Puffball mushrooms are not inherently poisonous to dogs, but consuming mature puffballs can be toxic and cause lung inflammation or liver toxicity. Additionally, the spores of certain puffball mushrooms can cause inhalation pneumonitis in dogs, leading to symptoms such as fever, dyspnea, and lethargy. Therefore, it is crucial to identify the specific type of puffball mushroom and its stage of maturity before determining its safety for dogs. Incorrect identification of mushrooms can lead to potential health risks, so caution is advised.

Puffball mushroom look-alikes can be poisonous
Puffball mushrooms are generally edible and offer health benefits to both humans and dogs when consumed in small amounts. However, it is important to exercise caution as there are poisonous look-alikes that can be dangerous.
One way to identify a puffball mushroom is to cut it in half and examine the inside. If it is pure white, like a marshmallow, then it is likely a puffball mushroom. However, if there are any gills, it is not a puffball. The absence of gills is a critical distinguishing factor as some poisonous mushrooms, such as the destroying angel and death cap, may resemble puffballs in their egg stage but have a stout stem encased in a sac-like volva.
Additionally, the stage of maturity matters. Young puffballs are typically edible, while mature puffballs can turn yellow, brown, or grey and become toxic to dogs. The warted puffball mushroom (Lycoperdon pyriforme) is an example of a puffball that is edible when young but can become toxic as it matures.
It is also important to be aware of potential allergic reactions and the risk of lung inflammation from inhaling spores, as reported in a case of a golden retriever that developed pneumonitis after playing in a bed of puffball mushrooms.
Finally, some puffball mushrooms may have look-alikes that are toxic. For example, the Giant Western Puffball may resemble other species of Cortinarius (Webcaps) that are toxic. Therefore, it is crucial to accurately identify mushrooms before consumption and seek expert knowledge if unsure.

Dogs can eat small amounts of puffball mushrooms
Dogs can eat some puffball mushrooms, but only in small amounts. True puffball mushrooms are edible when they are young and have pure white spongy flesh on the inside. Common puffballs (Lycoperdon perlatum), Giant puffballs (Calvatia gigantea), Purple-spored puffballs (Calvatia cyathiformis), and Grey puffballs (Bovista plumbea) are all edible when young. When the mushrooms are young, the flesh is white and firm, but as they mature, the flesh turns yellow, brown, or grey, and becomes unsafe to eat.
To identify whether a puffball mushroom is safe to eat, cut it in half. If the inside is white and spongy, it is likely safe to feed to your dog in small amounts. If the inside is anything other than white, it is best not to feed it to your dog. It is also important to ensure that the mushroom does not have gills, as this is a sign of a poisonous puffball look-alike.
While some puffball mushrooms are edible, it is important to exercise caution as there are several puffball look-alikes that are poisonous. The Earthball mushroom (Scleroderma citrinum), for example, is brown or reddish-brown with small scales on the surface, while the Destroying Angel (Amanita bisporigera) has a white spherical body with gills on the inside. In addition, the spores of puffball mushrooms can cause lung inflammation in dogs, so it is important to ensure that the mushroom is not filled with spores.
If your dog consumes a poisonous mushroom, it may experience gastrointestinal upset, including vomiting and diarrhea. In some cases, mushroom poisoning can lead to liver toxicity and lung inflammation. If you suspect your dog has eaten a poisonous mushroom, it is important to seek veterinary advice promptly.

Mature puffball mushrooms are toxic to dogs
While puffball mushrooms are edible when young, they become toxic to dogs as they mature. Young puffball mushrooms are characterised by pure white, firm, spongy flesh on the inside. As they mature, the flesh turns yellow, brown, or grey, and becomes softer. At this stage, they are no longer safe for consumption and can be harmful to dogs.
Mature puffball mushrooms can cause sickness in dogs, and their spores can lead to lung inflammation or pneumonitis, a type of inhalation pneumonitis. The spores can cause fever, dyspnea, moist rales, and abnormal mucous membranes. Treatment with antibiotics and corticosteroids can help improve the dog's condition.
It is important to properly identify puffball mushrooms before feeding them to dogs, as there are poisonous look-alikes. True puffball mushrooms are spherical or upside-down pear-shaped, and they do not have gills. If a puffball mushroom is cut open and it is not entirely white and spongy on the inside, it is best to avoid feeding it to dogs.
Additionally, when preparing puffball mushrooms for dogs, it is recommended to lightly cook them by boiling, steaming, or grilling. The outer layer should be peeled, and the mushroom should be cut into bite-sized pieces. If there is any uncertainty about the safety of a puffball mushroom, it is best to avoid feeding it to dogs.

Puffball mushroom spores can cause lung inflammation in dogs
Puffball mushrooms, or Lycoperdon pyriforme, are widely distributed and common in North America and Europe. They are edible when young and fruit from early September to late fall. However, as puffball mushrooms mature, their flesh turns yellow, brown, or gray, and they become toxic. While some sources claim that dogs can eat puffballs without harm, others caution against it, as mature puffballs can make dogs sick.
The treatment for pneumonitis caused by puffball mushroom spores typically involves the use of antibiotics and corticosteroids. In the case of the golden retriever, treatment with amoxicillin and meloxicam was initiated, and the dog's health improved rapidly. However, it is important to note that corticosteroid treatment may not be suitable for all dogs, as there are concerns about its use in cases of fungal spore inhalation. Therefore, a careful diagnosis and tailored treatment plan are crucial for managing pneumonitis in dogs exposed to puffball mushroom spores.
To prevent dogs from inhaling puffball mushroom spores, it is important to avoid areas where these mushrooms are present in large quantities. Additionally, if you suspect your dog has come into contact with puffball mushrooms, it is advisable to seek veterinary advice and have your dog's vitals monitored to ensure their health and well-being.
Overall, while puffball mushrooms may not always be harmful to dogs when ingested in small amounts, the spores they release can pose a significant risk of lung inflammation. As such, it is crucial for dog owners to be vigilant about their dogs' exposure to these mushrooms and to seek prompt veterinary care if any concerning symptoms arise.

How to identify a puffball mushroom
While foraging for puffball mushrooms, it is important to be able to identify them, especially since there are a few toxic look-alikes. Here are some ways to identify a puffball mushroom:
Shape and Texture
Puffball mushrooms are usually round or spherical. In some cases, they may have a stem-like base or be pear-shaped. They are fleshy and soft, with a thick outer surface that is never hard. They are also solid and lack gills.
Size
Puffballs can range in size from a couple of centimetres to a meter. If your mushroom is the size of a soccer ball, it is likely an edible giant puffball.
Colour
When identifying a puffball mushroom, colour is an important factor. Edible puffballs are pure white inside, while toxic puffballs will be any other colour, such as black, yellow, green, or brown.
Spore Mass
Edible puffballs tend to have a powdery spore mass once the mushroom is mature. However, puffballs are no longer edible once they form a spore mass.
Habitat
Puffballs can be found in a variety of habitats, including trails, roadsides, pastures, forests, deserts, and mountains. They grow directly from the ground or from woody debris.
Smell
Common puffballs may smell like gas when cut open.
It is important to note that while puffballs are generally easy to identify, there are toxic look-alikes, so it is always best to err on the side of caution when foraging.
