Can Dogs Eat Mushrooms On Pizza?

Typically, your dog can eat mushrooms found in pizza, but you still need to be cautious about their variety, quality, and other potentially toxic ingredients present in the pizza.

If so, can you give dogs mushrooms? It depends on various factors, such as the type, quantity, and frequency that the owner feeds the dog mushrooms.

While some mushrooms are safe for canines, many are toxic and can cause severe or fatal reactions.

Generally, if your pet consumes a few mushroom pieces once you cooked them, it will not be harmful.

However, the situation becomes more dangerous if you discover your dog digging and consuming unknown mushrooms in the yard.

Therefore, you must familiarize yourself with the fundamental kinds of mushrooms and their effects on your dog by reading the sections below.

Mushroom Types And Their Impact On Canine Health

Safe Mushrooms And The Benefit

White button mushrooms and cremini mushrooms are two of the most well-known varieties of mushrooms considered safe for canines.

They are members of the same species (Agaricus bisporus) but at distinct stages of development.

Cremini mushrooms are larger and more mature than white button mushrooms, which are tiny and immature.

They both have strong and appealing flavors, making them good options for pizza and other foods.

These mushrooms are abundant in beneficial nutrients and low in calories. They are rich in fiber, protein, and minerals that are essential for dogs’ health.

In addition, they contain vitamins B and D, which contribute to a balanced diet for canines.

Besides that, your dog can also consume other types of mushrooms. The Portobello mushroom is a larger and more mature variant of the white button mushroom.

They are the popular ingredients in various dishes, including grilling, due to their flavorful and tender texture.

Similarly, Porcini Mushrooms, or Piglet Mushrooms, have a delectable aroma and are widely used in cooking.

Another common edible mushroom is Enoki, which has long, slender stems and can easily be found in stir-fries and hotpots.

Toxic Mushrooms And The Risk

On the flip side, several kinds of mushrooms are toxic to puppies and pose significant risks to their health.

The Amanita genus, which includes Death Cap and Fly Agaric, is one of the most hazardous types.

Death Cap

Death Cap is native to Europe but has spread to other regions worldwide, including North America. It is commonly found near oak, chestnut, and beech trees.

Death Cap has a smooth, olive-green to yellowish cap, often with white patches or spots.

The gills are white, and the stem is white with a cup-like structure at the base, known as the volva.

This lethal mushroom contains amatoxins, a class of extremely poisonous compounds.

Even modest amounts of Death Cap can bring about irreversible liver and kidney damage if consumed. It causes the preponderance of mushroom-related deaths worldwide.

Fly Agaric

Fly Agaric is widespread in temperate regions of Europe, Asia, and North America. It is often found in association with certain tree species, like birch and pine.

Fly Agaric is recognizable by its vibrant red cap with white patches or spots. It has white gills and a distinct, bulbous stem covered in white or yellowish warts.

Fly Agaric contains psychoactive compounds, such as muscimol and ibotenic acid. While not usually deadly, consuming this mushroom can cause significant discomfort and illness.

False Morels

False Morels, members of the genus Gyromitra, are found in various regions around the world, predominantly in North America and Europe.

They often grow in forested areas, especially near coniferous trees.

False Morels have a distinctive wrinkled, lobed, or brain-like appearance. Unlike true morels, they have a cap that is attached to the stem.

False Morels contain hydrazine toxins, which are highly poisonous and can cause severe gastrointestinal issues.

Common Types Of Mushrooms On Pizza

Currently, the mushroom varieties commonly used on pizza are harmless for dogs.

All three members of the family Agaricus bisporus have a robust flavor and a dense, fleshy texture, making them a flavorful ingredient to pizza.

In addition, Shiitake Mushroom, a variety of mushrooms native to Japan, is used as a common pizza topping in Asia.

Likewise, Oyster Mushroom is frequently included in vegetarian pizzas due to its sweet and mellow flavor, providing consumers with a comforting experience.

Symptoms And Effects Of Mushroom Toxicity On Dogs

Immediate Symptoms Of Mushroom Toxicity

Shortly after ingesting mushrooms, a dog may experience various acute symptoms. They may vary depending on the type and quantity of mushrooms consumed.

Vomiting, diarrhea, excessive drooling, abdominal pain, and restlessness are prevalent instant symptoms.

Indicators of neurological distress in dogs may also involve indications of weakness, tremors, or seizures.

In some cases of mushroom toxicity, puppies may exhibit a rapid heart rate, trouble breathing, or collapse.

Potential Long-Term Health Effects

The long-term effects of mushroom toxicity on a dog’s health can be severe and even fatal. The liver and kidneys are especially susceptible to injury from toxic mushrooms such as Death Cap.

These mushrooms consist of poisonous compounds that can cause irreversible organ damage and failure over time.

Sometimes, canines may recover from immediate symptoms, but complications may develop days or weeks later.

Delayed liver and kidney failure can be mortal and requires prompt veterinary intervention.

Certain mushrooms also contain toxins that impact the central nervous system and lead to lasting neurological issues.

These side effects may include recurrent seizures, tremors, and behavioral or coordination changes.

Safe Alternatives And Precautions For Feeding Mushrooms To Dogs

Consulting With Your Veterinarian

Before introducing any new substance to your dog’s diet, it is vital to consult with a veterinarian. Each dog has unique dietary requirements and potential sensitivities.

Your vet can provide individualized guidance regarding whether mushrooms are edible for your canine and in what quantity.

Some commercially available types of dog foods may contain mushrooms.

When purchasing them, you should thoroughly examine the label for the presence of mushrooms.

Use only trustworthy brands and products with transparent ingredient listings. If you have questions about an ingredient, conduct further research or consult your veterinarian.

Homemade Pizza For Dogs

If you enjoy sharing pizza time with your puppies, consider making a homemade version for them.

You can control the ingredients and feel comfortable when your dog eats mushroom pizza.

Choose safe garnishes such as cooked white button mushrooms, plain chicken, or vegetables like carrots and green beans.
