Dogs Do NOT Tolerate Onions—This Shocking Danger Exposes the Risk When it comes to your beloved furry friend, not all human foods are safe. While many people share meals with their dogs, certain common kitchen ingredients—especially onions—pose a serious and often overlooked threat. Understanding why onions are toxic to dogs is crucial for every pet owner, as exposure can lead to serious health complications, sometimes even life-threatening poison. ### Why Do Dogs Not Tolerate Onions? Onions, along with garlic, leeks, and chives, belong to the allium family—plants that contain compounds like thiosulfate and N-propyl disulfide. These substances are highly toxic to dogs because they damage red blood cells, causing oxidative damage that leads to hemolysis (the breakdown of red blood cells). Unlike humans, dogs lack efficient enzymes to break down these compounds effectively, allowing toxicity to build up in their system.
