Going Home After Marijuana Toxicity: Recovery and Prevention for Dogs

Going Home: Recovery After Marijuana Toxicity

One of my favorite parts of treating marijuana toxicity is calling owners the next day to tell them their dog is acting like themselves again.

In most cases, that's exactly what happens.

The majority of dogs recover completely with supportive veterinary care and have no long-term effects from THC exposure.

That said, it's normal to feel nervous once your dog comes home. Knowing what to expect can help you recognize what's normal during recovery—and what deserves another call to your veterinarian.

The First 24 Hours at Home

Even if your dog was discharged from the hospital, they may still be a little tired or quieter than usual.

This is completely expected.

Many dogs will:

• Sleep more than normal
• Have a mild decrease in appetite
• Walk a little slower
• Be less interested in playing
• Drink small amounts of water throughout the day

Most dogs continue improving steadily over the next several hours.

Provide a quiet, comfortable place for your dog to rest away from loud noises, excited children, or other pets.

Eating and Drinking

Unless your veterinarian has recommended otherwise, you can usually begin offering small amounts of food once your dog is fully awake and interested in eating.

Fresh water should always be available.

Some dogs are ready to eat immediately after coming home.

Others may not have much of an appetite until the following morning.

A slightly decreased appetite for the first day can be normal, but your dog's appetite should steadily improve.

Will My Dog Be Sleepy?

Probably.

THC affects the brain, and some dogs remain tired for several hours after returning home.

Your dog may:

• Nap more often
• Respond more slowly than usual
• Want extra cuddles
• Be less active

As long as they continue improving, this is generally part of the normal recovery process.

If your dog becomes more lethargic instead of gradually improving, contact your veterinarian.

When Should I Call My Veterinarian Again?

Most dogs recover without complications, but you should contact your veterinarian immediately if your dog develops:

• Repeated vomiting
• Difficulty breathing
• Seizures
• Collapse
• Inability to stand
• Pale gums
• Persistent tremors
• Refusal to eat for more than 24 hours
• Any worsening of their symptoms after they initially improved
• Trust your instincts.

You know your dog better than anyone else.

If something doesn't seem right, we'd much rather answer your questions than have you wait until your dog becomes critically ill.

Will There Be Any Lasting Effects?

Fortunately, most dogs recover completely.

Once the THC has been eliminated from the body, dogs typically return to their normal personalities, energy levels, and daily routines.

There is no evidence that a single uncomplicated marijuana exposure causes permanent brain damage in the vast majority of dogs.

However, repeated exposures should never be considered harmless.

Every intoxication carries risks, especially if your dog consumes large amounts of THC or products containing additional toxins.

Preventing It From Happening Again

Most marijuana toxicity cases are completely preventable.

Simple precautions can dramatically reduce your dog's risk.

Store Cannabis Products Like Prescription Medications

Keep all cannabis products:

• In their original containers
• Inside locked cabinets
• Out of reach of curious pets
• Away from countertops and coffee tables

Remember that dogs can chew through purses, backpacks, and plastic containers surprisingly quickly.

Be Careful With Visitors

One of the most common stories I hear is:

"I didn't even know someone had gummies in their backpack."

Friends and family members may not realize how attractive marijuana products can be to dogs.

If guests are visiting your home, remind them to keep all cannabis products securely stored.

Don't Forget Walks

Not every exposure happens at home.

Dogs occasionally find:

• Discarded joints
• Vape cartridges
• Gummies
• Edibles
• Cannabis plant material

Keeping your dog on a leash and discouraging them from picking up objects off the ground can help reduce this risk.

If Your Dog Has a History of Eating Everything...

Some dogs simply love putting inappropriate objects in their mouths.

If your dog has previously eaten socks, toys, rocks, medications, marijuana products, or other non-food items, talk with your veterinarian.

Your dog may benefit from:

• Environmental management
• Increased mental enrichment
• Additional exercise
• Training

Evaluation for underlying behavioral or medical conditions such as pica

Addressing the underlying behavior is just as important as treating the current emergency.

Frequently Asked Questions

Can my dog die from marijuana?

Most dogs recover completely with prompt veterinary care. However, severe intoxication can occur, especially with concentrated THC products or marijuana edibles containing other toxic ingredients.

My dog only ate CBD. Do I still need to call my veterinarian?

Yes.

Many products marketed as CBD contain measurable amounts of THC, and product labeling isn't always accurate.

It's safest to contact your veterinarian for guidance.

My dog seems fine. Should I still go to the veterinarian?

Yes.

Some dogs don't begin showing symptoms until several hours after ingestion.

Early evaluation gives your veterinarian the greatest number of treatment options.

Why is my dog leaking urine?

THC interferes with the nervous system's control of the bladder.

Although alarming, urinary dribbling is one of the classic signs of marijuana intoxication and usually resolves as your dog recovers.

Can secondhand marijuana smoke make my dog sick?

Heavy exposure in an enclosed space may cause problems, but ingestion of marijuana products is far more likely to result in serious toxicity.

Pets should never be intentionally exposed to marijuana smoke.

Is Delta-8 safer than Delta-9?

No.

Both products can cause significant intoxication in dogs and should be treated as potentially toxic exposures.

How long does marijuana stay in a dog's system?

Most dogs recover within 24–48 hours, although recovery may take longer after large or concentrated exposures.

Dr. Rene's Clinical Pearls

🌿 The signs of marijuana toxicity can look terrifying, but the prognosis is usually very good. Some of the sickest-looking dogs I have treated were happily wagging their tails and asking for treats the next day.

🌿 Please don't let embarrassment delay treatment. I have never judged an owner for telling me their dog got into marijuana. Honest conversations allow us to provide faster, more appropriate care.

🌿 Edibles worry me much more than marijuana alone. THC is only part of the story. Chocolate, xylitol, raisins, and other ingredients can create life-threatening emergencies of their own.

🌿 If you're not sure whether your dog got into marijuana, tell us what you suspect. You don't have to have all the answers. Even a possibility helps us make better medical decisions.

🌿 Curious dogs are going to be curious dogs. One accidental exposure doesn't make you a bad pet owner. Learn from the experience, make a few changes at home, and move forward.

The Bottom Line

Finding out your dog has eaten marijuana can be frightening, but it's important to remember that most dogs recover completely with prompt veterinary care.

The biggest mistakes I see are waiting too long to seek treatment and being afraid to tell the veterinary team what may have happened. Honest communication helps us diagnose marijuana toxicity more quickly, avoid unnecessary testing, and focus on the treatments that will help your dog recover.

If you think your dog has gotten into any THC-containing product—whether it's dried marijuana, a gummy, a brownie, a vape cartridge, or another cannabis product—don't wait for symptoms to worsen. Contact your veterinarian or the nearest emergency veterinary hospital right away.

We're here to help, not to judge, and our shared goal is getting your best friend safely back home.
