If your dog eats weed, treat it as an emergency and act quickly and calmly. In most cases dogs survive, but they can get very sick and sometimes life‑threatening complications occur, especially with edibles.

What to Do If Your Dog Eats Weed

First: Quick Action Steps

Do these immediately:

  1. Stay calm and secure your dog
    • Move them to a quiet, safe area so they don’t fall down stairs, wander outside, or injure themselves.
    • Keep other pets and kids away.
  2. Stop access to more weed
    • Remove any remaining weed, edibles, gummies, vapes, or roaches.
    • Check the floor, couch, trash, car, and backyard if that’s where it happened.
  3. Call a vet or pet poison helpline now
    • Call your regular vet, an emergency vet, or an animal poison hotline.
    • Be honest: say clearly, “My dog ate weed” and, if applicable, what kind (bud, edible, vape oil, resin, etc.).
  4. Do NOT make your dog vomit on your own
    • Don’t use hydrogen peroxide, salt, or home remedies unless a vet specifically tells you to.
    • A stoned dog can choke or aspirate vomit into their lungs.
  5. If they seem very unsteady or non‑responsive, go in person
    • If they are collapsing, can’t stand, are very out of it, or have seizure‑like movements, go to the nearest emergency vet right away.

What Your Vet Will Want to Know

Having details ready helps your dog get the right care faster:

  • What your dog ate
    • Loose flower, joint, blunt, vape cartridge, gummy, brownie, butter/oil, “dab,” capsule, tincture, etc.
  • Approximate amount
    • Rough grams, number of gummies, “half a brownie,” “one pre‑roll,” etc.
  • THC content if known
    • Label from the package (e.g., 10 mg THC per gummy, 80% THC vape).
  • Other ingredients
    • Chocolate, xylitol, raisins, caffeine, alcohol, other drugs or meds mixed in.
  • Your dog’s basics
    • Weight, age, known health problems (heart disease, kidney issues, epilepsy, etc.).
  • Time since ingestion
    • “Just now,” 30–60 minutes ago, a few hours ago, not sure but noticed symptoms starting at X time.

Transparency matters: vets are not there to report you; they’re there to treat your dog safely.

Signs Your Dog May Be High or Intoxicated

Symptoms can appear within 30 minutes to a few hours and vary from mild to severe. Common signs:

  • Very wobbly or “drunk” walk, stumbling, falling over
  • Acting disoriented or spaced out, staring, slow responses
  • Dilated pupils, glassy or bloodshot eyes
  • Drooling, sometimes vomiting
  • Sudden sound sensitivity (startling easily)
  • Whining, restlessness, anxiety, or clinginess
  • Deep sleep, hard to wake, but still breathing steadily

More serious signs (emergency):

  • Very low or very high heart rate
  • Low body temperature (cold ears/paws, shivering)
  • Incontinence (peeing or pooping without awareness)
  • Rigid muscles, tremors, twitching, or seizures
  • Very slow or very shallow breathing
  • Unresponsiveness or coma‑like state

If you see anything from the “serious” list, go to an emergency vet immediately.

Home vs Vet: How to Decide

You always at least call a professional, but here’s how situations usually break down:

Likely needs an emergency vet visit

  • Small dog ate high‑dose edibles (multiple gummies, brownies, candy).
  • Any dog ate weed plus :
    • Chocolate
    • Xylitol (often in sugar‑free candies/gums)
    • Raisins or grapes
    • Other drugs (opioids, benzos, MDMA, cocaine, etc.).
  • Dog is:
    • Collapsing or can’t stand
    • Barely responsive or very confused
    • Having tremors or seizures
    • Vomiting repeatedly
    • Breathing oddly or has bluish gums/tongue

May be monitored at home (only if a vet says so)

  • You’ve spoken to a vet or poison service and they’ve reviewed:
    • Dog’s weight
    • Estimated dose
    • Symptoms (mild and stable)
  • Dog is:
    • Aware of surroundings
    • Able to walk (even if wobbly) and swallow safely
    • Breathing normally
    • Not showing signs of distress or severe confusion

In those mild cases, a vet may advise “supportive home care” and monitoring instead of a hospital stay.

What NOT to Do

Even if online forums or friends suggest it, avoid these:

  • Don’t try to “sober them up” with other substances
    • No alcohol, coffee, energy drinks, CBD, or other drugs.
  • Don’t force food or water
    • An uncoordinated dog can choke; offer small amounts if they’re able and willing to swallow normally.
  • Don’t wait and see with severe signs
    • “Sleeping it off” is only safe in mild, vet‑approved cases.
  • Don’t lie or hide the weed factor
    • If you say, “I don’t know what happened,” vets must take longer to rule out other conditions (like stroke, meningitis, trauma), delaying targeted care.

What Treatment at the Vet May Look Like

Treatment focuses on safety and helping the drug pass through their system. Depending on timing and severity, a vet may:

  • Induce vomiting (only if it’s very soon after ingestion and the dog is still alert and coordinated).
  • Give activated charcoal to bind THC in the gut and reduce absorption.
  • Start IV fluids to help maintain blood pressure, hydration, and help the body clear the drug.
  • Provide temperature support with warming or cooling, depending on whether the dog is too cold or too warm.
  • Give medications to control nausea, anxiety, tremors, or seizures if they occur.
  • Hospitalize for monitoring for 12–24+ hours until the dog is stable and more normal.

There is no “antidote” for THC; treatment is about keeping your dog safe and comfortable until it wears off.

How Long Will My Dog Be High?

This depends on:

  • Form of THC : Edibles and oils last longer than smoke exposure.
  • Dose and concentration : High‑milligram gummies or potent oil = worse and longer symptoms.
  • Size and health of your dog : Small or medically fragile dogs are affected more severely.

Common ranges people report:

  • Mild cases: a few hours of wobbliness and drowsiness.
  • Moderate cases: 12–24 hours of being out of it.
  • Severe cases or large edible doses: sometimes 24–72 hours before they are fully normal.

Your vet can give the best estimate after evaluating your dog.

Prevention: How to Keep This from Happening Again

With cannabis use increasingly common, accidental dog exposure is a trending problem. Treat weed like any other medication in the house. Practical tips:

  • Store all weed, gummies, brownies, vapes, and oils in closed cabinets or lockboxes.
  • Never leave ashtrays, roaches, or half‑smoked joints where dogs can reach them.
  • Be cautious with trash : bag and take it out if it contains any cannabis products.
  • Don’t blow smoke or vapor in your dog’s face or in a closed room with them.
  • Tell guests that nothing cannabis‑related goes on the coffee table or within nose‑level of your dog.
  • Treat infused butter or cooking oils like poison from a dog’s perspective—don’t store them in easy‑access containers.

A simple rule: if a child could accidentally eat it, so can your dog.

Forum‑Style Note: What People Often Ask

“My dog ate weed an hour ago and looks super high. Will he die?”

  • In many real‑world cases shared on forums, dogs do not die and recover fully, but the experience can be scary and very unpleasant for them.
  • The biggest dangers:
    • Very large doses,
    • Edibles with other toxic ingredients (chocolate, xylitol),
    • Complications like aspiration pneumonia from vomiting while sedated.
  • That’s why you should always talk to a vet or poison helpline and not rely on anecdotal “my dog was fine” stories.

“Can I get in legal trouble if I tell the vet?”

  • In most places, vets are focused on animal welfare, not law enforcement.
  • Not being honest risks misdiagnosis and slower, less effective treatment for your dog.

TL;DR – Quick Scoop

  • Assume any weed ingestion is serious enough to warrant at least a phone call to a vet.
  • Don’t try home detox tricks like forced vomiting, coffee, or alcohol.
  • Go straight to an emergency vet if your dog is very wobbly, unresponsive, having tremors, or ate high‑dose edibles or weed mixed with chocolate/xylitol.
  • For mild cases where a vet says home monitoring is okay, keep your dog warm, safe, quiet, and watched constantly until they are themselves again.
  • Prevention (secure storage, careful trash, and no table‑top edibles) is the only way to guarantee this doesn’t happen twice.
