Toxic Foods for Pets: Garlic, Onion, and Their Alternatives

Pet owners who feed their animals a natural diet — as well as owners of curious cats and dogs that love to taste everything — should know: onions and garlic are dangerous for pets. Just 5 grams of fresh plant per 1 kg of body weight can cause acute poisoning. These ingredients should never be added to your pet’s diet, and to prevent accidental ingestion, keep them stored in drawers or the refrigerator.
Why Are Garlic and Onion Dangerous for Pets?
Onions and garlic are common ingredients in many dishes. For humans, they can be tasty and even beneficial. But for pets, it’s the opposite: consuming these foods can trigger symptoms such as:
- Vomiting
- Difficulty breathing
- Weakness
These products contain thiosulfates — toxic compounds for animals that destroy red blood cells (erythrocytes). Ingesting onions and garlic can even lead to anemia. Therefore, they must not be given to pets in any form (raw, dried, or cooked), not even in small amounts.
Safe Alternatives to Garlic and Onion
When preparing a balanced natural diet for your pet, use flavorful and safe fresh alternatives:
- Celery — fresh taste with a crunchy texture.
- Dill — enhances flavor variety in dishes.
- Parsley — rich in vitamin C and iron.
- Basil — a source of vitamins, minerals, and antioxidants.
- Rosemary — improves digestion and is packed with antioxidants.
Remember: these herbs should only be given in moderation. Always check the ingredient list of pet food and treats to avoid harmful components.
If your pet has consumed onion or garlic, contact Animal Clinic immediately.
