The holidays bring festive meals, crowded kitchens, and plenty of opportunities for pets to sneak a bite. While sharing food may feel harmless, veterinarians and animal toxicology experts consistently warn that certain holiday foods can cause serious — and sometimes life-threatening — reactions in pets.
Below is a calm, preventative guide to holiday foods pets should avoid, with clear species notes and light, authoritative attribution to trusted veterinary sources.
1. Chocolate (Dogs & Cats)
Chocolate contains theobromine and caffeine, stimulants that pets cannot metabolize efficiently. Dogs are most commonly affected, but cats are also vulnerable.
Possible symptoms may include:
Vomiting or diarrhea
Restlessness or rapid breathing
Elevated heart rate
Tremors or seizures in severe cases
Veterinary toxicology resources from the ASPCA Animal Poison Control Center consistently list chocolate among the most frequent pet toxins reported during holidays.
Note: Even small amounts may cause problems, particularly dark or baking chocolate.
2. Turkey Bones & Fat Trimmings (Dogs & Cats)
Cooked poultry bones can splinter, increasing the risk of choking or internal injury. Fatty trimmings and skin may irritate the digestive system and are associated with pancreatitis, a painful inflammatory condition.
Veterinarians generally caution that rich, fatty foods — especially when eaten suddenly — may increase pancreatitis risk, particularly in dogs.
3. Onions, Garlic & Chives (Dogs & Cats — Higher Risk in Cats)
Members of the Allium family (onions, garlic, leeks, chives) are toxic in raw, cooked, powdered, or dehydrated forms.
According to ASPCA, ingestion of Allium plants may damage red blood cells and can lead to Heinz body hemolytic anemia, with cats considered especially sensitive.
Signs may include:
Weakness or lethargy
Pale gums
Rapid heart rate
4. Grapes, Raisins & Fruitcake (Dogs Only)
Grapes and raisins are toxic to dogs and have been linked to acute kidney failure. The exact toxic mechanism is still under investigation, which means no safe amount has been established.
The ASPCA Animal Poison Control Center advises immediate veterinary attention if ingestion is suspected — even if symptoms are not yet visible.
5. Alcohol & Raw Dough (Dogs & Cats)
Alcoholic beverages and foods containing alcohol can depress the central nervous system. Raw yeast dough poses an additional risk because it may expand in the stomach and produce ethanol as it ferments.
Veterinary emergency references, including the Merck Veterinary Manual, note that these exposures may lead to:
Disorientation
Vomiting or bloating
Low body temperature
Respiratory distress in severe cases
6. Xylitol (Dogs Only)
Xylitol is a sugar substitute found in sugar-free desserts, gums, and baked goods. In dogs, it may cause rapid hypoglycemia and has been associated with acute liver failure.
Both the ASPCA Animal Poison Control Center and the U.S. Food and Drug Administration list xylitol as a high-risk exposure for dogs.
Important: Xylitol toxicity is a dog-specific concern; cats do not appear to be affected in the same way.
7. Rich Gravies, Buttery Sides & Cheese Platters (Dogs & Cats)
High-fat foods can overwhelm a pet’s digestive system. While not always toxic, overconsumption may result in vomiting, diarrhea, bloating, or pancreatitis — particularly in dogs with a prior history of digestive sensitivity.
Veterinarians generally recommend keeping treats minimal and offering plain, unseasoned alternatives if sharing food at all.
When to Act
If your pet eats any of the foods above — or you’re unsure what they consumed — contact your veterinarian immediately or call the ASPCA Animal Poison Control Center (888-426-4435). Prompt guidance can significantly affect outcomes.
