Keep your canine companion safe. This guide ranks dangerous foods from critical (requires immediate veterinary care) to moderate‑risk (avoid), explains symptoms, and offers a list of dog‑approved, nutritious snacks.


Critical Foods , Vet‑Immediately (Life‑Threatening)

# Food Why It’s Critical Typical Symptoms Immediate Action
1 Chocolate (dark, baking, cocoa powder) Theobromine & caffeine overload; dogs metabolize slowly Vomiting, diarrhea, rapid heartbeat, tremors, seizures, possible death Call vet NOW; provide wrapper for dosage info
2 Grapes & Raisins Unknown toxin → acute kidney failure Lethargy, vomiting, decreased urination, increased thirst Emergency vet; early IV fluids improve outcome
3 Onion / Garlic / Leek / Chive (raw, cooked, powdered) Sulfides cause hemolytic anemia Weakness, pale gums, vomiting, rapid breathing Contact vet; blood test may be required
4 Xylitol (sugar‑free gum, candy, baked goods) Massive insulin release → hypoglycemia & liver failure Drooling, weakness, loss of coordination, seizures, jaundice Immediate emergency care
5 Alcohol (beer, wine, spirits, fermented foods) CNS depressant; toxic dose is low for dogs Vomiting, disorientation, slowed breathing, coma Seek vet urgently
6 Macadamia Nuts Unknown toxin affecting muscles & nerves Weakness, tremors, hyperthermia, vomiting (usually resolves 24‑48 h) Call vet; monitor closely
7 Caffeine (coffee, tea, energy drinks) Same class as theobromine; overstimulates heart Restlessness, rapid breathing, arrhythmias, seizures Veterinary attention ASAP


High‑Risk (Urgent) Foods , Vet Soon

  • Cooked Bones , Splinter → choking or GI perforation. Symptoms: gagging, coughing, bloody stool.
  • Fat Trimmings / Greasy Foods , Can trigger pancreatitis. Symptoms: abdominal pain, vomiting, lethargy.

  • Avocado (pit & skin) , Persin may cause vomiting in some dogs.
  • Citrus peels , Essential oils irritate stomach lining.
