19 Sep 2025
 
Sharing food with your dog may feel like an act of love, but not everything on our plates is safe for them. In fact, some common human foods can be toxic even in small amounts. Knowing which foods to avoid is a key part of responsible pet parenting. 

At My Pet World, we’re committed to helping pet parents create safer, healthier lives for their furry companions. This guide lists the most common foods that are harmful to dogs, explains why they’re dangerous, and offers tips for keeping your pup safe.  

Why Some Foods Are Dangerous for Dogs
 
Dogs have different digestive systems and metabolisms from humans. A snack that seems harmless to us can cause anything from mild stomach upset to severe poisoning in dogs. That’s why it’s essential to be informed and cautious about what your dog eats. 

Foods That Are Toxic or Dangerous for Dogs:
 
1. Chocolate 
Chocolate contains theobromine and caffeine, both of which are toxic to dogs. Dark chocolate and baking chocolate are especially dangerous. Symptoms can include vomiting, diarrhea, restlessness, rapid breathing, and even seizures. 

2. Grapes and Raisins 
Even small amounts can cause sudden kidney failure in dogs. The toxic substance is still unknown, but the risk is high enough that these should never be fed. 

3. Onions, Garlic, Chives, and Leeks 
These foods can damage red blood cells, leading to anemia. Symptoms may include weakness, vomiting, and pale gums. Cooking doesn’t make them safer; they remain toxic. 

4. Avocado 
Avocados contain persin, which can cause vomiting and diarrhea in dogs. The pit also poses a choking hazard or risk of intestinal blockage. 

5. Alcohol 
Even tiny amounts of alcohol, including beer, wine, and food cooked with alcohol, can cause dangerous drops in blood sugar, blood pressure, and body temperature. 

6. Xylitol (Artificial Sweetener) 
Found in sugar-free gum, candy, and some peanut butters, xylitol can cause a rapid drop in blood sugar and, in severe cases, liver failure. Symptoms include weakness, vomiting, and seizures. 

7. Coffee, Tea, and Caffeine 
Caffeine stimulates the nervous system and heart in dogs, leading to restlessness, muscle tremors, and rapid heartbeat. In large doses, it can be fatal. 

8. Macadamia Nuts 
Just a few macadamia nuts can cause weakness, tremors, vomiting, and hyperthermia in dogs. 

9. Fatty Foods and Cooked Bones 
Greasy leftovers (like bacon or fried foods) can lead to pancreatitis, a painful and serious condition. Cooked bones may splinter and cause choking or internal injury. 

10. Raw Dough with Yeast 
Unbaked yeast dough can expand in a dog’s stomach, causing bloating, pain, and potentially dangerous complications.  

What to Do If Your Dog Eats Something Dangerous?

  • Stay Calm: Don’t panic, but act quickly.
  • Call Your Vet: Explain what your dog ate, how much, and when.
  • Emergency Care: In severe cases, take your dog immediately to a veterinary clinic.
