Chocolate includes methylxanthines, which are harmful stimulants that inhibit a dog's metabolism. Even a little chocolate, especially dark chocolate, can trigger diarrhea and vomiting.
Avocados
Every part of the fruit contains persin, a fatty acid that is harmful to dogs in big amounts. Avocado goes well on most things, but not puppy chow.
Onions and Garlic
People eat a lot of these vegetables, but they can kill your dog's red blood cells and give her anemia. It's bad for her health to do even a little bit.
Grapes and Raisins
Dogs run the risk of developing renal failure if they consume this seemingly harmless fruit in either its fresh or dried form. Holy cow!
Milk and other Dairy Products
A dog can only drink milk from its mother. Any other kind of dairy, like cow, goat, or sheep milk, could make it sick. Some sugars and fats are hard for dogs to digest because they lack the enzymes needed to do so.
Macadamia Nuts
It's unknown what makes these nuts deadly to dogs, but they are. Your dog may want your macadamia nut cookie, but don't give in. Maybe he'll thank you later.
Sugary foods and drinks
When we talk about cookies, don't give your dog any foods that are high in processed sugars. When people eat too much sugar, they gain weight, get cavities, and even get diabetes. The same will happen to her.
Caffeine
It is dangerous for dogs to consume because it is a stimulant. Even while you may look forward to your morning coffee, you shouldn't give your dog anything other than plain old water.
Yeast dough
Raw food might fester in your dog's stomach. Fermentation can produce alcohol poisoning, and rising will hurt your dog's stomach. Avoid feeding your dog leftover pizza dough next time you cook one!
Salt
Too much salt can make you thirsty and even hurt you with sodium ions. A small amount of salt is fine, but watch how much your dog eats to keep the amount at a minimum.
