Onion Powder
Onion powder is a concentrated form of onion and is even more dangerous to pets than fresh onion because a small volume contains a large dose of toxins. It appears in many processed human foods, including broth, sauces, snacks, and seasoning blends. Toxicity affects the red blood cells, leading to anemia that can be life-threatening if untreated.
