There is no way to instantly sober up a dog that has ingested THC. The compound has to work through your dog’s system, and that process typically takes one to two days. What you can do is keep your dog safe and comfortable during that window, recognize when the situation calls for a vet, and avoid making things worse. Most dogs recover fully without lasting effects.
Why Dogs React So Strongly to THC
Dogs have a much higher concentration of cannabinoid receptors in the back of their brain compared to humans. That means THC hits them harder, lasts longer, and produces effects that look far more alarming than what you’d expect. A dose that barely registers for a person can leave a dog visibly impaired for hours.
Signs typically start within 30 minutes to a few hours after ingestion. The most common symptoms are a wobbly, drunken walk, disorientation, lethargy, dribbling urine, a slow heart rate, and extreme sensitivity to sound and touch. Your dog may flinch at noises, startle when you pet them, or seem unable to figure out where they are. Some dogs become very still and glassy-eyed. Others get agitated or tremble.
What You Can Do at Home Right Now
Start by reducing stimulation. Move your dog to a quiet, dimly lit room away from other pets, children, and loud sounds. Their senses are dialed up, so what normally feels fine to them can be overwhelming or frightening. Speak softly and move slowly around them.
Keep your dog on a flat, padded surface close to the ground. Dogs with THC intoxication lose coordination and can fall off furniture or tumble down stairs. If your dog is dribbling urine (this is very common), lay down towels or puppy pads and change them as needed. Don’t scold them for it.
Offer water, but don’t force it. Many intoxicated dogs won’t drink, and that’s okay for the short term. If your dog is willing to sip, that helps. Monitor their body temperature by feeling their ears and paws. Dogs exposed to THC often become hypothermic, so a light blanket can help keep them warm. If they feel hot instead, remove the blanket and make sure the room isn’t stuffy.
Do not try to induce vomiting at home unless a vet specifically tells you to. Once symptoms have started, vomiting is unlikely to help and can be dangerous in a dog that’s disoriented or uncoordinated, because they could inhale vomit into their lungs.
When to Go to the Vet
Most THC exposures are uncomfortable but not life-threatening. Research in dogs found that even extremely high oral doses (thousands of milligrams per kilogram of body weight) were not lethal, and no established lethal dose exists for dogs. That said, certain situations do require professional help.
Get to a vet if your dog:
- Ate an edible containing chocolate, xylitol, or raisins. These ingredients are independently toxic to dogs. Chocolate and xylitol in particular can cause life-threatening problems that have nothing to do with the THC. If you have the packaging, bring it with you.
- Is having seizures or severe tremors. Seizures from THC alone are rare, but they happen and need medical treatment.
- Cannot stand, is unresponsive, or seems to be losing consciousness. A very lethargic dog that you can still rouse is one thing. A dog you cannot wake up needs a vet.
- Is a very small dog that ate a large amount. The smaller the dog relative to the dose, the more intense the effects.
- Has symptoms lasting beyond 72 hours. Most dogs are clearly improving by 24 to 48 hours. If your dog isn’t, something else may be going on.
Be honest with your vet about what your dog ate. They are not going to report you. Vets need accurate information because THC symptoms overlap with poisoning from many other substances. Interestingly, the standard human urine drug tests that detect THC don’t work reliably on dogs, so your vet may depend on your account to guide treatment.
What a Vet Can Do That You Can’t
Veterinary treatment for THC intoxication is supportive, meaning there’s no antidote that flips a switch and reverses the high. What a vet provides is IV fluids to prevent dehydration, temperature regulation, and medication to control agitation, tremors, or seizures if they occur. In severe cases, especially with concentrated THC products like oils or butter, vets can use a specialized fat-based IV treatment that helps the body clear THC faster, since THC binds to fat.
If the ingestion happened very recently (within the last 30 to 60 minutes) and your dog isn’t yet showing symptoms, a vet may induce vomiting or give activated charcoal to reduce how much THC gets absorbed. This is the one scenario where acting fast and calling a vet immediately makes the biggest difference.
The Recovery Timeline
Most dogs are noticeably better within 12 to 24 hours and back to normal within one to two days. More severe exposures, particularly from concentrated products like THC butter, oils, or high-dose edibles, can stretch recovery to about three days. During recovery, your dog’s coordination and appetite will gradually return. It’s common for dogs to sleep a lot during this period, which is fine as long as you can still rouse them.
Once your dog is walking steadily, eating, drinking, and urinating normally, they’ve cleared the worst of it. There are no known long-term effects from a single THC exposure in dogs.
Preventing It From Happening Again
Dogs don’t learn to avoid THC the way they might learn to avoid something that made them sick, because the intoxication itself doesn’t register as a warning the same way nausea from spoiled food would. Edibles are especially risky because they smell appealing. Store all cannabis products in sealed, dog-proof containers, ideally on a high shelf or inside a locked cabinet. This includes discarded joints, roach clips, vape cartridges, and any infused foods. If you use cannabis outdoors, be aware that dogs on walks can find discarded edibles or roaches on the ground, which is one of the most common sources of accidental exposure.
