7 things your dog should NEVER eat 

Chocolate: Chocolate contains theobromine and caffeine, which are toxic to dogs and can cause vomiting, diarrhea, rapid breathing, increased heart rate, seizures, and even death. 

Grapes and Raisins: Grapes and raisins can cause kidney failure in dogs, leading to symptoms such as vomiting, diarrhea, lethargy, and decreased urine production. 

Onions and Garlic: Onions and garlic contain compounds that can damage a dog's red blood cells, leading to anemia. Symptoms may include weakness, vomiting, diarrhea, and pale gums. 

Xylitol: Xylitol is a sugar substitute commonly found in sugar-free gum, candies, and some baked goods. It can cause a rapid release of insulin in dogs, leading to hypoglycemia (low blood sugar), seizures, and liver failure. 

Avocado: Avocado contains persin, a substance that can be toxic to dogs in large amounts and may cause vomiting, diarrhea, and pancreatitis. The pit poses a choking hazard, and the high-fat content can lead to gastrointestinal upset. 

Alcohol: Alcohol is toxic to dogs and can cause intoxication, vomiting, diarrhea, difficulty breathing, tremors, and even coma or death. Keep alcoholic beverages out of reach of pets. 

Bones: Cooked bones, especially chicken and turkey bones, can splinter and cause choking, intestinal blockages, or perforations in a dog's digestive tract. It's best to avoid giving bones to dogs altogether.
