As cannabis use becomes more common, many dog owners are asking a surprising but serious question: Can dogs get high? Whether from secondhand smoke or accidental ingestion, this issue is more common than you might think—and the consequences can be dangerous.
In this post, we’ll explore how marijuana affects dogs, what symptoms to watch for, and what to do if your dog ate weed or got high from secondhand smoke.
Can Dogs Really Get High?
Yes, dogs can get high, but not in the same way humans do. Dogs have more cannabinoid receptors in their brains than humans, making them much more sensitive to THC—the psychoactive compound in marijuana. Even a small amount can lead to marijuana toxicity in dogs, a potentially life-threatening condition.
🩺 According to Lucas Bennett, a veterinary expert with 10 years of experience, “THC toxicity in dogs is a real concern. It’s never safe or funny—it’s a medical emergency.”
What Happens If a Dog Ingests Weed?
If your dog ate weed, whether it’s dried flower, an edible, or an oil-based product, the THC is absorbed through their digestive system. Effects can start within 30 minutes to 1 hour and may last up to 24 hours or more.
Some edibles—especially those with chocolate or xylitol—pose an even greater risk.
What Are the Signs of THC Toxicity in Dogs?
If your dog is high or suffering from marijuana toxicity, symptoms can vary depending on their size, breed, and how much THC they were exposed to.
Here are the most common signs of THC toxicity in dogs:
- Lack of coordination (stumbling or swaying)
- Dilated pupils or glassy eyes
- Lethargy or extreme sleepiness
- Whining or vocalizing more than usual
- Hypersensitivity to touch or sound
- Disorientation or confusion
- Drooling and vomiting
- Tremors, twitching, or seizures
- Involuntary urination or defecation
- Slow heart rate or low body temperature
These symptoms can appear within 30–90 minutes and may last up to 72 hours. If your dog is displaying these signs, they may have been exposed to THC and need medical evaluation immediately.
What Is the Treatment for THC Toxicity in Dogs?
If your dog ate weed, or is showing signs of cannabis exposure, here’s how veterinarians treat THC toxicity in dogs:
- Stabilization & Monitoring
Vets will first stabilize your dog’s breathing, heart rate, and temperature. Oxygen and IV fluids may be administered.
- Induced Vomiting (If Caught Early)
If ingestion occurred within the past hour and the dog is alert, the vet might induce vomiting or give activated charcoal to absorb THC.
- Supportive Care
There’s no direct antidote for THC, so care includes:
- IV fluids to flush out toxins
- Temperature regulation
- Sedation if the dog is agitated or having tremors
Most dogs recover within 24–72 hours with proper care, but some severe cases require hospitalization.
🩺 Lucas Bennett, DVM, emphasizes: “Fast action can mean the difference between a scary episode and a life-threatening emergency. If your dog ate weed—don’t wait. Call a vet immediately.”
Medical Marijuana and Dogs
You may wonder: “If medical marijuana helps people, can it help my dog?”
The short answer is no—not with THC.
While cannabis has benefits for humans, THC (tetrahydrocannabinol) is toxic to dogs. However, research is ongoing on the use of CBD for dogs, which is non-psychoactive and may offer some therapeutic benefits.
Important distinctions:
- Medical marijuana (with THC): Toxic to dogs.
- CBD-only pet products (THC-free): May be safe if vet-approved.
Only consider CBD pet products that are:
- Specifically made for dogs
- THC-free (broad-spectrum or isolate)
- Third-party lab tested
- Recommended by your veterinarian
How Can I Protect Against THC Toxicity in Dogs?
Preventing marijuana exposure is the safest and most effective approach. Here’s how to protect your pup:
🧠 Safe Storage
- Keep cannabis products (flower, edibles, oils, vapes) in sealed, dog-proof containers.
- Store them in cabinets or drawers far from pet access.
🚭 Avoid Secondhand Smoke
- Can dogs get high from secondhand smoke? Yes—and it can cause harm.
- Never smoke cannabis near your dog, especially indoors or in cars.
🍫 Watch Edibles
- Many THC edibles contain chocolate, xylitol, or other harmful ingredients.
- Never leave baked goods, gummies, or infused snacks unattended.
👥 Educate Others
- Inform friends, family, and guests about keeping marijuana away from pets.
🗑️ Dispose of Waste Properly
- Dogs may dig through trash. Securely discard joints, roaches, and packaging.
Can Dogs Get High From Secondhand Smoke?
Yes, dogs can get high from secondhand smoke, especially in confined or poorly ventilated areas. Because dogs have smaller lungs and a more sensitive respiratory system, even brief exposure can result in symptoms of THC poisoning.
If you smoke cannabis, never do it near your pet, and always ensure proper ventilation or step outside.
Dog Ate Weed: What to Do Immediately
If your dog ate weed, here’s what you should do:
- Don’t panic – Stay calm to avoid stressing your pet.
- Call your vet or emergency clinic right away.
- Provide details: what was consumed, how much, and when.
- Do not induce vomiting unless told to by a vet.
- Monitor your dog and keep them in a safe, quiet environment.
⚠️ Even if your dog seems fine, always consult a vet. THC can build up and cause worsening symptoms hours later.
Is It Ever Safe for Dogs to Get High?
No, it’s never safe. Some pet owners wonder if cannabis can help with anxiety or pain, but THC is toxic to dogs. The only safe option—if approved by your vet—may be CBD-only products designed specifically for pets and free from THC.
How to Prevent Marijuana Exposure in Dogs
- Store cannabis securely and out of your dog’s reach
- Avoid leaving edibles on tables or counters
- Don’t smoke in the same room as your pet
- Let visitors know to keep weed products secured
- Safely dispose of used cannabis material
Preventing accidental exposure is far easier (and safer) than emergency vet visits.
Frequently Asked Questions
Can dogs die from marijuana?
While rare, severe marijuana toxicity in dogs—especially with chocolate edibles or large doses—can be fatal if not treated promptly.

Yes. Canines can absorb THC through inhalation, and symptoms may appear even without ingesting marijuana. Always avoid exposing your dog to cannabis smoke.
Final Words
Can dogs get high? Yes, and it’s not safe. Whether from ingestion or secondhand smoke, THC can be toxic to dogs and may require emergency veterinary care. If your dog ate weed, don’t wait—call your vet immediately.
