What foods are dangerous for dogs?

Many common human foods are toxic or dangerous for dogs. Here is a list of foods you should keep out of their reach:

• Chocolate: Contains theobromine and caffeine, which can cause heart arrhythmias, muscle tremors, and seizures. Darker chocolate and baking chocolate are the most dangerous.
• Grapes and Raisins: These can cause rapid kidney failure, even in small amounts.
• Onions, Garlic, and Chives: These can damage a dog's red blood cells, leading to anemia. This applies to raw, cooked, and powdered forms (often found in spice mixes).
• Xylitol (Birch Sugar): This artificial sweetener is found in many sugar-free gums, candies, and some peanut butters. It causes a dangerous drop in blood sugar and can lead to liver failure.
• Alcohol: Even small amounts can lead to severe intoxication, coma, or death.
• Macadamia Nuts: Can cause weakness, vomiting, tremors, and hyperthermia.
• Avocado: Contains persin, which can cause vomiting and diarrhea. The pit also poses a significant choking or obstruction hazard.
• Caffeine: Found in coffee, tea, and energy drinks; it can cause restlessness, rapid heart rate, and muscle tremors.
• Cooked Bones: These can splinter easily, causing choking or life-threatening punctures to the digestive tract.
• Yeast Dough: Raw dough can expand in a dog's stomach and produce alcohol as it ferments, leading to bloating and alcohol poisoning.

If you suspect your dog has eaten something dangerous, contact your veterinarian or an animal poison control center immediately.

Note: This is not an exhaustive list. If you are ever unsure about a specific food, it is safest to avoid giving it to your dog.
