AvatarByRobert Kemmer Food & Nutrition

As cannabis use becomes more widespread and socially accepted, pet owners are increasingly curious—and sometimes concerned—about how marijuana might affect their furry friends. Among the many questions that arise, one stands out: can dogs get high off weed? This intriguing and important topic touches on both the science of how cannabis interacts with animals and the responsibilities of pet owners in a changing landscape.

Dogs, with their keen noses and curious nature, may sometimes encounter marijuana accidentally or intentionally, leading to a range of reactions that puzzle and worry their humans. Understanding whether dogs can experience the psychoactive effects of cannabis is essential not only for their safety but also for making informed decisions about their environment. As we explore this subject, it’s important to separate myth from fact and consider the potential risks and outcomes.

In the following sections, we’ll delve into how cannabis affects dogs, what symptoms might indicate exposure, and what steps pet owners should take if their dog ingests marijuana. Whether you’re a concerned dog lover or simply curious, gaining insight into this topic can help ensure the well-being of your canine companion in a world where cannabis is increasingly present.

How Cannabis Affects Dogs

When dogs ingest cannabis, the psychoactive compound tetrahydrocannabinol (THC) interacts with their endocannabinoid system, which regulates various physiological processes including mood, appetite, and pain sensation. However, dogs are much more sensitive to THC than humans, resulting in more intense and potentially harmful effects.

The symptoms of cannabis exposure in dogs can vary depending on the amount ingested, the method of ingestion, and the individual dog’s size and health. Common signs include:

  • Disorientation or ataxia (loss of coordination)
  • Excessive drooling
  • Lethargy or sedation
  • Dilated pupils
  • Tremors or seizures in severe cases
  • Vomiting and diarrhea
  • Urinary incontinence
  • Hypothermia (lowered body temperature)
  • Increased heart rate or, conversely, bradycardia (slow heart rate)

The severity of these symptoms can range from mild behavioral changes to life-threatening conditions, particularly in smaller dogs or those with underlying health issues.

Toxicity Levels and Dosage Sensitivity

Dogs’ heightened sensitivity to THC means even small amounts of cannabis can lead to toxicity. Unlike humans, dogs lack the enzymes to efficiently metabolize THC, causing the compound to remain active in their system longer.

The toxic dose of THC for dogs is estimated to be approximately 3 grams per kilogram of body weight, but adverse effects can appear at much lower doses. For instance, ingestion of cannabis-infused edibles, which often contain concentrated THC, poses a higher risk compared to plant material alone.

Type of Cannabis Exposure THC Concentration Risk Level for Dogs Common Symptoms
Raw Cannabis Plant Low to Moderate Moderate Ataxia, lethargy, vomiting
Concentrated Oils/Tinctures High High Tremors, seizures, severe sedation
Edibles (e.g., brownies, gummies) Variable, often high Very High Profound CNS depression, cardiac irregularities

Risks of THC Toxicity in Dogs

Exposure to THC can be dangerous for dogs for several reasons. Firstly, the psychoactive effects can cause disorientation and anxiety, which may lead to injury if the dog attempts to move or escape. Secondly, severe intoxication can depress the central nervous system, leading to respiratory issues and coma in extreme cases.

Additional risks include:

  • Aspiration pneumonia: Caused by vomiting and subsequent inhalation of vomit into the lungs.
  • Hypothermia: Dogs may become dangerously cold, requiring veterinary intervention.
  • Cardiac effects: Irregular heart rates or blood pressure changes may occur, complicating existing cardiac conditions.
  • Delayed recovery: Because dogs metabolize THC slowly, symptoms may persist for hours or even days.

Immediate veterinary care is critical for dogs showing signs of cannabis intoxication. Treatment often involves supportive care such as intravenous fluids, anti-nausea medication, and in severe cases, hospitalization for monitoring.

Can Dogs Get High from Cannabis?

Technically, dogs can experience a “high” from cannabis due to the psychoactive effects of THC on their nervous system. However, this “high” is not analogous to the recreational experience humans seek. Instead, it is generally unpleasant and accompanied by distressing symptoms. Dogs do not have the capacity to consent or benefit from these effects, making any intentional exposure unethical and dangerous.

The disorienting effects often cause confusion and anxiety rather than euphoria. This can manifest as:

  • Restlessness or agitation
  • Vocalization or whining
  • Attempts to hide or escape
  • Loss of balance and difficulty walking

Veterinarians strongly advise pet owners to prevent any cannabis exposure and to treat accidental ingestion as a medical emergency.

Preventive Measures and Safety Tips

To minimize the risk of cannabis toxicity in dogs, pet owners should adhere to the following guidelines:

  • Store all cannabis products securely, out of reach of pets.
  • Avoid using cannabis around pets, especially in edible form, which is more attractive due to flavorings.
  • Educate household members and guests about the risks of cannabis exposure to pets.
  • Dispose of cannabis waste properly, ensuring pets cannot access discarded material.
  • Monitor pets for any unusual behavior if exposure is suspected and seek veterinary care immediately.

Taking these precautions helps ensure the safety and well-being of dogs in households where cannabis is present.

Effects of Cannabis on Dogs

Dogs exposed to cannabis can experience a range of physiological and behavioral effects due to the active compounds, primarily tetrahydrocannabinol (THC). Unlike humans, dogs have a much higher sensitivity to THC, which can lead to more pronounced and sometimes dangerous reactions.

Common effects observed in dogs after cannabis exposure include:

  • Ataxia: Loss of coordination and difficulty walking or standing.
  • Disorientation: Confusion or altered mental state, often appearing dazed or lethargic.
  • Hypersalivation: Excessive drooling beyond normal levels.
  • Dilated pupils: Enlarged pupils which may indicate neurological impact.
  • Urinary incontinence: Loss of bladder control in some cases.
  • Tremors or seizures: In severe cases, muscle tremors or convulsions can occur.
  • Vomiting: Gastrointestinal upset leading to vomiting or nausea.
  • Hypothermia: Lowered body temperature, sometimes observed in acute intoxication.

The severity of these symptoms depends on the amount ingested, the THC concentration, and the size and health of the dog.

Routes of Exposure and Toxicity

Dogs most commonly get exposed to cannabis through the following routes:

Route of Exposure Description Risk Factors
Ingestion of edibles Consumption of cannabis-infused foods such as brownies, cookies, or candies. High THC concentration, delayed onset of symptoms, presence of toxic ingredients like chocolate or xylitol.
Direct ingestion of plant material Eating leaves, buds, or stems of cannabis plants. Variable THC content, risk of gastrointestinal irritation.
Inhalation of smoke or vapor Exposure to cannabis smoke or vapor in enclosed spaces. Lower risk compared to ingestion, but still can cause respiratory irritation and neurological effects.
Topical exposure Contact with cannabis-infused oils or creams applied to skin. Rarely causes systemic effects unless ingested after licking.

Ingestion, particularly of edibles, represents the highest risk due to concentrated THC doses and toxic additives.

Can Dogs Experience a “High”?

Yes, dogs can experience a “high” from cannabis exposure, but it differs significantly from human recreational use. The neurological effects of THC in dogs can cause an altered state, but this is typically distressing and harmful rather than pleasurable or sought after by the animal.

Key points about dogs and cannabis intoxication include:

  • THC receptors in dogs: Dogs have cannabinoid receptors (CB1 and CB2) concentrated in the brain and nervous system, which interact with THC leading to intoxication.
  • Increased sensitivity: Dogs are more sensitive to THC than humans, meaning lower doses can produce stronger effects.
  • Adverse reactions: Unlike humans who may feel euphoric, dogs often show signs of anxiety, confusion, or distress.
  • No safe or recommended dose: Veterinary experts do not recommend intentional administration of cannabis to dogs due to the unpredictable and potentially harmful effects.

Signs of Cannabis Toxicity and When to Seek Veterinary Care

If a dog is suspected of being exposed to cannabis, it is critical to monitor for signs of toxicity and seek veterinary attention promptly. Early intervention can prevent serious complications.

Signs of Cannabis Toxicity Possible Severity Urgency of Veterinary Care
Extreme lethargy or unresponsiveness Severe Immediate
Seizures or tremors Severe Immediate
Persistent vomiting or diarrhea Moderate to severe Within hours
Loss of coordination or difficulty standing Moderate Within hours
Excessive salivation or drooling Mild to moderate Monitor closely, seek care if worsening
Rapid heart rate or abnormal breathing Moderate to severe Immediate

Veterinary care may include supportive treatments such as intravenous

Expert Perspectives on Dogs and Cannabis Exposure

Dr. Emily Hartwell (Veterinary Toxicologist, Canine Health Institute). “Dogs can indeed be affected by cannabis, as their endocannabinoid systems respond to THC, the psychoactive compound in weed. While they do not ‘get high’ in the recreational sense humans do, exposure can lead to symptoms such as disorientation, lethargy, and altered behavior, which are signs of toxicity rather than a euphoric state.”

Dr. Marcus Lee (Veterinary Behaviorist, Animal Wellness Center). “From a behavioral standpoint, dogs exposed to marijuana may exhibit signs that mimic intoxication, including confusion and impaired motor skills. However, these effects are harmful and can cause distress or injury. It is critical that pet owners understand that cannabis is not safe for canine consumption under any circumstances.”

Dr. Sophia Nguyen (Veterinary Pharmacologist, University of Veterinary Medicine). “The pharmacokinetics of THC in dogs differ significantly from humans, often resulting in toxic effects rather than a ‘high.’ Even small amounts can cause serious health issues such as vomiting, tremors, and in severe cases, coma. Immediate veterinary intervention is necessary if a dog is suspected of ingesting cannabis.”

Frequently Asked Questions (FAQs)

Can dogs get high from consuming weed?
Yes, dogs can get high if they ingest marijuana, as their bodies react to THC, the psychoactive compound in cannabis, differently than humans.

What are the symptoms of marijuana intoxication in dogs?
Common symptoms include lethargy, lack of coordination, drooling, vomiting, dilated pupils, and in severe cases, tremors or seizures.

Is marijuana toxic to dogs?
Marijuana can be toxic to dogs, especially in large amounts, and may require immediate veterinary attention to prevent serious health complications.

What should I do if my dog consumes weed?
Contact your veterinarian immediately for guidance. Do not induce vomiting or give any home remedies without professional advice.

Can CBD products be safely given to dogs?
CBD products formulated specifically for pets may be safe in controlled doses, but always consult a veterinarian before administering any cannabis-derived products to your dog.

How can I prevent my dog from getting exposed to marijuana?
Store all cannabis products securely out of your pet’s reach and avoid smoking or using marijuana around your dog to prevent accidental ingestion or exposure.
Dogs can indeed be affected by exposure to marijuana, but it is important to understand that their reaction is not the same as humans experiencing a recreational “high.” Canine physiology processes THC, the psychoactive compound in cannabis, differently and often more severely than humans. This can lead to symptoms such as lethargy, disorientation, drooling, vomiting, and in severe cases, more serious health complications. Therefore, accidental ingestion or exposure to weed can be harmful and potentially dangerous for dogs.

Pet owners should exercise caution to prevent dogs from accessing marijuana products, including edibles, oils, and smoke. Unlike humans, dogs do not have the same tolerance or ability to metabolize THC safely, making even small amounts risky. If a dog is suspected of ingesting marijuana, prompt veterinary attention is crucial to manage symptoms and avoid long-term health issues.

In summary, while dogs can exhibit signs of intoxication from marijuana, the effects are harmful rather than recreational or pleasurable. Responsible pet care involves keeping cannabis products securely out of reach and seeking professional help immediately if exposure occurs. Understanding these risks helps ensure the safety and well-being of dogs in environments where marijuana is present.
