Why Holiday Table Foods Can Be Dangerous

Dogs and cats have digestive systems that aren’t built to handle rich, fatty, salty, or heavily seasoned holiday meals. Even small amounts can cause health issues such as:

1. Gastrointestinal Upset

Common symptoms include:

  • Vomiting
  • Diarrhea
  • Gas
  • Abdominal pain

Foods like bacon, butter, turkey skin, and garlic bread often trigger stomach upset.

2. Pancreatitis

High-fat foods—such as ham, gravy, buttery dishes, and fatty meats—can inflame the pancreas.
Symptoms include:

  • Repeated vomiting
  • Diarrhea
  • Painful or hunched posture
  • Lethargy
  • Loss of appetite
  • Fever

Pancreatitis can be life-threatening and may require hospitalization.

3. Toxic Reactions

Some foods are dangerous even in tiny amounts. Below are the most hazardous holiday foods for pets.

Common Holiday Foods That Are Toxic to Dogs and Cats

1. Chocolate (Dark, Milk, and White Chocolate)

Chocolate contains methylxanthines – such as caffeine and theobromine, which are toxic to pets.

  • Dark chocolate, baking chocolate and cocoa powder are the most dangerous.
  • White chocolate contains much less toxin but still isn’t safe.

Symptoms:

  • Vomiting
  • Diarrhea
  • Restlessness
  • Tremors or seizures

Why can’t dogs have chocolate? Their bodies cannot process theobromine, causing toxic buildup.

2. Xylitol

A sugar substitute found in sugar-free gum, candies, baked goods, and some types of peanut butter or almond butter.

Symptoms:

  • Sudden weakness
  • Vomiting
  • Tremors
  • Seizures

Xylitol can cause a life-threatening drop in blood sugar and liver failure.

3. Grapes & Raisins

Used in salads, desserts, breads, and holiday snacks.
Even a single grape  or raisin can cause kidney failure.

Symptoms:

  • Vomiting
  • Lethargy
  • Increased thirst
  • Kidney failure

Why can’t dogs have grapes? The exact toxin is unknown, but even tiny amounts can cause organ failure.

4. Onions, Garlic, Leeks & Chives (Allium Family)

Found in stuffing, casseroles, gravies, mashed potatoes, soups, and seasonings such as onion powder or garlic powder.

These foods damage red blood cells, causing anemia.

Symptoms:

  • Vomiting
  • Diarrhea
  • Pale gums
  • Rapid breathing
  • Weakness

Can dogs have onions, cooked onions, or garlic?
No—all forms are unsafe.

5. Alcohol (Including Raw Bread Dough)

Fermenting dough produces alcohol in the stomach, leading to toxicity.

Symptoms:

  • Disorientation
  • Vomiting
  • Weakness
  • Low body temperature
  • Seizures

6. Cooked Bones

Turkey bones, cooked beef bones, and ham bones splinter easily.

Risks:

  • Choking
  • Throat or stomach injury
  • GI blockage
  • Intestinal perforation

7. Fatty Meats, Skin, Butter & Gravies

These foods commonly trigger vomiting, diarrhea, and pancreatitis.
Items to avoid include:

  • Turkey bacon
  • Raw bacon
  • Lunch meat
  • Turkey skin
  • Butter-soaked dishes

8. Macadamia Nuts

Common in holiday cookies.

Symptoms:

  • Weakness
  • Tremors
  • Vomiting
  • Difficulty walking

9. Other Popular Holiday Foods to Avoid

  • Cranberry sauce (high sugar)
  • Garlic bread
  • Crab meat (often seasoned, high sodium)

Safe Holiday Treat Alternatives

If you want to include your pet in the celebration, offer:

  • Plain cooked turkey breast (no bones, skin, or seasoning)
  • A spoonful of plain mashed sweet potato
  • Steamed carrots, green beans, or brussel sprouts
  • Pet-friendly treats from your vet or pet store
  • A small amount of plain peanut butter (xylitol-free; ask: how much peanut butter can a dog have? — usually ½–1 tsp for small dogs, 1–2 tsp for larger dogs)

Holiday Food Safety Q&A

Can dogs have raisins?

No. Raisins are just dried grapes and are equally toxic.

How much chocolate can a dog have?

  • Has abdominal pain
  • Seems unusually lethargic
  • Shows tremors or seizures
  • Collapses

Early treatment is critical.
