10 of the Worst Foods for Dogs

How to Feed Your Dog a Healthy Diet

We all want what’s best for our dogs. They’re not just pets—they’re family. To keep your dog safe and healthy, it’s important to know what foods to avoid and what nutritious options are out there. Let’s take a look at the worst foods for dogs and some healthier alternatives, including a few fresh dog food services that are making mealtime safer and smarter.

10 of the Worst Foods for Dogs

1. Chocolate

Chocolate contains theobromine, a compound that’s toxic to dogs. Even a small amount can lead to vomiting, diarrhea, rapid breathing, seizures and in severe cases, death. Dark chocolate is especially dangerous because it contains higher concentrations of theobromine.

2. Grapes and Raisins

Grapes and raisins can cause kidney failure in dogs, even in small amounts. Symptoms may start with vomiting and progress to lethargy and a lack of appetite. The exact cause of the toxicity is still unknown, so it’s best to avoid them completely.

3. Onions and Garlic

Whether raw, cooked, powdered or dried, onions and garlic are harmful to dogs. They can damage red blood cells and lead to anemia. Symptoms may not appear right away, but over time, they can become life-threatening.

4. Avocado

Avocados contain a toxin called persin, which can upset a dog’s stomach. While not always fatal, it can lead to vomiting and diarrhea. The large pit is also a choking hazard or can cause blockages in the digestive tract.

5. Xylitol

Xylitol is an artificial sweetener found in sugar-free gum, candy, baked goods and even some peanut butters. It causes a rapid drop in blood sugar in dogs, leading to weakness, seizures, liver failure or death.

6. Alcohol

Even a small amount of alcohol is dangerous for dogs. It affects the central nervous system, and can cause vomiting, difficulty breathing, tremors and in severe cases, coma or death.

7. Cooked Bones

Cooked bones can splinter easily and cause serious injuries to a dog’s digestive system. They can also pose a choking risk or lead to intestinal blockages. Raw bones may be safer, but should always be given with supervision.

8. Caffeine

Caffeine is found in coffee, tea, sodas and energy drinks. Dogs are much more sensitive to it than humans. Ingesting caffeine can lead to hyperactivity, increased heart rate, tremors or seizures.

9. Macadamia Nuts

These nuts are highly toxic to dogs. They can cause vomiting, tremors, muscle weakness and fever. The symptoms typically appear within 12 hours and can last up to 48 hours.

10. Fatty or Fried Foods

Greasy, fatty foods like bacon, sausage or fast food can cause pancreatitis, a painful condition that affects the digestive system. These foods are also linked to obesity and other long-term health issues.
