5 Foods You Shouldn't Give to Your Dog

Chocolate contains theobromine and caffeine, which are stimulants that are toxic to dogs. Dark chocolate and unsweetened baking chocolate have the highest levels of theobromine and are particularly dangerous. Consumption can lead to symptoms like vomiting, diarrhea, increased heart rate, seizures, and, in severe cases, death.

Grapes and raisins can cause kidney failure in dogs. Even a small amount can be toxic. Symptoms may include vomiting, diarrhea, lethargy, and abdominal pain.

Onions and garlic, whether raw, cooked, or in powdered form, can damage a dog's red blood cells, leading to anemia. Symptoms include weakness, vomiting, and difficulty breathing. Garlic is generally more potent than onions, but both should be avoided.

Xylitol is an artificial sweetener commonly found in sugar-free gum, candies, and certain baked goods. It can cause a rapid release of insulin in dogs, leading to hypoglycemia (low blood sugar), seizures, and even liver failure. Xylitol is extremely toxic to dogs, and even small amounts can be life-threatening.

Cooked bones, especially those from poultry or fish, can splinter and cause internal injuries or blockages in a dog's digestive system. They can also pose a choking hazard. It's generally safer to provide specially designed dog bones or treats rather than leftover human food bones.
