roaches and ash from outdoor smoking areas
Inform pet sitters and guests about cannabis products in the home
Bottom line: enjoy cannabis responsibly, but keep it away from your animals. A locked drawer or high shelf can prevent a $2,000 emergency vet bill.
