The question of whether dogs can get high off mushrooms is a concerning and increasingly relevant topic, as accidental ingestion of wild mushrooms by pets is not uncommon. While some mushrooms are harmless, others contain psychoactive compounds like psilocybin, which can cause significant health risks to dogs, including severe gastrointestinal distress, neurological symptoms, and even potential toxicity. Unlike humans, dogs metabolize substances differently, making them more susceptible to adverse reactions, and there is no evidence to suggest that dogs experience a high in the same way humans might. Instead, ingestion of psychoactive mushrooms can lead to dangerous and distressing symptoms, emphasizing the importance of pet owners being vigilant about their surroundings and seeking immediate veterinary care if they suspect their dog has consumed mushrooms.

Types of Mushrooms Affecting Dogs
Dogs, like humans, can encounter a variety of mushrooms in their environment, but not all mushrooms affect them in the same way. While some are harmless, others can cause severe toxicity or even induce psychoactive effects. Understanding the types of mushrooms that can affect dogs is crucial for pet owners to prevent accidental ingestion and ensure their pet’s safety.
Amanita Mushrooms: The Psychoactive Threat
Among the most notorious mushrooms affecting dogs are species from the *Amanita* genus, particularly the Amanita muscaria (fly agaric) and Amanita pantherina. These mushrooms contain psychoactive compounds like muscimol and ibotenic acid, which can cause hallucinations, disorientation, and lethargy in dogs. Even small amounts, such as 10–20 grams for a medium-sized dog, can lead to symptoms within 30 minutes to 2 hours. If ingested, immediate veterinary attention is essential, as severe cases can result in seizures or coma.
Psilocybin Mushrooms: A Milder but Risky High
Psilocybin mushrooms, often referred to as "magic mushrooms," contain psilocybin and psilocin, compounds that can cause euphoria, restlessness, and disorientation in dogs. While the effects are generally milder than those of Amanita mushrooms, they can still be distressing for the animal. A dose of 0.1–0.5 grams per kilogram of body weight can lead to symptoms like drooling, vomiting, and uncoordinated movement. Pet owners should avoid areas where these mushrooms grow, especially during wet seasons when they thrive.
Non-Psychoactive but Toxic Varieties: A Hidden Danger
Not all mushrooms that harm dogs are psychoactive. Species like the Amanita phalloides (death cap) and Galerina marginata contain toxins like amatoxins, which can cause severe liver and kidney damage. These mushrooms do not induce a "high" but are far more dangerous, often leading to fatal outcomes if untreated. Even a single bite can be lethal, particularly in smaller breeds or puppies. Symptoms, such as vomiting, diarrhea, and lethargy, may appear 6–24 hours after ingestion, making early detection critical.
Prevention and Practical Tips for Pet Owners
To protect dogs from mushroom toxicity, owners should regularly inspect their yards and walking routes, especially after rain. Keep dogs on a leash in wooded or grassy areas where mushrooms are likely to grow. If ingestion is suspected, collect a sample of the mushroom (if safe) and contact a veterinarian immediately. The ASPCA Animal Poison Control Center (APCC) can also provide guidance. Prompt action can mean the difference between a full recovery and a tragic outcome.
In summary, while dogs can indeed be affected by mushrooms, the type of mushroom determines whether the effect is psychoactive, toxic, or both. Awareness and vigilance are key to safeguarding pets from these hidden dangers.

Symptoms of Mushroom Intoxication
Dogs, like humans, can experience mushroom intoxication, but the symptoms and severity depend largely on the type of mushroom ingested. Not all mushrooms are psychoactive or toxic, yet those that are can lead to a range of alarming reactions. For instance, Amanita species, commonly known as death cap or destroying angel mushrooms, contain toxins that can cause severe liver and kidney damage within 6 to 24 hours. In contrast, psilocybin mushrooms, which contain hallucinogenic compounds, may produce behavioral changes such as restlessness, agitation, or apparent hallucinations in dogs, though these cases are less common and often milder than in humans.
Recognizing the symptoms of mushroom intoxication is critical for prompt intervention. Early signs often include gastrointestinal distress, such as vomiting, diarrhea, and abdominal pain, which can appear within 30 minutes to 2 hours of ingestion. These symptoms may be accompanied by excessive drooling, a clear sign of oral irritation or nausea. As the toxins progress through the dog’s system, more severe symptoms like seizures, tremors, or uncoordinated movements may develop, particularly with neurotoxic mushrooms. In cases of Amanita poisoning, a deceptive "quiet phase" may occur 24 hours after initial symptoms, followed by acute liver failure, jaundice, and potentially coma or death if untreated.
Dosage plays a significant role in the severity of symptoms, but determining the exact amount ingested is rarely possible. A small dog may exhibit severe symptoms from a single toxic mushroom, while a larger breed might tolerate a slightly higher dose. Age and overall health also influence susceptibility; puppies and elderly dogs with compromised immune systems are at higher risk. Pet owners should never attempt to induce vomiting without veterinary guidance, as some toxins can cause further damage when regurgitated. Instead, immediate contact with a veterinarian or animal poison control is essential.
Practical tips for prevention include keeping dogs on a leash during walks in wooded or grassy areas and thoroughly inspecting yards for mushrooms, especially after rain. If ingestion is suspected, collect a sample of the mushroom (if safe) for identification by a professional. Time is of the essence, as early treatment—such as activated charcoal to bind toxins or supportive care for organ failure—can significantly improve outcomes. While not all mushroom exposures are life-threatening, the potential for severe toxicity underscores the importance of vigilance and swift action.

Toxicity Levels in Dogs
Dogs can ingest mushrooms, but not all mushrooms affect them the same way. The toxicity level depends on the mushroom species, with some causing mild gastrointestinal upset and others leading to severe, life-threatening symptoms. For instance, Amanita species contain toxins like amatoxins, which can cause liver failure within 24–48 hours of ingestion. Even a small amount—as little as 0.1 mg/kg of body weight—can be fatal. In contrast, Psilocybe mushrooms, known for their psychoactive properties in humans, may cause disorientation or agitation in dogs but are less likely to be lethal unless consumed in extremely large quantities.
Identifying the mushroom type is critical for assessing toxicity levels. If ingestion is suspected, immediate veterinary consultation is essential. Symptoms of mushroom poisoning vary widely: mild cases may present as vomiting or diarrhea, while severe cases can include seizures, jaundice, or coma. Age and size play a role in a dog’s reaction; puppies and small breeds are more susceptible due to their lower body weight, meaning even trace amounts can be dangerous. Always keep detailed records of symptoms and, if possible, bring a sample of the mushroom to the vet for identification.
Prevention is the best approach to managing mushroom toxicity. Avoid walking dogs in areas where mushrooms grow, especially after rain, as this is when they proliferate. Teach dogs the "leave it" command to prevent accidental ingestion. If mushrooms appear in your yard, remove them promptly and monitor the area regularly. For households with curious or foraging dogs, consider fencing off wooded sections or using pet-safe repellents to deter mushroom growth.
Treatment for mushroom toxicity depends on the severity and type of exposure. In mild cases, vets may induce vomiting or administer activated charcoal to prevent toxin absorption. Severe cases often require hospitalization, intravenous fluids, and medications to protect the liver or manage symptoms. In extreme situations, such as amatoxin poisoning, dogs may need a liver transplant or plasma transfusions. Early intervention significantly improves outcomes, so never delay seeking veterinary care if mushroom ingestion is suspected.
Understanding toxicity levels in dogs highlights the importance of vigilance and education. While not all mushrooms are deadly, the risk is too great to ignore. Familiarize yourself with common toxic species in your region, and stay alert during outdoor activities. Quick action, combined with preventive measures, can save a dog’s life and spare them unnecessary suffering. Always prioritize caution—when in doubt, consult a professional.

Immediate Treatment Steps
Dogs can ingest mushrooms, both wild and cultivated, and some species contain toxins or psychoactive compounds that may affect them differently than humans. If you suspect your dog has consumed mushrooms, immediate action is crucial to prevent potential harm. The first step is to remain calm but act swiftly. Contact your veterinarian or an emergency pet poison hotline immediately, providing details about the type of mushroom (if known), the amount ingested, and your dog’s size, age, and current symptoms. Time is critical, as some toxins can cause severe symptoms within hours.
While waiting for professional guidance, observe your dog closely for signs of distress, such as vomiting, diarrhea, drooling, lethargy, or seizures. Do not induce vomiting unless instructed by a veterinarian, as some mushroom toxins can cause further damage if regurgitated. If possible, collect a sample of the mushroom or take a clear photo to aid in identification. This information can help the vet determine the appropriate treatment plan, which may include gastric decontamination, activated charcoal administration, or supportive care.
In cases of psychoactive mushrooms, dogs may exhibit behavioral changes like disorientation, agitation, or hallucinations. While these symptoms may seem less urgent than physical toxicity, they can still lead to dangerous situations, such as accidental injury or escape. Keep your dog in a safe, quiet space to minimize stress and prevent harm. Avoid giving any food, water, or home remedies without veterinary approval, as these could interfere with treatment.
For puppies, seniors, or dogs with pre-existing health conditions, the risks of mushroom ingestion are heightened. These dogs may require more aggressive monitoring and treatment due to their vulnerable immune systems or reduced organ function. If your dog falls into one of these categories, emphasize this to the veterinarian, as it may influence their recommendations. Remember, early intervention is key to a positive outcome, so trust professional advice over online speculation or home remedies.
Finally, prevention is the best treatment. Educate yourself about common toxic mushrooms in your area and keep your dog on a leash during walks to avoid accidental ingestion. Regularly inspect your yard for fungi growth, especially after rainy periods. By staying proactive, you can reduce the risk of mushroom-related incidents and ensure your dog’s safety in the long term.

Preventing Mushroom Exposure
Dogs, with their curious nature and indiscriminate eating habits, are at risk of ingesting wild mushrooms, some of which can cause severe toxicity or hallucinogenic effects. Preventing mushroom exposure begins with understanding your environment. Mushrooms thrive in damp, shaded areas, such as wooded trails, lawns, and gardens, especially after rain. Regularly inspect these zones and remove any fungi before your dog has a chance to investigate. For urban dwellers, be vigilant during walks in parks or along tree-lined streets, where mushrooms can sprout unexpectedly.
A proactive approach involves training your dog to avoid mushrooms altogether. Start by teaching the "leave it" command, reinforcing it with treats and praise. Use visual aids, like pictures of mushrooms, to help your dog associate the command with the object. For puppies and younger dogs, whose curiosity peaks between 3 and 12 months, consistent training is crucial. Older dogs, while potentially less exploratory, can still benefit from refresher sessions, especially in new environments.
Physical barriers are another effective strategy. Fencing off garden areas or using pet-safe repellents can deter dogs from accessing mushroom-prone spots. During walks, keep your dog on a short leash in high-risk areas, and avoid letting them sniff or forage freely. For particularly determined dogs, consider a basket muzzle, which allows breathing and panting while preventing ingestion of harmful substances.
Finally, stay informed about local mushroom species and their potential risks. Apps like iNaturalist or consultations with mycologists can help identify dangerous varieties in your area. If you suspect your dog has ingested mushrooms, note symptoms like vomiting, diarrhea, lethargy, or unusual behavior, and contact a veterinarian immediately. Time is critical, as some toxins can cause irreversible damage within hours. Prevention, paired with knowledge, is your best defense against mushroom-related incidents.
