- 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
1. Stay calm. 2. Identify what they ate and how much. 3. Call your vet or the ASPCA Animal Poison Control Center: (888) 426-4435 (US, $95 consultation fee) or Pet Poison Helpline: (855) 764-7661. 4. Do NOT induce vomiting unless specifically told to by a professional. 5. Go to the emergency vet immediately if instructed.
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 (BMC Veterinary Research, 297 dogs):
- Beef (34%) — the #1 food allergen in dogs
- Dairy (17%)
- Chicken (15%) — very common in cheap kibble, frequent trigger
- Wheat (13%)
- Soy (6%)
- Eggs (4%) / Corn (4%)
- Fish (2%) — lowest allergy risk, safest protein for Frenchies
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.
