As a French Bulldog owner, you will know only too well how delicate their little stomachs can be. They are renowned for being sick after certain foods, and far more than other breeds might be.
Whilst it’s not always possible to keep your Frenchie from reacting badly to certain foods, you can still eliminate a lot of sickness by not letting them eat foods that are bad for French Bulldogs and their diet.
Please consider printing this list of bad foods off and stick it your refrigerator… some of the foods I list that your dog should avoid, aren’t just bad for your French Bulldog, they could even be fatal. Some will poison your dog and are foods that are toxic to French Bulldogs.
Because of this, I’ve put the most poisonous foods to French Bulldogs first on the list. It explains why they are toxic and even how much they might eat before you call a vet about your poorly Frenchie.
Bottom line though; if your French Bulldog eats anything they shouldn’t, don’t wait to read notes like this on the Internet – call your vet!
So, if you want to find out what food French Bulldogs can’t eat, plus some plants that are poisonous to them too – read on.
Poisonous foods for French Bulldogs
Like most dogs, French Bulldogs will eat whatever you put in front of them. If you happen to drop something on the floor and they gobble it up, in most cases, they should be fine with eating things in moderation.
Our own Frenchie Claude is like a garbage collector. He will vacuum anything that he comes across, so we need to be extra careful in the kitchen and dining room.
However, there are some foods that are extremely toxic and not safe for French Bulldogs to eat, even in small amounts. Knowing what French Bulldogs cannot eat is really important in keeping your dog safe.
Here’s the most dangerous foods for French Bulldogs, followed by things that they eat that are not poisonous as such, but are still bad.
This is most commonly misunderstood food that French Bulldogs cannot eat, and the one that leads to most people having to call a vet. You might think you are giving your Frenchie a tasty treat – but please don’t!
It’s all due to the toxic theobromine substance in chocolate. Just small amounts can make your French Bulldog sick, so if chocolate drops on the floor, pick it up immediately. In large amounts your Frenchie will vomit, and in more serious cases develop an abnormal heartbeat, tremors, seizure, and even death.
Dark chocolate is the most dangerous and poisonous to French Bulldogs as it contains more of the theobromine substance.
2. Onions, garlic, leeks and chives
All of these foods are in the Allium family. Anything in this bracket is a poisonous food for French Bulldogs, whether it’s been boiled, cooked, or whatever – it’s not something your French Bulldog should eat ever.
These foods are said to makes dogs feel poorly and in larger amounts can lead to red blood cell damage. You won’t always see symptoms of poisoning straight away as it can take a few days for the toxic effects to take effect.
3. Artificial sweetener (xylitol) in gum and mints
Xylitol is one of the most toxic things a French Bulldog could eat, and is commonly found in some mints and sugar-free gums. Avoid it at all costs.
According to research (see research published on MSU.edu), xylitol is 100 times more toxic than chocolate is for dogs. If they just eat one stick of gum with xylitol, a small dog could see their blood sugar levels dip considerably.
If a small dog went onto to eat a whole pack of gum with 10 sticks containing toxic xylitol, it could damage their liver irreparably and possibly even kill them. Be particularly careful around Frenchie puppies.
Other foods and household items that can contain xylitol include:
- Peanut butter
- Sugar-free candy
- Sugar free breath mints
- Fruit drinks
- Jellies and jams
- Baked goods
- Sugar-free puddings and Jello
- Over the counter vitamin supplements
4. Candy and sweets
It’s not just the foods above that come with toxic xylitol. Some candy brands do too, so always check the labelling.
To be frank, you shouldn’t be letting your Frenchie eat candy anyway, even if it’s free of poisonous xylitol. Why? It’s due to the sugar levels plus there’s also the risk of choking or blockages in your French Bulldog’s digestive tract or tooth fractures.
5. Certain peanut butter brands
Our French Bulldog loves peanut butter. It’s one of his favorite treats, especially when we put it in a Kong Toy.
However, some peanut butter brands include xylitol. This substance is toxic to dogs and needs to be avoided at all costs due to poisoning.
6. Corn on the cob
Corn on the cob is not among the poisonous foods for French Bulldogs, but it is dangerous due to the cob part. These can lodge in the throat of your dog and intestines, so should be avoided at all costs.
Sweetcorn is ok though, as this will be easily digestible though.
7. Cooked bones
Dogs love to eat bones. Everyone knows dogs love bones, but they are dangers with this food type.
When bones are cooked, they become brittle and can break apart. This means that when Frenchies eat cooked bones, small slithers can perforate their internal organs, leading to big risks to their health… with possible fatal consequences.
Fruit is a great food for French Bulldogs, but not all fruit! Avocado is one such, as it can be bad for French Bulldogs but only when prepared in a particular way.
Avocados contain a poisonous toxin called persin which when eaten in large quantities can lead to vomiting and diarrhea. However, persin is mostly concentrated in the avocado skin and pit, rather than the fleshy part.
So, should your French Bulldog eat an avocado, chances are you probably won’t have any problems. But it’s still worth avoiding, especially the toxic parts – the skin and stone.
9. Grapes and raisins
Another group of fruits that can be poisonous to your French Bulldog are grapes and raisins. They are a toxic food for French Bulldogs and can lead to kidney failure when eaten in large quantities.
10. Macadamia nuts and walnuts
All nuts should really be avoided in a French Bulldog’s diet, as they are just the right size and texture that lead to choking. However, these two nuts which are potentially toxic to dogs.
When eaten at volume, both can result in diarrhea, sickness, and the possibility of canine pancreatitis.
The side effects of Macadamia nuts are very nasty and rank high on the list of poisonous foods for French Bulldogs… the poisoning can result in hyperthermia, tremors, vomiting, and lethargy.
11. Cherry, peach, and plum pits
Due to the size of pips and seeds like this, they can become lodged in the intestines of smaller dogs like Frenchies. Blockages are a very real risk, so don’t let things like this anywhere near your dog’s mouth.
There are also trace elements of cyanide in the pits of some fruits like peach and plum. It would take a heck of a lot to poison your French Bulldog, but it’s a bad food either way.
12. Mustard seeds
Mustard is so vomit-inducing to French Bulldogs that vets sometimes use it to make dogs sick up for medical purposes. The seeds in particular are very toxic as they contain poisonous elements to dogs.
13. Coconuts and coconut oil
A little bit of coconut is unlikely to harm your French Bulldog, but the milk and white flesh of a coconut is known to cause stomach upsets in dogs.
The reasons coconut water should be avoided is due to the potassium in it, at high levels too.
14. Yeast dough
When ingested, yeast dough will heat up and then start to rise and create gas. This is very problematic in a French Bulldog’s digestive system, leading to extreme pain, bloating, and possibly the twisting of their gut.
It’s potentially fatal, so if your French Bulldog eats yeast dough, visit a vet immediately… the yeast can also change into ethanol, a highly potent alcohol.
This is good time to talk about alcohol dangers and how dangerous this drink can be for dogs.
Alcohol consumption can make your French Bulldog have diarrhea, vomit, difficulty in breathing, tremors, a lack of coordination, abnormal blood acidity, central nervous system depression, and even a possible coma or death.
Giving your dog alcohol isn’t funny and can kill them.
On a similar topic, the hops that are used in home brewing kits are also a dangerous ingredient for French Bulldogs to eat. There are compounds in the hops that lead to malignant hyperthermia.
That means your French Bulldog’s temperature can rise rapidly, possibly causing permanent damage to the organs and brain or even death.
17. Coffee, caffeine, and tea
Drinks with in are bad for French Bulldogs. It’s all down to the methylxanthines in the caffeine which causes similar bad reactions in dogs to chocolate.
If your French Bulldog has licked up a couple of coffee granules, chances are he will be fine. But in large amounts such as loose tea and coffee beans, it could be very harmful and require vet’s help.
Myristicin us a toxic substance with trace amounts found in nutmeg. When dogs eat it in large amounts it can lead to various problems including abdominal pain, increased heart rate, seizures, and even the possibility of hallucinations.
19. Moldy food
If your Frenchie has access to trash, be very careful. Moldy food is bad for French Bulldogs as it can contain mycotoxins. Mycotoxins grow on moldy food and make it poisonous when ingested.
Handy Hint: Here’s how you can help to secure your trash cans from your dogs so they don’t eat something that they shouldn’t.
Bad food for French Bulldogs
In addition to the foods that are bad for French Bulldogs, there are others. Whilst they are not strictly considered poisonous and toxic, you should avoid them due to the potential negative side effects. For example, weight gain.
20. Milk and dairy products
Many French Bulldogs will be lactose intolerant, meaning dairy products can make them sick. Dogs don’t have the same digestive system as us and can find it hard to break down lactose in milk, meaning runny diarrhea issues!
21. Blue cheese
Given that you know dairy is bad option for dogs, it should come as no surprise that some cheeses can be dangerous. Avoid the blue cheeses, Roquefort, and Stilton. They have roquefortine C which is known to cause very bad reactions in dogs.
This can include symptoms such as diarrhea and vomiting. In more extreme cases your French Bulldog could develop seizures and tremors if they eat a lot of blue cheese.
22. Meat and eggs that have not been cooked properly
Many owners now feed their French Bulldog a raw diet, and there’s nothing wrong with that providing they get all the nutrients and goodness required.
However, there is some research to suggest that bacterial infections such as Salmonella and E. coli can be contracted by dogs eating raw meat.
23. Food and drinks with high sugar content
Sugary food and snacks aren’t good for us, so they certainly aren’t for your dog. In fact, this is one of the worst foods for French Bulldogs, and can result in a range of health problems.
Dogs that have too many snacks with sugar content are at risk of developing diabetes, weight gain, and even decayed teeth and gums. Sugar can also upset delicate French Bulldog tummies too, so something to avoid at all costs.
24. Food high in salt and sodium content
Just like lots of sugar, the same applies to salt content. Food that is high in sodium can potentially poison your Frenchie… but is most likely to lead to them getting extreme thirst and increased urination in the volume it would be in dropped food.
If your French Bulldog does eat lots of salt, the warning signs are very severe and include vomiting, diarrhea, depression, tremors, high body temperature, and seizures.
25. Fatty foods
Fatty foods such sausage, bacon, burgers, and fried food can result in upset stomachs. If your French Bulldog gets to eat these tasty snacks over a prolonged period of time, it could even result in pancreatitis – don’t be tempted into letting your Frenchie eat even small amounts of junk, no matter how many times you hear about the McDonald’s dog friendly menu.
Yes, it’s hard to say no to those pleading eyes when they beg for your food, but often the tastiest food is the worst for French Bulldogs.
