Many human foods contain ingredients that are safe for people but can be dangerous or allergenic for dogs. Pet owners must be vigilant about what their furry friends eat to prevent adverse reactions. Some foods and herbs may cause mild to severe allergies or toxicity. Veterinary professionals recommend avoiding the following items in your dog's diet to keep them safe. Here's a rundown of these potential allergens.
Garlic and Chives
While garlic and chives may add flavor to human dishes, they are dangerous for dogs. Garlic particularly can damage their blood cells, increasing the risk of anemia. Certain breeds like Shiba Inu and Akitas are more sensitive to garlic's effects.
Black Pepper
Black pepper, while a common spice, can pose risks to dogs. Small amounts might not cause noticeable issues, but some breeds may experience severe reactions like respiratory problems or irritation. It's best to keep black pepper out of your dog’s diet to prevent discomfort.
Onion Products
Onions, including onion powder, are toxic to dogs. They contain compounds that damage red blood cells, leading to anemia and other blood disorders. Any form of onion should be avoided completely in canine diets.
Tarragon
Tarragon, known for its culinary uses, can be harmful to dogs. It contains estragole, a chemical that may cause liver issues and interfere with blood clotting, especially in pregnant dogs or those undergoing surgery. Avoid giving tarragon to your pets.
Marjoram
Marjoram is an aromatic herb similar to oregano, used in cooking and medicine. However, it can cause gastrointestinal problems such as vomiting and diarrhea in dogs. It is best to keep marjoram away from your pets’ food to prevent health issues.
