Can Dogs Get High Off Weed? What Every Pet Owner Should Know

AvatarByWilliam Warren Food & Nutrition

As cannabis use becomes more widespread and socially accepted, many pet owners find themselves wondering about the effects of marijuana on their furry companions. One common question that arises is: can dogs get high off weed? This curiosity is not just casual—understanding how cannabis interacts with dogs is crucial for responsible pet care and safety.

Dogs have a very different physiology from humans, which means substances like THC, the psychoactive component in marijuana, can affect them in unique and sometimes dangerous ways. While some pet owners might be concerned about accidental exposure, others are interested in the potential therapeutic uses of cannabis for dogs. Regardless of the angle, it’s important to explore how and why dogs might experience the effects of weed, and what that means for their health and well-being.

In the following sections, we will delve into how cannabis impacts dogs, the risks involved, and what precautions pet owners should take. Whether you’re a curious dog lover or someone seeking to protect your pet, gaining a clear understanding of this topic is essential in today’s evolving landscape of cannabis use.

Effects of THC on Dogs

When dogs are exposed to THC (tetrahydrocannabinol), the primary psychoactive compound in cannabis, their reaction differs significantly from humans. Dogs have a higher concentration of cannabinoid receptors, particularly CB1 receptors, in their brains, which makes them more sensitive to THC. This sensitivity can result in a range of neurological and physiological effects that may be unpleasant or even dangerous for the animal.

Common signs of THC intoxication in dogs include:

  • Disorientation or uncoordinated movements (ataxia)
  • Excessive drooling
  • Dilated pupils
  • Vocalization, including whining or barking
  • Increased heart rate (tachycardia) or, less commonly, slow heart rate
  • Urinary incontinence
  • Vomiting or diarrhea
  • Lethargy or sedation
  • Tremors or seizures in severe cases

Because dogs metabolize THC differently, even small amounts can lead to pronounced effects, and symptoms may last several hours. It is important to recognize these signs early and seek veterinary care if necessary.

Toxicity Levels and Risk Factors

The toxicity of THC in dogs depends on several factors, including the amount ingested, the potency of the cannabis product, the dog’s size, and its overall health. Edibles pose a particular risk because they often contain high concentrations of THC and other ingredients like chocolate or xylitol, which are also toxic to dogs.

Factor Impact on THC Toxicity
Dog’s Weight Smaller dogs are more susceptible to severe effects from lower doses.
THC Dose Higher doses increase the risk of severe symptoms and complications.
Product Type Edibles and concentrates have higher THC levels and often additional toxins.
Health Status Dogs with pre-existing conditions may have worsened symptoms.
Route of Exposure Oral ingestion leads to delayed but prolonged effects compared to inhalation.

The minimum toxic dose is not definitively established but is estimated to be around 3 mg/kg of THC in dogs. However, dogs can exhibit symptoms at lower doses, so any exposure should be taken seriously.

Why Dogs Cannot Safely Get High

Unlike humans who may choose to consume cannabis recreationally or medicinally, dogs cannot safely experience the “high” associated with THC. The adverse effects overshadow any psychoactive sensation due to the following reasons:

  • Increased Sensitivity: Dogs’ nervous systems react more intensely to THC, often resulting in distress rather than euphoria.
  • Lack of Voluntary Use: Dogs do not self-administer cannabis, so exposure is accidental and typically involves inappropriate dosing.
  • Potential for Toxicity: Even low doses can cause toxic reactions, including neurological impairment and cardiovascular effects.
  • No Therapeutic Benefit: Unlike CBD, which has some veterinary research support, THC has no proven safe therapeutic use in dogs.

Veterinarians strongly advise against exposing dogs to cannabis or products containing THC. Instead, pet owners should focus on safe, veterinary-approved treatments for any medical conditions.

Emergency Response and Treatment

If a dog is suspected of ingesting cannabis, immediate veterinary attention is critical. Early intervention can reduce the severity of symptoms and prevent complications.

Key steps include:

  • Removing Access: Secure the environment to prevent further ingestion.
  • Monitoring Symptoms: Watch for signs like ataxia, vomiting, or seizures.
  • Inducing Vomiting: If ingestion occurred recently, a vet may induce vomiting to reduce absorption.
  • Activated Charcoal: Administered to limit THC absorption in the gastrointestinal tract.
  • Supportive Care: Intravenous fluids, oxygen therapy, and temperature regulation may be necessary.
  • Medications: In some cases, anticonvulsants or sedatives are used to control tremors or agitation.

Owners should never attempt to treat cannabis toxicity at home without professional guidance, as improper care can worsen the condition.

Differences Between THC and CBD in Dogs

It is important to distinguish THC from CBD (cannabidiol), another compound found in cannabis. Unlike THC, CBD is non-psychoactive and has gained popularity as a potential therapeutic agent for dogs, used to manage anxiety, pain, and inflammation.

Characteristic THC CBD
Psychoactive Effects Yes, causes intoxication and impairment No, does not cause a “high”
Toxicity Risk High, especially in small doses Low, generally well tolerated
Veterinary Use Not recommended Increasingly used under vet supervision
Legal Status Controlled substance in many areas More widely legal and accessible

Owners considering CBD for their pets should consult with a veterinarian to ensure proper dosing, quality, and safety.

Can Dogs Get High Off Weed?

Dogs can indeed experience the psychoactive effects of cannabis if they ingest or inhale it. The primary compound responsible for the “high” in cannabis is tetrahydrocannabinol (THC), which interacts with the endocannabinoid system present in dogs as well as humans. However, dogs are much more sensitive to THC, and even small amounts can lead to significant intoxication.

The effects of THC on dogs can vary widely depending on factors such as the dose, method of exposure, and the dog’s size and overall health. It is important to understand the symptoms of cannabis intoxication in dogs and the potential risks involved.

How Dogs Are Affected by THC

When a dog is exposed to THC, the compound binds to cannabinoid receptors in the brain and nervous system, causing neurological and behavioral changes. Unlike humans, dogs metabolize THC differently, often leading to more severe effects at lower doses.

Factor Impact on THC Effects in Dogs
Size and Weight Smaller dogs are more susceptible to toxicity due to lower body mass.
Form of Cannabis Edibles (especially with chocolate or xylitol) are more dangerous than raw plant material.
Concentration of THC Higher THC concentration leads to increased severity of symptoms.
Method of Exposure Ingestion causes longer-lasting effects than inhalation.

Signs of Cannabis Intoxication in Dogs

Exposure to THC can cause a range of symptoms in dogs, some of which require immediate veterinary attention. Recognizing these signs can help pet owners respond quickly and minimize harm.

  • Ataxia: Loss of coordination or unsteady gait.
  • Dilated pupils: Larger than normal pupils, sometimes unresponsive to light.
  • Excessive drooling: Increased salivation or foaming at the mouth.
  • Vomiting and diarrhea: Gastrointestinal upset is common.
  • Depression or lethargy: Reduced activity and responsiveness.
  • Disorientation or agitation: Confusion or unusual vocalizations.
  • Tremors or seizures: Severe neurological symptoms in some cases.
  • Elevated heart rate: Tachycardia may occur.

Risks and Potential Complications

While cannabis intoxication is rarely fatal, it can be dangerous and sometimes requires emergency care. Particular risks include:

  • Secondary poisoning: Edibles may contain other toxic substances such as chocolate or artificial sweeteners.
  • Respiratory distress: Inhaled cannabis smoke may cause breathing difficulties.
  • Prolonged sedation: Extended lethargy can increase the risk of aspiration pneumonia.
  • Injury: Ataxia and disorientation increase the risk of trauma from falls or accidents.
  • Underlying health conditions: Dogs with pre-existing cardiac, liver, or kidney issues may experience worsened outcomes.

What to Do If Your Dog Is Exposed

If you suspect your dog has ingested or inhaled cannabis, it is critical to take prompt action. Steps include:

  • Contact a veterinarian immediately: Early intervention can prevent complications.
  • Provide information: Be prepared to describe the type of cannabis, amount ingested, time since exposure, and symptoms observed.
  • Do not induce vomiting without veterinary guidance: Vomiting may cause aspiration or worsen symptoms depending on the dog’s condition.
  • Keep your dog calm and in a safe, quiet environment: Minimize stimulation to reduce agitation.
  • Follow veterinary advice: Treatment may include activated charcoal, intravenous fluids, anti-nausea medications, and supportive care.

Preventing Cannabis Exposure in Dogs

Prevention is the best approach to avoid accidental cannabis intoxication in dogs. Recommendations include:

  • Store cannabis products securely out of reach of pets.
  • Avoid using cannabis around pets, especially smoking indoors.
  • Dispose of cannabis edibles carefully to prevent ingestion.
  • Educate family members and visitors about the risks of cannabis exposure to pets.
  • Be aware of the signs of intoxication to act promptly if exposure occurs.
