Guide: The Ultimate List of Fruits That Your Dog Can't Eat

One of those endearing traits our pups have is those big round eyes looking up at us when we're eating, begging for a bite of whatever's on our plates. They'll happily hoover up just about anything that comes their way, but we all know that isn't always good for them.

The things we eat as people aren't always the things our canine companions can eat. Just like how there are plenty of foods that are toxic to cats, there are human foods our dogs shouldn't eat either. What should you keep off the menu to avoid giving your pooch a hard time?

Can Dogs Eat Fruit?

First, a simple question: can dogs eat fruit at all? Fortunately, the answer is yes. While dogs aren't obligate carnivores like cats, they do have some dietary restrictions, largely related to certain chemicals that can give them a bad time.

Dogs can enjoy fruits as treats. Fruits like apples, blueberries, pears, strawberries, watermelon, mango, and others are all good options. My guide (linked right there) can give you some great ideas on which fruits to use, and how to use them.

What Makes a Fruit Bad for Your Dog?

Some fruits are going to be bad for your dog, but why are they bad? Are they full of chemicals that are fine for humans but toxic to dogs? Are they going to trigger an allergic reaction?

Generally, there are three main reasons that can disqualify a fruit from being part of your dog's diet.

The first reason is sugar. A lot of fruits are considered fairly healthy, but they're full of natural sugars. Natural fructose is better for you (and your dog) than artificial sugars, and it's way better than chemical sweeteners like xylitol, which can be toxic to your dog. But, it's still a lot of sugar, which can cause problems with obesity and diabetes, especially in older dogs.

The second reason is something that could choke your dog. Fruits that have large seeds or pits can be obstructions and, depending on the size of your dog, can block their airway or their bowels. Both of these can be very dangerous and painful to your pup.

On that note, it's a good idea for any canine caregiver to know how to help a choking dog because time is of the essence. Check out this guide to the canine Heimlich Maneuver to learn more.

Some of these fruits are fine if you prepare them right, while others might have other reasons to avoid them as well. I'll get to that in the actual list.

The third reason is toxicity. Some fruits do, in fact, have toxic compounds in them. At best, these can cause bowel upset or vomiting. At worst, they can become a life-threatening medical issue. It's better to avoid them entirely.

Now, let's go through the list.

Fruits a Dog Shouldn't Have Because of Toxic Ingredients

First, let's talk about the fruits that your dog absolutely shouldn't have. Any fruit with toxic compounds in it should be avoided entirely.

Avocados

Avocados are often thought of as vegetables, but they're actually fruits. They also fit both the toxicity and the obstruction points because the pit of the avocado is tough and can be a choking hazard.

The most important part, though, is that avocado skins, pits, and leaves all contain a compound called persin. While persin generally won't kill a dog unless it's very small and they eat a lot of it, it's going to cause gastrointestinal distress, including vomiting and diarrhea. That, combined with the high-fat flesh of the avocado, makes for a bad time for everyone.

Persin can also cause pancreatitis if consumed in sufficient amounts or over a long term.

Note that you can still use products like dog fur conditioners that include avocado oil; these ingredients have been refined to remove anything toxic. Since avocado oil is a great way to add luster and shine to your dog's coat, many people still use the fruit, even if it's not for eating.

Cherries

Cherries are a fruit that really hits all three of the reasons why a dog shouldn't have them.

They're pretty sweet and sugary, especially sweet cherries (tart cherries are a little less so, though they do still have a lot of sugar in them.)

They have pits. Those pits aren't going to bother a larger breed, but small dogs might choke on them.

Most importantly, though, they contain cyanide in the pits.

If you carefully pit cherries and give them to your dog in moderation, it's probably fine that they have one or two here or there. If you have a cherry tree, though, make sure your dog can't go to town on fallen fruit. The same goes if you eat cherries; make sure your pup can't fish the pits out of the trash.

It's also a good idea to learn the signs of cyanide poisoning. Dilated pupils, difficulty breathing, and red gums can all be signs.

Grapes

One of the worst fruits for dogs, grapes of all sorts are bad for our canine friends. Grapes (and raisins) are so toxic to dogs that they can cause sudden kidney failure in surprisingly small quantities. Just keep them away from your dog at all costs.

This is a good place to discuss the symptoms of poisoning in dogs. If you're worried that your dog might be poisoned or ate something they shouldn't that could hurt them, look for symptoms like:

• Bowel issues, including constipation and diarrhea.

• Lethargy and delayed responses.

• Standing with their back hunched.

• Twitching or seizures.

• Vomiting, drooling, or foaming at the mouth.

These symptoms indicate an emergency, and you should rush your pup to the emergency vet ASAP to get treatment before their organs shut down. Your vet will administer treatment like activated charcoal, a medication to induce vomiting, and scans or even surgery to address what's wrong. Obviously, it's better to keep the grapes (and other toxic fruits) out of reach.

Green Tomatoes

Tomatoes are part of the same overall plant family as nightshade, so it's not really a surprise that it can be toxic to some animals.

Fully ripe tomatoes are fine for dogs, but under-ripe or green tomatoes, as well as the green parts of the plant, all contain a chemical called solanine. That chemical is only mildly toxic, so your dog would probably have to eat a whole tomato plant or more to get really sick over it, but it's still better to avoid it, wouldn't you say?

Plums

Plums are another fruit where the pit contains cyanide and can be a choking hazard. Basically, any stone fruit is going to have these issues since they're all similar.

The flesh is fine, but the pits are very dangerous, so you have to be careful with how you dispose of them.

Raspberries

Raspberries are right on the fence. They're a healthy fruit and they're undeniably delicious, but they do contain a very small amount of xylitol.

One or two isn't going to be enough to hurt a dog unless they're very, very small or are very sensitive, but a whole package of raspberries – or a dog left to their own devices next to berry bushes – can cause problems quite quickly.

Fruits a Dog Shouldn't Have Because of Obstructive Elements

The second group is fruits that should either be avoided or be prepared properly if you want to give them to your dog. That's because they contain something, like a pit, a core, or seeds, that can block airways or obstruct bowels if your dog swallows them. Avocados, already listed above, fall into this group because of the pit as well.

Peaches

Peaches are a good example of a fruit that can be fine in moderation for dogs, but can also be very high in sugar, and the pit is dangerous.

Not only is the pit capable of blocking an airway, but it also contains a chemical called amygdalin, which, when digested, creates cyanide. So, why didn't I list it in the toxic section? The edible part of the fruit is fine.

Oranges

Oranges aren't bad for your dog, but vets generally recommend leaving off the skin and removing the seeds when possible. By the time you're done doing that, it's practically not worth it for a treat anymore, right?

That said, some dogs don't like citrus at all because the citrus oils are very strongly scented, and your pup's sensitive nose might be irritated at having them close. If you ever peel an orange and notice your pup avoids you, that's probably why.

Other citrus all fall into this category as well. Lemons, limes, grapefruits, pomelos, mandarins, citrons, tangerines… the list goes on. Relatedly, did you know that all citrus we enjoy today are cross-breeds and hybrids between three original citrus plants? Mandarins, Pomelos, and Citrons are the three originals; everything else is some manner of derived hybrid between them.

Persimmons

Persimmons are a less common fruit, but the seeds they contain can be obstructive to your dog's bowels. They aren't super toxic, which is why they aren't listed in the toxic list, though they do contain compounds that can cause digestive upset.

Under-ripe persimmons are also very astringent and can also cause digestive upset. The flesh of the ripe fruit is fine in moderation, though.

Fruits a Dog Shouldn't Have Because of Excessive Sugar

Finally, let's talk about some fruits you should consider avoiding. These aren't necessarily dangerous for your dog, but they are high in sugar. That means if they have diabetes, or you're worried about obesity or them developing diabetes down the line, it's better to avoid them. They can be given in moderation, though; a single bite here and there, as a high-value treat, can be just fine.

Bananas

Bananas are emblematic of this entire category. They're very sweet and have a ton of sugar in them when they're ripe, but they also have a lot of healthy minerals and vitamins that your dog will enjoy.

A slice of banana tossed to your pup with you eating one yourself is fine, but they shouldn't be part of their primary diet.

Canned Fruits

I'm not specifying one particular fruit here. Many canned fruits are canned with added sugar or even syrup, and that's a huge hit of sugar your dog doesn't need. Obviously, if the canned fruit is one with another issue, you have twice the reason to avoid it.

Note that even fruits canned in water or juice still tend to have added sugar to them. Syrup is worse, but juice isn't always better.

Dangerous Fruits for Dogs FAQ

As usual, let's wrap things up with a few common questions.

What should I do if my dog ate a bad fruit?

This depends on the fruit. Grapes? Take them to the vet ASAP. Other fruits? Keep an eye on them. If they exhibit the symptoms of poisoning, take them to the vet. Otherwise, just keep an eye out for obstructions and be prepared for a messy bathroom break.

Fruits that are high in sugar are only bad for weight and diabetes reasons, so if your dog is otherwise healthy, a bit of over-indulgence won't hurt them. Just don't make it a regular thing.

How can I get rid of pits and seeds?

Many people recommend a dog-proof trash can for things you really don't want your dog to get into. I've known some very clever dogs that find their way into these, though, so make sure whatever you get can resist the cleverest pupper around.

Alternatively, make sure to store the waste out of their reach until you can get rid of it.

What is the worst fruit for dogs?

Undoubtedly, grapes. It's actually kind of crazy that we don't even know which compounds in grapes are the toxic ones, but we know that all kinds of grapes, even in small amounts, can lead to very sudden kidney failure and even death.

If your dog even eats just one grape, you should be extremely vigilant for signs of poisoning and call your vet ASAP.
