37 Fruits, Vegetables & Other Snacks Mastiffs Can (And Can’t) Eat

Have you wondered which human food your Mastiff can or can’t eat?

The truth is, dogs have different metabolic systems than ours. That’s why what’s safe food for us may not be safe for our Mastiff, and vice versa. In other words, you need to know which foods are good (and bad) for your Mastiff if you want to keep her healthy.

Below are the most common 37 fruits, vegetables & other snacks Mastiffs can (and can’t) eat:

List of fruits Mastiffs can or can’t eat

Wondering which fruits your Mastiff can eat or not? Here is a list of some common fruits your Mastiff can or can’t eat:


YES. Mastiffs can eat apples.

Apples are an excellent source of vitamins A and C, as well as fiber for your Mastiff. They’re also low in protein and fat—making them the perfect snack for senior Mastiffs.

However, you should be careful when feeding your Mastiff apples: remove the seeds and core first, as they contain cyanide that can be harmful to your pet. Also avoid processed apples like applesauce and apple pies—they often have added sugar which can cause diarrhea in Mastiffs.


Avocados aren’t safe for Mastiffs to eat.

The avocado fruit, pits, leaves, skin and the actual plant contain persin so these parts are potentially poisonous to your Mastiff. It’s not clear how much of this toxin is in each piece of avocado, but it’s not worth the risk.

Avocado oil is safe in small amounts, but keep it away from your Mastiff! There’s always a chance of overindulgence that can be harmful for your Mastiff.


The answer to the question “Can Mastiffs eat bananas?” is yes!

But before you munch on your Mastiff’s favorite fruit, there are a few things you should know.

While bananas are a low-calorie snack for Mastiffs in moderation and are full of potassium, vitamins, biotin, fiber, and copper—they also contain high sugar content. That means that even though bananas are a great treat for your Mastiff now and then, we should give them as an occasional treat.

Bananas have been shown to help with the digestion of other foods and can help prevent constipation in Mastiffs. They also contain antioxidants that may help prevent cancer in Mastiffs‌.

If you’re thinking about feeding your Mastiff some banana chips or some other kind of processed banana product—think again. Processed bananas can contain added toxic ingredients that aren’t safe for your Mastiff to eat.


It is safe for Mastiffs to eat blackberries.

Blackberries are low in calories and sugar, but high in vitamins, minerals and antioxidants. They can be consumed fresh or frozen, either is fine. However, avoid processed blackberries like blackberry jam, jelly, blackberry-flavored ice cream, as they may contain harmful preservatives.

The recommended serving size is two blackberries per 10 pounds of body weight per day.


Yes, Mastiffs can eat blueberries.

Blueberries are a great food for Mastiffs, as they are high in vitamins and minerals. They also contain antioxidants, which help to fight free radicals in the body. Anyway, Mastiffs have a low tolerance for sugar, so you can feed them in moderation. If your pup weighs 10 pounds, you can feed them 4-5 blueberries per day.

You can give your Mastiff frozen blueberries or fresh ones—either is fine for most pups. You can also give them dried blueberries or mashed up blueberries (just pureeing the berries into a smoothie or soup). You should avoid processed blueberries like those found in muffins, yogurt, pies, pancakes and so on because they may contain harmful food additives.


Yes, a Mastiff can eat cantaloupe!

It’s true that the fruit is low in calories, but it’s also high in other nutrients. It has fiber and moisture, which Mastiffs need to stay hydrated and healthy.

However, it is also high in sugar, so give your Mastiff cantaloupe in moderation. Remove the rinds and seeds before serving; they’re choking hazards for Mastiffs.


It’s a common misconception that Mastiffs can eat cherries. But while the fleshy part around the seed is safe, cherry plants contain cyanide—a substance that destroys cellular oxygen transport in your Mastiff and can cause symptoms like dilated pupils.

If you suspect your Mastiff ate cherries, contact your vet immediately.


Can Mastiffs eat grapes?

The answer is no. Grapes are very toxic to Mastiffs, even in small amounts. Grapes can cause an acute kidney failure called “grape poisoning” in your Mastiff. Symptoms of grape poisoning include lethargy, vomiting, diarrhea, and blood in the urine. If you suspect that your Mastiff has eaten grapes, seek veterinary help immediately.


Yes! Mastiffs can eat mangoes.

Mangoes are a great source of vitamins A, B6, C, and E—and they also contain potassium and fiber. The antioxidants in mangoes can protect your Mastiff’s heart, brain, liver, kidneys and eyes from free radicals that cause cancer.

You should remove the skin and pits before feeding your Mastiff mango because they may cause choking or intestinal blockages.

Also, avoid processed mango products like mango sorbet, mango popsicles, and mango ice cream, as they may contain harmful preservatives or additives like xylitol (a sugar substitute commonly found in chewing gum). 

You can give your Mastiff a one-quarter cup of fresh ripe mango once a week.


Can a Mastiff eat oranges? The answer is yes!

Oranges are a great source of Vitamin C, potassium, fiber and moisture.

But you should only give your Mastiff the fleshy part of the orange, removing all traces of peel, skin, pith and seeds. You can give your Mastiff 1-2 sections as an occasional treat.


Yes, Mastiffs can eat peaches.

In fact, peaches are high in fiber and vitamin A, so they’re a healthy addition to your Mastiff’s diet. Small amounts of cut-up fresh or frozen peaches are safe for your Mastiffs to eat. Just remember to remove the pit before serving it to your Mastiff, as it contains cyanide.

Also, avoid processed peaches like peach cobbler or peach pie, as they may contain harmful chemicals and preservatives.


Can Mastiffs eat pears?

Yes, Mastiffs can eat pears. Pears are a great snack because they’re high in copper, vitamins C and K, and fiber. Eating the fruit can reduce the risk of having a stroke significantly, according to an article on AKC. Just be sure to cut pears into bite-size chunks and remove the pit and seeds first, as the seeds contain traces of cyanide. 

Also, avoid processed pears like canned pears as it may contain sugar syrups and other additives that aren’t good for your pet’s health. One small slice is ok for most Mastiffs as pears contain sugar.


Yes, your Mastiff can eat pineapple.

Pineapples are packed with vitamins and minerals, as well as bromelain, an enzyme that is beneficial for digestion. They also contain lots of moisture, which is good for Mastiffs who have dry skin or a dry nose.

However, you should only feed your Mastiff the soft inner fruit of the pineapple—not the hard outer core or any of the spiky leaves. You should also remove any leaves attached to the fruit before serving it to your pup.

You can give your Mastiff 2/3 small bites of raw pineapple per day if they like it. However, we recommend you to vary the treat for optimum health.


Yes, pure pumpkin itself is a great choice and a very healthy snack for Mastiffs.

Pumpkin helps with your Mastiff’s skin and coat, which can lead to fewer hot spots and other skin issues. It is rich in fiber, which can help remedy both diarrhea and constipation in your Mastiff by regulating their digestion.

But not just any pumpkin will do! Never feed your Mastiff pumpkin pie mix—it is full of sugar and preservatives that are entirely unnecessary for your pet’s diet. Instead, go with canned 100% pure pumpkin or even plain mashed pumpkin (which you can make at home). You can also find pumpkin supplements and Mastiff treats online if you don’t want to mess around with making your own treats.

The amount varies with your Mastiff’s size and activity level, but start with a teaspoon per day until you see how they do it.


Can Mastiffs Eat Strawberries?

Yes, your Mastiff can eat strawberries. They’re a great source of vitamins, minerals and antioxidants. But always cut the strawberries in small pieces before serving them to your Mastiff. Remove the stem, too—it can be hard on their digestive system.

Also, avoid processed strawberries as they may contain toxic chemicals.


Yes, Mastiffs can eat watermelon. Watermelon is a low-calorie treat that is rich in vitamins, minerals, and lycopene. It also contains moisture, which is great for hydration.

Only the flesh of a watermelon is a safe and nutritious part of the fruit for your Mastiff to eat. Cut it in small chunks so that it’s easy for them to chew and swallow. Remove seeds, rinds and skin before giving it to your Mastiff, as these parts are unsafe for them to eat. Half a cup of diced seedless and rind-free watermelon is enough per 10 pounds of body weight.

List of vegetable Mastiffs can or can’t eat

Wondering which vegetables your Mastiff can eat or not? Here is a list of some vegetables your Mastiff can or can’t eat:


Yes, broccoli is safe for Mastiffs to eat. It contains vitamin C, folate and vitamin K, but it’s not high in calories or protein.

Broccoli stems and florets, both are safe to eat, either cooked or raw. However, always cut them into small pieces so that they are less likely to cause a choking hazard. Offer 1/4 (0.25) cup of broccoli per 10 pounds of body weight of a pup.


Can Mastiffs eat cabbage? Yes, they can!

Cabbage contains vitamins, minerals and antioxidants. It is also rich in fiber and moisture. Red, green, all colors of cabbage are safe and healthy for Mastiffs. Even though red cabbage is more nutritious than green cabbage, both are safe to eat. Lightly cooked or roasted cabbage is the best way to offer it to your pup because it’s easy to digest. But make sure no seasoning with oil or salt when you cook it! Just one bite per 10 pounds of body weight is enough for your Mastiff to enjoy a nice treat.


Yes, Mastiffs can eat carrots.

Carrots are a great low-calorie treat for your Mastiff. They contain vitamins and minerals and fiber, so they’re good for their teeth and digestive system. 

You can feed them raw or cooked carrots—either is fine, though cooked carrots are better since they are easier for your Mastiff’s body to digest. If you’re going to feed raw or frozen carrots, chop them into smaller pieces so they don’t get stuck in their throat. Carrot cake is fine as long as you make it without harmful additives.

You don’t need to worry about giving your pup too many carrots—one or two baby carrots are enough for an average-sized pup.


Yes, Mastiffs can eat celery. It’s a great low-calorie treat that contains vitamins, minerals and antioxidants. It’s also high in moisture and fiber, which makes it a great snack for Mastiffs who are watching their weight or have digestive issues.

You can feed your Mastiff celery sticks or pieces of celery leaves as long as they’re organic and washed well.

However, it’s always best to cut the celery into bite-sized pieces before feeding it to your Mastiff so you can control how much he eats at one time (since celery can have laxative effects if eaten in large quantities).

Start with one or two bite-sized pieces and monitor how much he eats so you don’t overfeed him.


Yes, Mastiffs can eat cucumbers.

Cucumbers are a good source of vitamin B6, calcium and magnesium, as well as fiber and moisture. Cucumbers also provide phytochemicals that help freshen your Mastiff’s breath. The seeds and peels or skin are safe as long as they are organic.

However, avoid processed cucumbers like cucumber pickles, as they may contain harmful food additives like salt, sugar, etc.

How much you should feed your Mastiff depends on the size of your Mastiff, but only one or two pieces of cucumber are fine per day.


Can Mastiffs eat garlic?

The answer is no. Garlic is toxic to your Mastiff. It contains N-propyl disulfide, a sulfur compound that causes hemolysis and anemia in Mastiffs. Other symptoms include vomiting, diarrhea, abdominal pain, and even death. Raw and cooked cloves and bulbs of garlic are toxic to your Mastiff. The toxic dose is 15 to 30 grams of garlic per kilogram of body weight. Contact the vet immediately if your Mastiff ate garlic!


Can a Mastiff eat onions?

No. It is toxic to your Mastiff.

Onions contain N-propyl disulfide, a sulfur compound that causes hemolysis leading to anemia in Mastiffs. The toxic dose for an onion is 15 gm/kg of the body weight of your Mastiff.

Every type of onion can be dangerous to Mastiffs, including red, white and Vidalia onions. If your Mastiff ate any part of an onion plant—the flesh or leaves or even powder—it’s also likely they’ve eaten enough to be poisoned by it.

If you suspect your Mastiff has eaten an onion, contact your vet right away.


If you’re wondering whether your Mastiff can eat zucchini, the answer is yes. Zucchini is a low-calorie treat and full of vitamins and antioxidants. It’s also high in fiber and moisture that is good for your Mastiff’s digestive system.

However, there are some things to consider before feeding your Mastiff zucchini. 

First, raw zucchini provides more Vitamin A than cooked ones; so if your Mastiff has any issues with vitamin A, stick to cooked zucchini until you know more about their health needs. 

Second, start with just one or two small bites of zucchini at first—you don’t want to overwhelm your pup. Giving them too much at once because it can cause diarrhea or constipation.

List of some other snacks Mastiffs can or can’t eat

Wondering which snacks your Mastiff can eat or not? Here is a list of some snacks your Mastiff can or can’t eat:


Bacon is a delicious food for many humans, but it can be harmful to Mastiffs.

Bacon is an incredibly rich and fatty food with a high salt content, which can prove to be too much for a Mastiff’s stomach to handle. Eating a large amount can cause pancreatitis, an inflammation of the pancreas that often requires surgery and hospitalization. Bacon is also not good for Mastiffs because it contains nitrates and nitrites, which are preservatives that have been linked to cancer in humans.

However, giving your Mastiff small amounts of cooked bacon infrequently should not cause harm. In fact, some people feed their Mastiffs small amounts of cooked bacon as part of a balanced diet now and then.


Yes, Mastiffs can eat beef.

Cooked, unseasoned lean beef is safe for Mastiffs in small amounts unless your Mastiff is allergic to beef. It’s a good source of protein and many important vitamins and minerals. Beef broth, beef stew, and specialized Mastiff beef jerky without an excess amount of salt are also safe for your Mastiff.

Never feed cooked bone to your Mastiff, but larger raw beef bones can be a chew toy. For a 20 pounds pooch, one cup of kibble or 0.3 pound of ground beef is good if you opt for a raw diet.


Yes, your Mastiff can eat bread provided it’s not allergic to it.

However, only plain white and wheat bread is safe for Mastiffs to eat. Don’t offer them any other types of breads like rye or whole grain because these are not good for your Mastiff’s health.

Bread doesn’t provide that much nutrients in your Mastiff, so offer them in moderation. A crust is fine, but a whole slice is too much for your Mastiff. Too much bread can cause bloating, abdominal pain and diarrhea.


Yes, Mastiffs can eat cheese. A small amount of cheese is fine for your Mastiff. The important thing to remember is that not all kinds of cheese are good for your Mastiff. Mozzarella, cottage, swiss and cheddar cheese are safer options. Stay away from spicy cheeses like cheesecake, blue, goat, parmesan and cream cheese.

The amount of cheese you feed to your Mastiff will depend on the size of your Mastiff. A few small bites are fine, but don’t overfeed them.


Yes, Mastiffs can eat chicken. Chicken contains protein, omega-6 fatty acids, vitamins and minerals. Boneless cooked breast meat is the best option as it contains less fat than other parts of the chicken. Avoid chicken skin as it contains a high amount of fat that can cause diarrhea in your Mastiff.

The amount depends on the size of your Mastiff, but give 1/8 to 1/6 cup of meat protein per 10 pounds of body weight per day if your Mastiff is on a raw meat diet.


Can Mastiffs eat chocolate?

The short answer is no. Theobromine and caffeine are toxic to our canine friends, and can cause vomiting, diarrhea, hyperactivity, heart arrhythmias, and even death.

If your Mastiff ate chocolate, contact your vet immediately. There is no antidote for chocolate poisoning in Mastiffs, but treatment can help ease the symptoms.

Educate your family about the danger of chocolate in Mastiffs to prevent accidental ingestion.


Yes, your Mastiff can eat eggs!

Eggs are a good source of protein and fatty acids, as well as vitamins and minerals. They’re also rich in lecithin and choline, which help keep your pet’s organs healthy.

However, raw eggs may contain harmful bacteria that could make your Mastiff sick. It’s best to avoid them.

You should also avoid seasoning your Mastiff’s egg with salt or other spices that could be harmful to him. If you make sure the egg is cooked thoroughly with no spices or other additives, he’ll be able to enjoy it just fine.


Can Mastiffs eat fish?

The short answer is: yes! Fish is rich in protein, omega-3 fatty acids, vitamins and minerals, so it’s a great addition to your Mastiff’s diet. But not all fish are safe for your Mastiff. Smaller, younger, wild-caught, shorter-lived species like salmon and shrimp are safe for your Mastiff, but avoid longer-lived fish species like tuna, shark or swordfish as they can contain heavy metals like mercury. 

Always clean them properly before feeding them to your Mastiff—debone them and cook them thoroughly (no harmful additives), then feed your Mastiff one or two times per week in small controlled amounts.


Can Mastiffs eat ice cream?

Of course not! Ice cream is a dessert that contains high amounts of dairy products and sugar. If your Mastiff eats ice cream, they can become sick with symptoms like vomiting, diarrhea, weakness, lethargy, and even seizures. These symptoms are serious and should be treated immediately by a veterinarian.

Peanut butter

Yes, Mastiffs can eat peanut butter in moderation.

Peanut butter is a great source of protein, vitamins and healthy fats that your Mastiff needs to stay strong and healthy. However, make sure you’re buying pup-safe peanut butter without xylitol or chocolate. You also want to avoid peanut butter pretzels as they contain three times more sodium than regular peanut butter.

The amount you feed your Mastiff depends on the size of your Mastiff, but start with a half teaspoon per day.


Can Mastiffs eat popcorn? The answer is yes, but only in small quantities, and only if the popcorn has been air-popped.

Popped corn kernels actually contain several minerals important to Mastiffs, like magnesium, manganese, phosphorus, and zinc, along with fiber and trace amounts of vitamins. When you add butter or other toppings to the popcorn, however, you’re introducing fat into your Mastiff’s diet that can lead to obesity if he eats too much of it—which is why we recommend air-popping rather than popping in oil.

Buttered popcorn or popcorn with other toppings like cheese or peanut butter are not safe for your Mastiff. Even un-popped or partially popped kernels can be a choking hazard and may even cause damage to your Mastiff’s teeth if he chews on them for too long.


Yes, Mastiffs can eat turkey. Turkey is a great source of protein, fatty acids and minerals. It’s safe as long as you provide cooked lean, white, unseasoned and boneless turkey meat to your Mastiff.

Turkey breast meat is the best option. It provides your Mastiff with more protein than dark meat, which contains more fat. Avoid turkey skin and giblets since they can cause GI upset and pancreatitis in Mastiffs. Also avoid processed turkey since it may contain harmful chemicals that could make your Mastiff sick.

To calculate how much turkey to feed your Mastiff, multiply 20 grams of white meat turkey or 15 grams of dark meat turkey per 12 pounds body weight for your pooch.


Can Mastiffs eat yogurt?

Yes, Mastiffs can eat yogurt. Plain yogurt is a perfectly acceptable snack for Mastiffs. However, some Mastiffs may have trouble digesting dairy products. If your Mastiff can digest it, the good bacteria in yogurt can help strengthen the digestive system. Plain yogurt is the best choice for your Mastiff—avoid any yogurts with added sugar or artificial sweeteners as both of these can upset your Mastiff’s digestive system and make them sick. One teaspoon of yogurt a day is fine for most Mastiffs.
