Have you ever seen your dog sniffing around in the grass or munching on something they found during a walk, or maybe you're thinking of sharing leftover mushrooms with them? You might be wondering if it's safe for them to eat.
Some mushrooms are harmless, but others can be toxic and cause serious harm to your dog. If your puppy is eating mushrooms outside or you’re thinking of sharing your meal, it’s important to know which mushrooms are safe and which ones to steer clear of. Let’s take a closer look at what’s safe for your pup and what’s not!
Safe Mushrooms for Dogs
While many wild mushrooms are dangerous, certain store-bought mushrooms are perfectly safe for dogs to eat in moderation. These varieties are commonly found in grocery stores and can be a healthy treat when prepared properly:
-
White button mushrooms: These mild-flavored mushrooms are one of the most common types found in grocery stores and are safe for dogs when cooked without any seasoning.
-
Cremini mushrooms: Similar to white button mushrooms but with a slightly richer flavor, cremini mushrooms are also safe for dogs to eat in small amounts.
-
Portobello mushrooms: Larger and meatier than cremini or white button mushrooms, portobellos are high in fiber and low in calories, making them a great option for dogs needing to maintain a healthy weight.
-
Porcini mushrooms: These mushrooms are often used in cooking for their earthy flavor and are safe for dogs in moderation, as long as they’re cooked plainly.
-
Shiitake mushrooms: Known for their unique taste and health benefits, shiitake mushrooms are safe for dogs when served in small portions.
-
Reishi mushrooms: Often used for their medicinal properties, reishi mushrooms are non-toxic to dogs but should be given in small amounts.
-
Maitake mushrooms: Known for their immune-boosting properties, maitake mushrooms are safe for dogs when offered in moderation.
Potential Health Benefits of Safe Mushrooms
Beyond being safe to eat, many mushrooms provide valuable nutritional benefits for your dog. Including these mushrooms can contribute to their overall well-being. Let’s take a closer look at some of the health benefits these mushrooms offer:
-
Nutritional Benefits
Mushrooms like white button, cremini, and portobello are rich in essential minerals like potassium, copper, and phosphorus, which help support healthy bone growth, nerve function, and muscle contraction. They also provide vitamin B that help boost energy levels and metabolism in dogs.
-
Digestive Health
Many mushrooms, such as shiitake and maitake, are high in fiber and contain prebiotics that support gut health. Prebiotics help stimulate the growth of beneficial bacteria in your dog’s digestive system, promoting better digestion and nutrient absorption.
-
Immune System Support
Certain mushrooms, like reishi and shiitake, have powerful antioxidants and compounds that can strengthen your dog’s immune system. These mushrooms help protect the body from oxidative stress and inflammation, supporting overall health and helping to fight off infections.
However, just because some mushrooms are safe and nutritious doesn’t mean all of them are. In fact, many wild mushrooms can be incredibly toxic to dogs.
So, if your dog picks up a mushroom on a walk, or you’re unsure about a mushroom in your backyard, it’s important to know what to avoid which brings us to our next point.
Identifying Poisonous Mushrooms
When it comes to mushrooms, not all are safe for dogs, and the danger of poisoning is real, especially with wild mushrooms. There are several characteristics you can look for that are often found in toxic species.
While it can be tricky to spot the harmful ones, knowing these features can help you avoid dangerous situations:
-
White gills: The underside of a mushroom cap is often white in many toxic species, which can be a clear indicator of potential danger.
-
Bright red coloring: If you spot a mushroom with vibrant red hues on its cap or stem, be cautious. Many poisonous varieties, like Amanitas, are known for their striking red coloring.
-
Ring around the stem: A ring, or annulus, around the stem of the mushroom is another feature that is commonly seen in toxic species. This could be an easy visual cue.
-
Bulbous base: Some mushrooms, particularly those in the Amanita family, have a bulbous base that’s often buried underground, making them easy to miss but potentially deadly if ingested.
If you spot a mushroom with any of these features, it’s crucial to keep your dog away from it and in case of accidental ingestion, contact a vet immediately. Poisonous mushrooms can cause everything from mild gastrointestinal upset to life-threatening organ failure.
Dangerous Mushrooms to Watch Out For
While there are thousands of mushroom species, some are especially harmful to dogs. These toxic mushrooms may look harmless at first glance, but they contain potent toxins that can lead to serious health issues.
Here are a few dangerous ones to look out for:
Mushroom Name |
Appearance |
Toxic Effects |
Death Cap |
White stem, yellow-green cap, white gills |
Liver and kidney damage, organ failure |
Autumn Galerina |
Small, brown, found on decaying wood |
Liver failure, delayed symptoms |
Jeweled Deathcap |

Even experienced mushroom hunters can struggle to differentiate between safe and toxic varieties, so it's always safer to assume that wild mushrooms are harmful.
Symptoms of Mushroom Poisoning in Dogs
If your dog has ingested a poisonous mushroom, it's important to recognize the symptoms as quickly as possible. Mushroom poisoning can have varying effects depending on the type of mushroom and the amount consumed. Some mushrooms may cause mild discomfort, while others can lead to serious health complications. Here’s what to watch for:
-
Common Symptoms: Most dogs will experience basic symptoms like vomiting, diarrhea, and drooling shortly after eating a toxic mushroom. These are often the first signs of distress and should not be ignored.
-
Severe Effects: In more serious cases, symptoms may escalate to weakness, seizures, liver failure, and even coma. These effects can quickly become life-threatening, especially if the poisoning is left untreated.
-
Varied Symptoms: Keep in mind that the symptoms your dog exhibits will depend on the type of mushroom they ate and how much they consumed. Some mushrooms can cause delayed symptoms, while others show immediate effects.
If you suspect your dog has eaten a poisonous mushroom, it's crucial to seek veterinary care right away. Prompt treatment can make a big difference in the outcome, especially for severe cases of mushroom poisoning.
Perfect Snack for your Dog
Mushrooms can be a tasty and nutritious snack for your dog when prepared properly. But to make the treat even more balanced, you can pair them with healthy, pup-friendly snacks. One option to consider is adding a nutritious biscuit, like Shmush Pets' AM and PM biscuits, which are packed with vitamins to support your dog’s health.
Here are a few ways you can combine store bought mushrooms with these healthy snacks:
-
Mushroom and AM Biscuit (Breakfast Snack)
After preparing your dog’s mushrooms (cooked and chopped into bite-sized pieces), crumble a Shmush AM Biscuit on top. These biscuits are packed with special ingredients to support your dog’s energy levels and help them start their day right.
-
Mushroom & PM Biscuit (Bedtime Snack)
Serve a small portion of cooked mushrooms alongside a Shmush PM Biscuit. The PM biscuits are designed to help your dog relax and wind down before bedtime. Pairing them with mushrooms makes a calming snack that can promote a peaceful night’s sleep.
-
Mushroom Broth & Biscuit Dip
For a fun twist, serve mushroom broth (made by cooking mushrooms in water and straining) in a bowl, and let your dog dip their Shmush biscuit into it. This not only makes the snack more engaging, but also adds extra hydration.
Final thoughts
Mushrooms can be a healthy and enjoyable snack for your dog when prepared properly, but they should never replace a balanced diet. They are best served as an occasional treat or snack option rather than a main meal.
A dog’s primary diet should consist of a balanced combination of fats, proteins, and fiber to support their overall health.
Whether you choose Shmush Pets' AM and PM biscuits on their own or pair them with other treats like mushrooms, you're giving your dog a snack that’s delicious and packed with essential vitamins and nutrients to support their overall health and well-being.
The AM biscuits provide energizing ingredients for daytime, while the PM biscuits offer calming ingredients perfect for bedtime. For healthy, vitamin-packed treats for your dog, visit Shmush Pets and explore our products designed to support your beloved pet's health throughout the day.
