Accidental drug poisoning in dogs is more common than many pet owners realize. Dogs are naturally curious animals, exploring the world through sniffs and licks. Unfortunately, this curiosity can lead them to ingest harmful substances, like illegal or recreational drugs. It often occurs when a dog sniffs out or consumes dropped substances, unattended bags, edible cannabis products, or other drug-containing items, whether at home, at a party, on a walk, or even at the dog park.

As a pet owner, knowing the signs of drug toxicity in dogs and when to seek emergency veterinary care are potentially life-saving skills. Even a small amount of certain drugs can cause serious poisoning, seizures, breathing problems, or other life-threatening complications in pets. In this blog, you'll learn how to:

• recognize the warning signs of drug toxicity in dogs

• understand the risks associated with different substances

• Know when it’s time to bring your pup to your nearest VEG ER for Pets for emergency care.

Signs your dog may have ingested drugs

While discovering your dog has ingested a drug can be alarming, responding quickly and seeking appropriate emergency veterinary care can vastly improve the outcome for your pet. The symptoms of drug ingestion in dogs will vary by substance but may include:

• Agitation or hyperactivity

• Tremors or seizures

• Excessive drooling

• Vomiting

• Disorientation or unusual behavior

• Rapid or slow heart rate

• Difficulty walking or standing

• Collapse or loss of consciousness

If you suspect your dog has ingested a drug through its nose or mouth, even if you're unsure of what was consumed, you should always treat it as an emergency. Bring your pet to VEG for a thorough evaluation with our team of knowledgeable emergency vets.

Cocaine ingestion in dogs

Cocaine (also known as coke or crack) is an extremely potent stimulant, and even small amounts can be toxic to dogs, leading to dangerous changes in heart rate, body temperature, blood pressure, and brain activity.

Symptoms of cocaine toxicity in dogs

• Extreme restlessness

• Hyperactivity

• Elevated heart rate

• High body temperature

• Tremors

• Seizures

• Collapse

If your dog has ingested cocaine, don’t wait for symptoms to appear or improve—seek emergency veterinary care at VEG immediately. If possible, bring any remaining packaging or information about the substance.

If your dog has ingested a drug, don’t wait for symptoms to appear—seek emergency care at VEG immediately.

Signs of hallucinogen toxicity in dogs

Hallucinogenic drugs, including psilocybin (“shrooms” or “magic mushrooms”), LSD, MDMA (ecstasy), and other recreational drugs, alter perception, mood, thoughts, and sensory experiences. In dogs, exposure to these substances disrupts normal brain and nervous-system function, which can be life-threatening. Your curious dog may find these substances at home, during gatherings, or while exploring outdoor areas.

They may also ingest unidentified powders, capsules, or tablets that have been dropped or left within reach. Because many recreational drugs look similar and may contain multiple ingredients, it is often impossible to know exactly what a dog has consumed without testing.

If your dog has consumed hallucinogenic drugs, they may exhibit the following symptoms:

• Disorientation

• Vocalizing or unusual behavior

• Dilated pupils

• Agitation

• Loss of coordination

• Tremors or seizures

• Changes in heart rate and body temperature

The effects of hallucinogens on dogs can be unpredictable, and symptoms may worsen rapidly. Bring your dog to VEG for emergency care right away if your dog has ingested a hallucinogenic drug like psilocybin, LSD, or MDMA, or if you suspect they may have ingested any of these substances.

Methamphetamine toxicity in dogs

Methamphetamine is a potent stimulant that can have devastating effects on a dog's nervous and cardiovascular systems. Even a small amount may trigger severe, rapidly progressing symptoms that require immediate medical attention. Because the drug overstimulates the body, it can lead to dangerous increases in heart rate, blood pressure, and body temperature, placing dogs at risk for life-threatening complications.

Symptoms of methamphetamine ingestion in dogs

• Intense hyperactivity

• Panting

• Elevated body temperature

• Rapid heart rate

• High blood pressure

• Tremors

• Seizures

• Collapse

If your dog ingests methamphetamines, do not attempt home treatment. Instead, bring them to your nearest VEG for immediate evaluation by an emergency veterinarian.

Ingestion of marijuana and THC edibles in dogs

Marijuana exposure in dogs is becoming increasingly common, especially as cannabis products become more widely available in homes. Dogs process THC differently than humans, and even small amounts may cause noticeable effects for your canine companion. Pets are also more likely to consume concentrated products, such as edibles, which can result in more severe toxicity.

Common symptoms of marijuana and THC ingestion in dogs include:

• Sleepiness or profound lethargy

• Wobbliness

• Dribbling urine

• Dilated pupils

• Vomiting

• Low heart rate

• In severe cases: seizures or coma

While marijuana (also known as weed or pot) itself may not seem as dangerous as some of the other substances mentioned here, edible THC products are more likely to include other additives that are harmful to dogs, like chocolate, xylitol, raisins, or large amounts of fat, creating additional toxic risks for your pup.

Closely supervise pets during parties, and inform guests not to feed pets human foods or substances.

How to keep your dog safe at home and at parties

Accidents are bound to happen with a pup around, but there are some practical things you can do to prevent them from sticking their nose where it doesn’t belong. To keep your pet safe from accidental drug exposure:

• Store all drugs securely out of reach and in pet-safe containers.

• Keep purses, backpacks, and jackets off the floor.

• Never leave drinks or infused foods unattended.

• Clean up after usage and safely dispose of drug waste.

• Closely supervise pets during parties, holidays, and other gatherings.

• Inform guests not to feed pets human foods or substances.

• Be especially vigilant after gatherings when dropped items may remain on the floor.

• Don’t allow pets to consume unknown items outdoors or on walks.

When should you go to an emergency vet?

Pet owners should seek emergency veterinary care whenever they witness or strongly suspect that their dog has ingested a drug or unknown substance. Immediate evaluation is especially important if a dog develops unusual behavior after possible exposure or shows signs of drug poisoning, such as tremors, seizures, collapse, difficulty breathing, or severe lethargy. If the amount or type of substance involved is unknown, it is safest to treat the situation as an emergency.
