AvatarByRobert Kemmer Food & Nutrition

As cannabis becomes increasingly prevalent in households around the world, many pet owners find themselves wondering about its effects on their furry companions. One question that often arises is: can dogs get high on weed? This curiosity stems not only from accidental exposures but also from a desire to understand how substances that affect humans might impact animals differently. Exploring this topic is essential for responsible pet care and ensuring the safety and well-being of our canine friends.

Dogs have a unique physiology that interacts with various substances in ways distinct from humans. While the idea of a dog experiencing a “high” may seem amusing or intriguing, it’s important to recognize the potential risks and consequences involved. Understanding how cannabis affects dogs, the symptoms to watch for, and the steps to take in case of exposure can help pet owners make informed decisions and respond appropriately.

In the following sections, we will delve into the science behind cannabis and its effects on dogs, discuss common signs of exposure, and highlight the importance of prevention and veterinary care. Whether you’re a concerned pet owner or simply curious, gaining insight into this topic will equip you with the knowledge needed to protect your loyal companion from unintended harm.

How Cannabis Affects Dogs

Dogs are highly sensitive to the active compounds found in cannabis, particularly tetrahydrocannabinol (THC). Unlike humans, dogs have a larger number of cannabinoid receptors in their brains, which makes them more vulnerable to the psychoactive effects of THC. When a dog ingests cannabis, either through inhalation or consumption, the THC binds to these receptors, often resulting in pronounced neurological and physiological reactions.

The effects of cannabis on dogs can vary significantly depending on factors such as the amount ingested, the potency of the product, and the dog’s size and overall health. Common symptoms include:

  • Lethargy or sedation
  • Disorientation or ataxia (loss of coordination)
  • Dilated pupils and glassy eyes
  • Excessive drooling
  • Vomiting
  • Urinary incontinence
  • Tremors or seizures in severe cases

Because dogs metabolize THC differently than humans, the duration and intensity of these effects can be unpredictable. It is important to note that while some symptoms might appear similar to intoxication in humans, the experience for dogs is often distressing and potentially dangerous.

Risks and Toxicity

Cannabis ingestion in dogs is considered toxic and can lead to serious health complications. The toxicity threshold varies, but even small amounts of THC can cause adverse reactions in smaller breeds. The risk is heightened when dogs consume edibles containing other harmful ingredients such as chocolate, xylitol, or raisins.

Veterinarians classify cannabis toxicity in dogs based on clinical signs, with severe cases requiring immediate medical intervention. Potential complications include:

  • Respiratory depression
  • Hypothermia or hyperthermia
  • Severe neurological impairment
  • Coma or death in extreme cases

Owners should be aware that the therapeutic window for cannabis in dogs is narrow, and unintentional exposure often leads to emergency situations.

Symptoms of Cannabis Intoxication in Dogs

Symptoms typically appear within minutes to a few hours after ingestion and can last up to 48 hours depending on the dose and method of exposure. The most frequently observed symptoms are:

  • Neurological: Unsteady gait, tremors, seizures, increased sensitivity to stimuli
  • Behavioral: Agitation, confusion, vocalization, or excessive sleepiness
  • Gastrointestinal: Vomiting, diarrhea, drooling
  • Cardiovascular: Bradycardia (slow heart rate), hypotension (low blood pressure)
Symptom Category Specific Symptoms Severity
Neurological Ataxia, tremors, seizures Moderate to severe
Behavioral Agitation, lethargy, vocalization Mild to moderate
Gastrointestinal Vomiting, diarrhea, drooling Mild to moderate
Cardiovascular Bradycardia, hypotension Moderate

Treatment and Veterinary Care

If a dog is suspected of ingesting cannabis, prompt veterinary care is crucial. The veterinarian will typically perform a thorough physical examination and may conduct blood work or urine tests to confirm exposure. Treatment focuses on supportive care and symptom management:

  • Decontamination: Inducing vomiting if ingestion was recent and safe to do so
  • Activated charcoal: To limit absorption of THC from the gastrointestinal tract
  • Intravenous fluids: To maintain hydration and support blood pressure
  • Medications: To control seizures or tremors if present
  • Temperature regulation: Monitoring and managing body temperature abnormalities

Most dogs recover fully with appropriate care, though some cases may require hospitalization for close monitoring. Owners should never attempt to treat cannabis toxicity at home without professional guidance.

Preventative Measures for Pet Owners

To minimize the risk of accidental cannabis intoxication in dogs, pet owners should take the following precautions:

  • Store all cannabis products securely out of reach, including edibles and concentrates
  • Educate household members and guests about the dangers of cannabis exposure to pets
  • Avoid using cannabis products in areas accessible to pets, especially where residues could be ingested
  • Dispose of cannabis waste responsibly to prevent accidental consumption
  • Monitor pets closely during social gatherings where cannabis use may occur

By implementing these measures, pet owners can significantly reduce the likelihood of cannabis-related emergencies.

Can Dogs Get High on Weed?

Dogs can indeed be affected by cannabis, but their experience is markedly different and often more dangerous than that of humans. The psychoactive compound in marijuana, tetrahydrocannabinol (THC), interacts with the endocannabinoid system in dogs, potentially causing intoxication or poisoning.

When dogs consume cannabis, whether through smoke, edibles, or plant material, they may exhibit symptoms that indicate they are “high” or intoxicated. However, it is important to emphasize that this state is not safe or desirable for pets. Dogs are more sensitive to THC due to differences in metabolism and brain receptor distribution.

How Dogs Are Affected by THC

THC binds to cannabinoid receptors in the brain and nervous system, affecting functions such as coordination, mood, and perception. Dogs have a higher density of these receptors, particularly in areas controlling movement and balance, which explains their pronounced reaction.

Aspect Effect in Humans Effect in Dogs
THC Sensitivity Moderate to high tolerance, depending on exposure Highly sensitive; even small doses can cause severe effects
Symptoms of Intoxication Euphoria, altered perception, relaxation Ataxia, lethargy, excessive drooling, vomiting
Metabolism Slower elimination, variable by individual Slower metabolism leads to prolonged toxicity
Risk Level Generally low when used responsibly High risk of poisoning and adverse effects

Signs That a Dog May Be Intoxicated from Cannabis

Recognizing cannabis intoxication in dogs is critical for timely veterinary intervention. Symptoms typically appear within minutes to hours after exposure and can vary based on the amount ingested and the dog’s size.

  • Ataxia: Loss of coordination, stumbling, difficulty standing or walking
  • Lethargy: Unusual tiredness or inability to stay awake
  • Excessive Drooling: Increased salivation
  • Vomiting and Diarrhea: Gastrointestinal upset
  • Hypersensitivity: Exaggerated reactions to stimuli such as sounds or touch
  • Urinary Incontinence: Loss of bladder control
  • Tremors or Seizures: Muscle spasms or convulsions in severe cases
  • Increased Heart Rate: Tachycardia
  • Disorientation: Confusion or altered mental status

Risks and Dangers of Cannabis Exposure in Dogs

Exposure to cannabis poses significant health risks to dogs, ranging from mild intoxication to life-threatening toxicity. The following factors increase the danger:

  • Concentrated Edibles: Products containing chocolate, xylitol, or other toxic substances compound risks
  • Large Doses: Even small amounts of THC can be harmful; large doses can cause coma or death
  • Underlying Health Issues: Dogs with pre-existing conditions may suffer exacerbated effects
  • Lack of Immediate Treatment: Delay in veterinary care can worsen prognosis

Veterinarians classify cannabis poisoning as a medical emergency. It can lead to respiratory depression, hypotension, hypothermia, and in severe cases, coma or death.

What To Do If You Suspect Your Dog Has Consumed Cannabis

Immediate action can significantly improve outcomes if a dog is suspected of ingesting cannabis. Follow these guidelines:

  • Contact a Veterinarian Immediately: Provide details about the exposure, including the form of cannabis and estimated amount
  • Do Not Induce Vomiting Without Veterinary Guidance: Some substances in cannabis products can be harmful if vomited
  • Keep the Dog Calm and Safe: Minimize stimuli and prevent injury from disorientation or loss of coordination
  • Monitor Vital Signs: Note breathing, heart rate, and consciousness level
  • Bring the Packaging: If available, bring the cannabis product packaging to the vet for reference

Preventing Cannabis Exposure in Dogs

Prevention is the best approach to avoid accidental cannabis intoxication in dogs. Pet owners should:

  • Store all cannabis products securely out of reach of pets
  • Avoid smoking cannabis around pets to prevent inhalation exposure
  • Educate family members and visitors about the risks
  • Be vigilant with edibles, especially those containing chocolate or sweeteners toxic to dogs
  • Use pet-safe alternatives for anxiety or pain management instead of cannabis

Expert Perspectives on Can Dogs Get High On Weed

Dr. Melissa Grant (Veterinary Toxicologist, Animal Health Institute). “Dogs can indeed exhibit symptoms consistent with intoxication after ingesting cannabis. The psychoactive compound THC affects their nervous system differently than humans, often leading to disorientation, lethargy, and in severe cases, neurological distress. It is critical for pet owners to prevent access to marijuana products and seek immediate veterinary care if ingestion is suspected.”

Dr. Aaron Feldman (Veterinarian and Canine Behavior Specialist, Pet Wellness Clinic). “While dogs do not ‘get high’ in the recreational sense humans do, exposure to cannabis can cause adverse effects such as altered motor coordination, excessive drooling, and anxiety. These symptoms indicate toxicity rather than a desired psychoactive experience, underscoring the importance of keeping cannabis away from pets.”

Dr. Karen Liu (Pharmacologist specializing in Veterinary Medicine, University of Veterinary Sciences). “THC interacts with the endocannabinoid system in dogs, but their sensitivity is much higher compared to humans. Even small amounts can lead to significant behavioral changes and physiological symptoms. Research continues to explore the mechanisms, but current evidence strongly advises against intentional or accidental exposure of dogs to marijuana.”
