If your dog ate weed, you’re not alone—this is a growing concern among pet owners as cannabis becomes more accessible. While marijuana can have medicinal benefits for humans, it can be dangerous for dogs. Understanding the symptoms, risks, and treatment options is crucial for ensuring your pet's well-being.

Symptoms of Marijuana Toxicity in Dogs

When a dog ingests cannabis, the active ingredient, THC (tetrahydrocannabinol), affects their nervous system. Symptoms can appear within 30 minutes to a few hours and may include:

  • Lethargy or extreme drowsiness
  • Loss of coordination (wobbly walking)
  • Vomiting
  • Drooling excessively
  • Dilated pupils or glassy eyes
  • Urinary incontinence
  • Increased heart rate or abnormal breathing
  • Sensitivity to sound and light
  • Tremors or seizures (in severe cases)

How Dangerous Is Weed for Dogs?

While marijuana toxicity is rarely fatal, it can cause significant distress and health risks. The severity depends on:

  • The amount ingested
  • The dog’s size and weight
  • The potency of the cannabis product (edibles, oils, or raw plant material)
  • Whether it was combined with chocolate, xylitol, or other toxic ingredients

What to Do If Your Dog Ate Weed

If you suspect your dog has ingested marijuana, take the following steps:

  1. Stay Calm – Panicking won’t help your pet, and clear thinking is essential.
  2. Check for Symptoms – Monitor your dog for the signs listed above.
  3. Contact a Vet Immediately – Call your veterinarian or a 24/7 emergency pet helpline.
  4. Be Honest About Exposure – Inform the vet about what your dog ate, including the type and amount of cannabis.
  5. Avoid Home Remedies – Inducing vomiting at home can be dangerous. Only do so if instructed by a vet.
  6. Provide Comfort and Hydration – Keep your dog in a quiet, comfortable place with fresh water available.

Veterinary Treatment for Weed Toxicity

Depending on the severity, your veterinarian may:

  • Induce vomiting (if ingestion was recent and safe to do so)
  • Administer activated charcoal to absorb THC
  • Provide IV fluids to help flush out toxins
  • Monitor vital signs and support breathing if necessary

How Long Does Weed Stay in a Dog’s System?

Most dogs recover within 24 to 48 hours, but effects can last longer if a large amount was consumed. The duration depends on the dose, potency, and individual metabolism.

Preventing Marijuana Toxicity in Dogs

To keep your pet safe:

  • Store Cannabis Products Securely – Keep all weed products out of reach.
  • Avoid Secondhand Smoke – Even passive exposure can affect dogs.
  • Be Mindful of Edibles – THC-infused treats often contain chocolate or xylitol, which are toxic to dogs.
  • Educate Household Members and Guests – Ensure everyone knows not to leave cannabis products accessible to pets.

When to Seek Emergency Help

Seek immediate veterinary care if your dog:

  • Has difficulty breathing
  • Is unresponsive or in a coma-like state
  • Experiences seizures
  • Shows severe vomiting or diarrhea

Conclusion

If your dog ate weed, quick action and professional veterinary care are essential. While marijuana toxicity is usually not fatal, it can be distressing for both the dog and the owner. Prevention is key—store cannabis securely, educate those around you, and always be prepared to seek medical attention if needed.
