Dogs eating toadstools is a serious concern worldwide, with cases reported in many countries, including the United States, the United Kingdom, and Australia.
In the US, for example, there have been documented cases of dogs eating toadstools in national parks, such as Yellowstone and Yosemite.
Toadstools can be found in many environments, including backyards, parks, and even on hiking trails.
Some common toadstool species that are toxic to dogs include the Destroying Angel and the False Morel.
Dangers of Dogs Eating Toadstools
The Amanita family of mushrooms, such as the Death Cap, are highly toxic to dogs and can cause severe illness or death even with small amounts.
Some mushrooms, like Amanita Muscaria, have a "fishy" odor and taste that can attract dogs, making them a potential threat.
If your dog eats a mushroom, go to a vet immediately to have it removed, and do not wait until signs of illness appear.
Wild mushrooms eaten by people are not necessarily safe in dogs, especially if uncooked.

Dogs with gastrointestinal symptoms require hospital support via intravenous fluids and anti-nausea drugs until symptoms subside.
Dogs with neurological signs may need interventions ranging from diazepam (Valium) to general anaesthesia.
It's difficult to identify which mushrooms are safe and which aren't, so it's best to treat wild mushroom ingestion as poisoning and contact your vet immediately.
If you suspect your dog has eaten a mushroom, it's crucial to act quickly to ensure treatment starts as soon as possible.

Identifying and Preventing Poisoning
Some mushrooms have unpleasant, harsh, or caustic smells, while others have 'scales' and/or raised lumps, white gills, red coloration, or rings around the stem. If you notice any of these characteristics, assume the mushroom is toxic.
A mushroom identifier app can be a helpful tool to identify mushrooms in your area. There are several apps available that can help you identify mushrooms based on their characteristics.
To prevent dogs from eating mushrooms, avoid taking them to damp, warm, wooded areas. If you do need to take your dog to a high-risk area, keep them on a lead and consider using a basket muzzle if they tend to scavenge.
Here are some common signs of mushroom toxicity in dogs:
- Weakness
- Wobbling or loss of balance
- Vomiting
- Salivating
- Dehydration
- Yellowing of skin and whites of eyes
- Sleep-like coma
- Tremors
- Vocalization
- Agitation
- Seizures
If you suspect your dog has eaten a toxic mushroom, contact your veterinarian, animal poison control, or an Animal ER immediately. Delaying treatment can result in more extensive organ damage.
You can also mark "no go zones" where toxic mushrooms have been spotted, using a device like Tractive. This will send you an instant alert if your dog steps out of a safe zone and into a no-go zone.
It's essential to be mindful of mushrooms in your yard, parks, or anywhere your dog plays. Some mushrooms can be deadly to dogs, and what looks innocent can be toxic.
Symptoms and Treatment
Dogs eating toadstools can be a serious issue, and it's essential to know the symptoms and treatment options. The symptoms of mushroom toxicity in dogs can vary depending on the type of mushroom, the amount consumed, and the length of time since ingestion.
If your dog has eaten a mushroom, look out for signs like weakness, wobbling, vomiting, salivating, dehydration, yellowing of skin and whites of eyes, sleep-like coma, tremors, vocalization, agitation, and seizures.
The sooner you bring your dog in for treatment, the better. Delaying treatment can result in more extensive organ damage, which can be costly and may not be enough to save your dog's life.
Treatment for mushroom poisoning typically involves rapid decontamination, which may include inducing vomiting or using activated charcoal. Your vet may also give your dog multiple doses of activated charcoal, especially if they suspect liver or kidney damage.
Some dogs may require close monitoring, especially if they've ingested a mushroom like A. phalloides, which is toxic to the liver or kidneys. In these cases, your vet may administer silibinin, an intravenous treatment that's been shown to be effective.
Here are some common symptoms of mushroom poisoning, grouped by type of toxin:
- Liver damage: No apparent effect for 6-24 hours, followed by gastrointestinal signs, low blood glucose, and liver or kidney failure.
- Nervous signs: Dysphoria, constricted pupils, sedation, trouble walking, seizures, and tremors.
- Gastrointestinal upsets: Vomiting, diarrhoea, dehydration, and lethargy.
- Kidney damage: Rare, but can cause a long delay between eating the mushroom and the onset of signs.
If you suspect your dog has eaten a mushroom, don't wait until symptoms appear - go to a vet immediately to have it removed.
What to Do in Case of Poisoning
If you suspect your dog has eaten a mushroom, act fast and get them to the vet right away. Left untreated, mushroom poisoning in dogs can be deadly.
The treatment your vet will provide depends on the type of poison involved and your dog's symptoms. In some cases, they may induce vomiting using salt water, diluted hydrogen peroxide, or Ipecac.
If your dog has eaten a wild mushroom, travel to a vet straight away for treatment. Emergency after hours vets are listed here. If the vet considers it safe to do so, they will immediately induce vomiting.
If there is any suspicion of mushroom toxin remaining, multiple doses of activated charcoal are often used. A typical recipe is 1 g per 5 ml water given at a dose of 2 to 5 ml per kg bodyweight orally every 2 to 6 hours for 2 to 3 days.
Here are the common symptoms of mushroom poisoning in dogs to watch out for:
- Vomiting
- Diarrhea
- Fever
- Lethargy (weakness and/or inactivity)
- Bleeding
- Yellowing of the skin
- Uncoordinated movements
- Excessive drooling
- Seizures
Even if your dog doesn't seem to have any of these symptoms, but ate mushrooms, it's a good idea to visit your vet. Their symptoms might not turn up until much later – by when your dog's health might have worsened.
Precautions and Safety Measures
Mushrooms can grow quickly and be hard to completely remove from your yard, making it a recipe for disaster if your dog eats one.
If you see mushrooms in your yard, carefully remove one or two and bring them for identification to a local garden store or a local mushroom expert.
To protect your dog from toxic mushrooms on walks and hikes, keep them on a leash and check the areas they're wanting to sniff and explore.
Here are some tips to help prevent ingestion of mushrooms:
- Encourage lots of check-ins using their name recognition cue to stay connected and aware while on your adventure.
- Teaching your dog to "drop it" is especially helpful if you see them munching on something, along with a solid "leave it" cue to prevent them from grabbing something off the ground.
- Carry a mushroom identification book or download a smartphone app.
- Consider teaching your dog to wear a basket muzzle or an OutFox Field Guard if they have a habit of eating things off the ground.
Are Garden Grows Dangerous?
Mushrooms growing in your garden are still considered wild mushrooms and can be a hazard to your dog's health.
It's essential to remove these quickly so your dog isn't tempted to eat them. This is because mushrooms can grow very quickly, and they can be hard to completely remove from your yard.
Some mushrooms can be deadly to dogs, with the death cap (Amanita phalloides) being responsible for the majority of mushroom poisonings globally.
Be mindful of mushrooms in your yard, parks, or anywhere outside your dogs play. What looks innocent can be deadly to your furry family members.
If you suspect your dog has eaten a mushroom, take them to the vet immediately. While only a few types of mushrooms are toxic to dogs, it can be difficult to identify exactly what kind of mushroom they've consumed.
Here are some poisonous mushrooms to watch out for:
- Death cap (Amanita phalloides)
- Deadly webcap (Cortinarius rubellus)
- Destroying angel (Amanita virosa)
- Funeral bell (Galerina marginata)
- Fool’s funnel (Clitocybe rivulosa)
- Panther cap (Amanita pantherina)
- Angel’s wings (Pleurocybella porrigens)
Mark out "no go zones" where you've spotted toxic mushrooms to keep your dog safe. This can be done using a device like Tractive, which allows you to set up instant escape alerts on your phone.
Protecting Yourself on Walks and Hikes
It's essential to be mindful of your surroundings while walking or hiking with your dog. Keep your dog on a leash and carefully check the areas they want to explore to avoid accidental ingestion of mushrooms.
Carrying a mushroom identification book or downloading a smartphone app can be a lifesaver. This way, you can quickly identify potential toxic species and take necessary precautions.
If you're prone to getting lost or separated from your dog, make sure to carry a means of communication, such as a phone or a two-way radio. This will help you stay connected and find your way back to your dog if needed.
If you're hiking with your dog, consider using a long leash to give them more freedom to roam while still keeping them under control.
Here are some essential items to include in your pet first-aid kit:
- pet-safe hydrogen peroxide
If you suspect your dog has eaten a toxic mushroom, don't hesitate to contact a pet poison hotline or a veterinarian for advice on next steps. Time is of the essence in getting your dog evaluated and treated.

- Another reminder we have to live and love as greatly as we can today, because tomorrow is never guaranteed. At approximately 11:15pm last night myself and @laurenhashianofficial had to make the painful decision to end Brutus' suffering by taking him off of life support and sending his soul to pup heaven. I held his lil' paw as he was finally at peace. As all puppies and dogs do, he ate a mushroom while playing outside with his brother Hobbs. This mushroom happened to have a lethal toxicity and within hours it was rapidly destroying his liver and immune system to the point of no return. I encourage all of you out there to be mindful of mushrooms in your yards, parks or anywhere outside your dogs play. What looks innocent, can be deadly to your lil' family members. Thank you Dr. Deckelbaum and Dr. West and the incredibly caring nurses and staff at The Animal Medical Center At Cooper City. We'll always love you Brutus.. and you'll always be my lil' main man and rough housing Brute. #RIPBrutus #WishICouldHaveSavedYouOneMoreTime #TheresPickUpTrucksInHeavenYouCanPeeIn (instagram.com)
