Common Human Foods That Can Harm Your Dog's Health
Discover which common human foods can be dangerous for dogs, including chocolates, grapes, xylitol, and nuts. Learn safe dietary options from trusted brands like Royal Canin, Purina, and Hill's Science Diet to ensure your pet’s health and happiness.

While some human foods such as fish and milk are safe for dogs, others can pose serious health risks and trigger allergic reactions. Many pet owners are unaware of which foods to avoid, leading to accidental poisoning. To help you keep your furry friend safe, here's a guide to human foods that can be dangerous for dogs, including small breeds like Chihuahuas. Additionally, we recommend pet food brands like Royal Canin® and Purina® that offer nutritious, dog-friendly options.
Chocolate
Chocolate is highly toxic to all dogs, especially small breeds like Chihuahuas. It contains theobromine, a substance dogs cannot metabolize. Consumption can lead to vomiting, diarrhea, seizures, tremors, or even cardiac issues.
Xylitol (artificial sweetener)
Xylitol is found in sugarless gums, candies, mints, and baked goods. It can cause dangerous drops in blood sugar levels in dogs, particularly affecting smaller breeds. Foods containing xylitol include certain peanut butters, jellies, jams, and drinks.
Grapes and Raisins
These tasty treats can cause severe health issues for dogs, especially if ingested in large amounts. Accidental ingestion can result in kidney failure, vomiting, and lethargy. Keep grapes and raisins away from your pet's reach.
Macadamia Nuts and Walnuts
Though popular among humans, nuts can be toxic to dogs. Ingesting them may cause vomiting, diarrhea, tremors, and increased body temperature. Macadamia nuts are particularly harmful as they can inflame the pancreas.
Instead of risking your pet's health with harmful foods, consider trusted brands like:
