- Xylitol (in sugar-free products) can be lethal in tiny amounts — check all peanut butter labels
- Grapes and raisins cause kidney failure; no safe dose exists — even one grape can be dangerous
- Chocolate, onions, garlic, macadamia nuts, and alcohol are all toxic to dogs
- Cooked bones splinter and cause internal punctures — never give cooked bones
- If exposure happens: call ASPCA Poison Control (888) 426-4435 or your vet immediately

Deadly — Can Kill Your Frenchie
| Food | Why It's Dangerous | Toxic Amount |
|---|---|---|
| Xylitol (birch sugar) | Causes rapid insulin release leading to fatal hypoglycemia; can cause liver failure | Even tiny amounts — found in sugar-free gum, candy, peanut butter, toothpaste, baked goods |
| Grapes & Raisins | Causes acute kidney failure. Mechanism unknown — impossible to predict toxic dose | Even one grape can be dangerous. No safe amount exists. |
| Chocolate | Contains theobromine and caffeine — toxic to dogs. Dark/baker's chocolate most dangerous. | Dark chocolate: ~1 oz per lb is dangerous. Milk chocolate: ~3 oz per lb. |
| Onions & Garlic | Destroys red blood cells (hemolytic anemia). All forms — raw, cooked, powder, dehydrated. | Onions: 0.5% of body weight. Garlic: more potent — even small amounts regularly. |
| Macadamia Nuts | Causes weakness, vomiting, tremors, hyperthermia. Mechanism unknown. | As few as 6 nuts can cause symptoms |
| Alcohol | Ethanol is rapidly absorbed — causes vomiting, disorientation, respiratory failure | Very small amounts due to low body weight of Frenchies |
Dangerous — Can Cause Serious Harm
| Food | Risk | Notes |
|---|---|---|
| Cooked bones | Splinter and can puncture intestines or cause blockage | Raw bones are safer but still supervised only |
| Avocado | Contains persin — causes vomiting and diarrhea. Pit is a choking/blockage hazard. | Flesh is mildly toxic; pit and skin are worse |
| Caffeine | Same toxin family as chocolate. Coffee, tea, energy drinks. | Causes restlessness, rapid breathing, heart palpitations |
| Raw yeast dough | Expands in stomach causing bloat; yeast produces alcohol as it ferments | Double danger: bloat + alcohol toxicity |
| Nutmeg | Contains myristicin — causes hallucinations, increased heart rate, seizures | Even small amounts in baked goods can be problematic |
| Salt (excessive) | Sodium ion poisoning — causes vomiting, diarrhea, seizures, death | Chips, pretzels, salted snacks. Also salt dough ornaments. |
Harmful — Cause Digestive or Other Issues
| Food | Problem |
|---|---|
| Dairy (milk, cheese, ice cream) | Most Frenchies are lactose intolerant — gas, diarrhea, stomach upset |
| Fatty/fried foods | Can trigger pancreatitis — painful and potentially life-threatening |
| Corn on the cob | Corn itself is OK, but the cob causes intestinal blockage if swallowed |
| Cherries, peaches, plums | Flesh is OK in small amounts, but pits contain cyanide and are choking hazards |
| Raw eggs | Salmonella risk; avidin in raw egg whites can interfere with biotin absorption |
| Raw fish | Can contain parasites; some raw fish (salmon) can carry fatal Neorickettsia |
| Spicy foods | Causes stomach upset, diarrhea, and pain — Frenchies' stomachs are already sensitive |
Common Allergens (Not Toxic, But Cause Reactions)
These foods aren't poisonous but commonly trigger allergic reactions in French Bulldogs:
- Chicken — The #1 food allergen in Frenchies
- Beef
- Wheat and grains
- Soy
- Eggs
- Corn
See our Allergies Guide for detailed information on food allergy diagnosis and management.
Safe Human Foods for Frenchies
Not all human food is bad! These are safe in moderation:
- Carrots — Low calorie, good for teeth, high in vitamin A
- Blueberries — Antioxidant-rich superfood
- Apple slices (no seeds or core) — Fiber and vitamins
- Plain cooked chicken (if no allergy) — Lean protein
- Pumpkin puree (plain) — Digestive support
- Watermelon (seedless, no rind) — Hydrating, low calorie
- Green beans (plain, cooked) — Low-calorie filler for weight management
- Sweet potato (cooked) — Fiber, vitamins
- Banana — Potassium, fiber (high in sugar — small amounts only)
- Plain cooked rice — Gentle on upset stomachs
Human food treats should never exceed 10% of your Frenchie's daily calorie intake. Even safe foods can cause weight gain and nutritional imbalance if overfed.
