Garlic is significantly more toxic to dogs than onions on a per-gram basis. It damages red blood cells and causes haemolytic anaemia, leading to weakness, pale gums, and jaundice. Even small amounts can trigger serious symptoms. Dogs that consume garlic require immediate veterinary attention. Prevention is essential: keep all garlic away from your dog, including cooked garlic in sauces and prepared foods. If accidental ingestion occurs, contact your vet immediately with the amount consumed and your dog's weight.
