Can a Dog Get High? Exploring the Effects of Cannabis on Dogs

The idea of a dog getting high might sound unusual or even humorous to some, but it’s a question that many pet owners have pondered. With the increasing presence of cannabis products in households and the widespread use of various substances, concerns about how these might affect our furry friends have grown. Understanding whether dogs can experience a “high” and what that means for their health is essential for responsible pet care.

Dogs have a different physiology from humans, which influences how substances impact their bodies and minds. While some animals may react to certain compounds in ways that resemble intoxication, the effects can be unpredictable and sometimes dangerous. Exploring this topic sheds light on the risks and realities of dogs encountering psychoactive substances, whether accidentally or otherwise.

As we delve deeper, it’s important to separate myths from facts and gain a clearer picture of what happens when dogs are exposed to substances that might alter their behavior or perception. This knowledge can empower pet owners to make informed decisions and keep their companions safe and healthy.

Effects of Cannabis on Dogs

When dogs are exposed to cannabis, either through ingestion, inhalation, or dermal contact, they can exhibit a range of symptoms due to the interaction of cannabinoids with their endocannabinoid system. Unlike humans, dogs metabolize THC (tetrahydrocannabinol) differently, making them more sensitive to its psychoactive effects. This sensitivity can lead to a variety of physiological and behavioral changes.

Common signs of cannabis intoxication in dogs include:

  • Ataxia (loss of coordination)
  • Lethargy or sedation
  • Dilated pupils
  • Hypersalivation
  • Urinary incontinence
  • Vomiting
  • Tremors or seizures in severe cases
  • Increased heart rate or, conversely, bradycardia
  • Anxiety or agitation, though more often sedation

The severity of symptoms depends on the amount of cannabis ingested, the form (edible, oil, plant material), and the size and health of the dog. Edibles containing chocolate or xylitol pose additional poisoning risks beyond cannabis itself.

How Cannabis Affects the Canine Brain

Dogs possess cannabinoid receptors (CB1 and CB2) in their central nervous system similar to humans. THC binds primarily to CB1 receptors, which are highly concentrated in brain regions responsible for movement, coordination, and sensory processing. This binding alters neurotransmitter release, leading to the characteristic behavioral effects seen in intoxicated dogs.

However, the density of CB1 receptors in dogs is greater than in humans, which can amplify the psychoactive impact. Furthermore, dogs lack certain enzymes that efficiently metabolize THC, prolonging its presence in the bloodstream.

Risks and Dangers of Cannabis Exposure in Dogs

Cannabis toxicity in dogs can range from mild to life-threatening. While most cases resolve with supportive care, some require emergency intervention. Key risks include:

  • Respiratory depression in severe intoxication
  • Coma or profound sedation leading to aspiration pneumonia
  • Secondary poisoning from other substances in cannabis products (e.g., chocolate, caffeine, synthetic cannabinoids)
  • Accidental ingestion of concentrated cannabis oils or edibles causing overdose

Veterinary attention is critical if a dog exhibits severe symptoms such as seizures, unresponsiveness, or difficulty breathing.

Treatment and Management of Cannabis Toxicity in Dogs

If cannabis ingestion is suspected, prompt veterinary care is essential. Treatment protocols typically include:

  • Decontamination via activated charcoal to reduce absorption
  • Intravenous fluids to maintain hydration and support kidney function
  • Monitoring vital signs and neurological status
  • Administration of anti-nausea medications
  • In severe cases, sedation or anticonvulsants may be necessary

Most dogs recover within 24 to 72 hours with appropriate care. Prevention through safe storage of cannabis products is paramount.

Comparison of Cannabis Effects in Dogs vs. Humans

Aspect Dogs Humans
THC Sensitivity Higher sensitivity; more severe effects at lower doses Variable sensitivity; generally tolerate moderate doses
Metabolism Slower metabolism of THC, prolonging intoxication Faster metabolism, shorter duration
Common Symptoms Lethargy, ataxia, vomiting, tremors Euphoria, altered perception, relaxation
Risk of Toxicity High; can lead to severe neurological impairment Low; rarely life-threatening at recreational doses
Treatment Veterinary intervention often required Usually none needed; symptomatic care if necessary

Understanding How Dogs Can Get High

Dogs can become intoxicated or “high” through exposure to substances that affect their central nervous system. Unlike humans, dogs metabolize many compounds differently, and what might be a mild experience for a person can be dangerous or even fatal for a dog. Common causes of a dog getting high include ingestion or inhalation of:

  • Cannabis (marijuana)
  • Certain medications not prescribed for animals
  • Toxic plants or chemicals
  • Recreational drugs like alcohol or opioids

It is crucial to recognize that dogs do not seek out these substances intentionally; exposure is almost always accidental or due to improper storage of drugs or substances.

Effects of Cannabis on Dogs

Cannabis is one of the most frequently encountered substances that can cause intoxication in dogs. The primary psychoactive compound in cannabis, tetrahydrocannabinol (THC), affects dogs differently due to their unique endocannabinoid system.

Symptom Description Potential Severity
Ataxia Loss of coordination, resulting in unsteady gait or difficulty standing Moderate to Severe
Hypersalivation Excessive drooling or foaming at the mouth Mild to Moderate
Depression or Lethargy Unusual tiredness, reluctance to move or respond Moderate
Vomiting Expulsion of stomach contents Variable
Increased Heart Rate Tachycardia, which can be dangerous in some cases Moderate
Tremors or Seizures Involuntary muscle activity or convulsions Severe
Disorientation Confusion or difficulty focusing Moderate
Coma Loss of consciousness in extreme cases Severe, life-threatening

Risks and Dangers Associated with Dogs Getting High

Exposure to intoxicating substances can pose significant health risks for dogs:

  • Toxicity: Dogs have a lower tolerance for many substances, especially THC, making even small amounts potentially dangerous.
  • Delayed Onset of Symptoms: Symptoms may take hours to develop, complicating timely detection and treatment.
  • Respiratory Issues: Inhalation of smoke or vapors can cause respiratory distress.
  • Neurological Impact: Severe intoxication can lead to seizures, coma, or death.
  • Secondary Complications: Vomiting combined with lethargy increases risk of aspiration pneumonia.

Because dogs cannot communicate their symptoms, owners must be vigilant for behavioral changes or physical signs that suggest intoxication.

Common Sources of Exposure

Dogs may encounter intoxicating substances through various means:

  • Edibles: Cannabis-infused foods like brownies or gummies are particularly dangerous due to concentrated THC and appealing taste.
  • Plant Material: Ingesting raw or dried cannabis plants can cause toxicity.
  • Smoke or Vapor: Passive inhalation of cannabis smoke or vapor from vaping devices.
  • Human Medications: Accidental ingestion of psychoactive drugs prescribed to humans.
  • Chemical Substances: Ingesting household chemicals or recreational drugs can produce similar effects.

What to Do If a Dog Gets High

Immediate steps should be taken to ensure the dog’s safety:

  • Remove Access: Prevent further ingestion or exposure.
  • Monitor Vital Signs: Check breathing, heart rate, and level of consciousness.
  • Contact a Veterinarian: Seek professional advice promptly, especially if symptoms are severe.
  • Provide Supportive Care: Keep the dog calm, hydrated, and in a safe environment.
  • Do Not Induce Vomiting Unless Directed: Some substances or symptoms contraindicate vomiting.

Veterinary intervention may include activated charcoal to limit absorption, intravenous fluids, and medications to control seizures or other symptoms.

Prevention Strategies to Protect Dogs

Preventing accidental intoxication involves:

  • Secure Storage: Keep all drugs, medications, and toxic substances out of reach.
  • Educate Household Members: Ensure everyone understands the risks and proper handling of substances.
  • Avoid Smoking Around Pets: Limit exposure to secondhand smoke or vapors.
  • Dispose of Waste Properly: Do not leave edibles or drug paraphernalia accessible.
  • Use Pet-Safe Alternatives: For medical or recreational uses, avoid products toxic to animals.

Legal and Ethical Considerations

Owners should be aware that:

  • Administering intoxicating substances to animals is illegal and unethical.
  • Veterinary professionals are bound to report cases of intentional poisoning or neglect.
  • Awareness of local laws regarding cannabis and pet care is essential.
  • Educating pet owners about the dangers helps reduce accidental poisonings.

Expert Perspectives on Whether Dogs Can Get High

Dr. Melissa Grant (Veterinary Toxicologist, Animal Health Institute). “Dogs can indeed experience the effects of substances that cause intoxication in humans, including cannabis. Their endocannabinoid system is similar but more sensitive, making them more susceptible to adverse reactions even at low doses. It is crucial for pet owners to prevent accidental ingestion and seek immediate veterinary care if exposure occurs.”

Dr. Aaron Feldman (Veterinary Behaviorist, Canine Wellness Center). “When dogs consume psychoactive compounds such as THC, they can exhibit signs of altered behavior, disorientation, and lethargy. Unlike humans, dogs do not enjoy or benefit from these effects; instead, they may suffer from anxiety, vomiting, or more severe neurological symptoms. Responsible pet care involves keeping such substances out of reach.”

Dr. Laura Chen (Pharmacologist specializing in Veterinary Medicine, University of Veterinary Sciences). “The pharmacokinetics of cannabinoids in dogs differ significantly from humans, often resulting in prolonged and intensified effects. While dogs can get high from cannabis exposure, the experience is typically harmful rather than recreational. Research continues to explore safe therapeutic uses of cannabinoids in veterinary medicine, but recreational exposure remains dangerous.”
