Can Dogs Eat Cannabis? The Short Answer

No. Cannabis is toxic to dogs.

Whether it’s raw marijuana leaves, a THC-infused cookie, or a dab of concentrate, cannabis contains tetrahydrocannabinol (THC)—the psychoactive compound that produces a “high” in humans. Dogs are far more sensitive to THC than we are, and even small amounts can cause severe illness, organ damage, or death.

This includes all forms of cannabis: recreational marijuana, medical cannabis, and even some “hemp-derived” products if they contain THC. The bottom line? Keep all cannabis products far out of your dog’s reach, and never intentionally feed them to your pet.

Understanding Cannabis and Dogs: What You Need to Know

To grasp why cannabis is dangerous for dogs, let’s start with the science. Cannabis plants (Cannabis sativa) contain over 100 cannabinoids, the most well-known being THC and cannabidiol (CBD). While humans have a well-developed endocannabinoid system (ECS) that regulates mood, pain, and appetite, a dog’s ECS is more sensitive—especially to THC.

When a dog ingests THC, it binds to cannabinoid receptors in their brain and central nervous system, disrupting normal function. This leads to a range of symptoms, from mild disorientation to life-threatening seizures.

Key Terms to Know:

  • THC (Tetrahydrocannabinol): The psychoactive compound in cannabis that’s toxic to dogs. Concentrations vary by product: flower (marijuana buds) typically has 5-30% THC, edibles can have 10-100mg per serving, and concentrates (wax, shatter) may have 60-90% THC.
  • CBD (Cannabidiol): A non-psychoactive cannabinoid often marketed for its calming or anti-inflammatory effects. While CBD itself is not toxic, many CBD products (especially unregulated ones) may contain trace amounts of THC, which is toxic.
  • Hemp vs. Marijuana: Hemp is a variety of Cannabis sativa with <0.3% THC (federal legal limit in the U.S.). Marijuana has higher THC levels. However, “hemp” products like oils or treats may still contain THC if not properly processed, so they’re not automatically safe.

The Risks of Cannabis for Dogs (Why Even Small Amounts Matter)

THC toxicity in dogs is no joke. The severity of symptoms depends on:

  • Your dog’s size (smaller dogs are more vulnerable).
  • The amount of THC ingested.
  • The form of cannabis (edibles, concentrates, etc.—edibles often have added toxins like chocolate or xylitol).

Common Symptoms of Cannabis Toxicity in Dogs:

  • Lethargy or depression (your dog may seem “drunk” or unresponsive).
  • Incoordination (stumbling, difficulty walking, head bobbing).
  • Vomiting or diarrhea (may be bloody in severe cases).
  • Increased heart rate or drooling.
  • Dilated pupils or glassy eyes.
  • Tremors, seizures, or muscle twitching.
  • Urinary incontinence (inability to control bladder).
  • Coma or death (in extreme cases, especially with high-THC products).

Additional Dangers in Edibles:

Many cannabis edibles (brownies, gummies, cookies) contain ingredients that are extra toxic to dogs:

  • Chocolate: Contains theobromine, which is poisonous to dogs.
  • Xylitol: A sugar substitute that causes rapid insulin release, leading to hypoglycemia (low blood sugar), liver failure, or death.
  • Artificial sweeteners/flavors: May contain other harmful additives.

Even a single THC-infused gummy can be deadly for a small dog. If you suspect your dog has eaten any cannabis product—edible or not—contact your vet or an animal poison control center immediately.

Potential Benefits: Separating Fact from Fiction

You may have heard claims that cannabis (or CBD) can help dogs with anxiety, pain, or seizures. Let’s set the record straight:

Myth: “Cannabis has nutrients like fiber or potassium that are good for dogs.”

False. Cannabis leaves, buds, or stems are not a source of meaningful nutrients for dogs. They’re low in fiber, protein, or vitamins, and any potential “benefit” is far outweighed by the risk of THC toxicity.

Myth: “CBD oil cures my dog’s anxiety/pain.”

Maybe, but proceed with extreme caution. CBD itself is not toxic to dogs, and some studies suggest it may have anti-inflammatory or calming effects. However:

  • THC is the danger. Many CBD products (especially unregulated ones) contain trace THC, which can poison your dog.
  • Not all CBD is created equal. Only use CBD products specifically formulated for pets (look for “THC-free” and third-party tested), and only under the guidance of your vet. The FDA has not approved CBD for dogs, so claims about its benefits are largely anecdotal.

How Much Cannabis Is Safe for Dogs? The Honest Truth

None. There is no “safe” amount of cannabis for dogs. Even a tiny dose can cause harm.

For example:

  • A 10mg THC edible could sicken a 10-pound dog.
  • A few bites of a marijuana brownie (with chocolate) could kill a small breed.
  • Concentrates (wax, oil) are highly potent—even a drop can be fatal.

THC affects dogs differently than humans, and there’s no way to “dose” it safely. The only responsible choice is to keep all cannabis products away from your pet.

Healthier Alternatives to Cannabis for Your Dog

If you’re looking to help your dog with anxiety, pain, or other issues, there are safer, vet-approved alternatives:

For Anxiety:

  • Exercise: A tired dog is a calm dog! Daily walks, playtime, or puzzle toys reduce stress.
  • L-theanine: A natural amino acid (found in green tea) that promotes relaxation. Look for vet-recommended supplements.
  • Chamomile: A small amount of plain chamomile tea (cooled) can soothe mild anxiety (check with your vet first).
  • ThunderShirts: Compression garments that provide a calming “hug” during storms or fireworks.

For Pain/Inflammation:

  • Turmeric: A natural anti-inflammatory (mix a pinch with food, but check with your vet for dosage).
  • Omega-3 fatty acids: Found in fish oil (vet-approved brands) to support joint health.
  • Prescription meds: Non-steroidal anti-inflammatories (NSAIDs) like carprofen, prescribed by your vet for chronic pain.

For Seizures:

  • Vet-prescribed anticonvulsants: Medications like phenobarbital or potassium bromide are proven to manage seizures safely.
  • Diet: Some dogs benefit from a low-carb, high-fat diet (keto) under veterinary supervision.

FAQ: Your Cannabis and Dog Questions Answered

Q: My dog ate cannabis—what should I do?

A: Act fast! Call your vet or the ASPCA Animal Poison Control Center (APCC) at (888) 426-4435 (fee applies) or Pet Poison Helpline at (855) 764-7661 (fee applies). Provide details: your dog’s weight, the type of cannabis (edible, flower, etc.), and when ingestion happened. Do NOT induce vomiting unless told to by a vet.

Q: Is CBD oil safe for dogs?

A: It may be, but only if it’s THC-free and recommended by your vet. Look for products labeled “broad-spectrum” or “isolate” (no THC), third-party tested, and made for pets. Never use human CBD oil, as it may contain THC or other toxins.

Q: Can dogs eat hemp seeds?

A: Hemp seeds (from low-THC hemp plants) are different from cannabis. They’re a good source of protein, omega-3s, and fiber—in moderation. Check with your vet first, and start with a tiny amount (e.g., 1/4 tsp for small dogs) to avoid stomach upset.

Q: How long do cannabis toxicity symptoms last in dogs?

A: Symptoms usually appear within 30-60 minutes of ingestion and can last 12-24 hours (or longer for high doses). Severe cases may require hospitalization for IV fluids, anti-seizure meds, or supportive care.

Conclusion: Prioritizing Your Dog’s Safety

As pet parents, our top priority is keeping our furry friends happy and healthy. When it comes to cannabis, the risks are clear: THC is toxic to dogs, and even small amounts can have devastating consequences.

Keep all cannabis products—flower, edibles, oils, concentrates—locked away, out of paws’ reach. If you use CBD for your dog, work closely with your vet to choose a safe, THC-free product. And if ingestion happens, don’t wait—call for help immediately.

Your dog relies on you to protect them. By staying informed and vigilant, you’re giving them the best chance at a long, healthy life.

Stay safe, and give your pup an extra treat (the dog-friendly kind!) today.
