Dogs can eat spinach, but only in small amounts and preferably cooked rather than raw. Spinach is nutritious, containing vitamins A, B, C, and K, iron, antioxidants, and fiber. However, it contains oxalic acid, which in large quantities can interfere with calcium absorption and potentially cause kidney damage or bladder stones. Therefore, spinach should be fed occasionally and in moderation, avoiding canned spinach due to its high sodium content. It is important to prepare spinach plain without butter, oil, onions, or garlic, which are harmful to dogs. Dogs with kidney problems should consult a vet before consuming spinach. Raw spinach is harder for dogs to digest, so steaming or blanching is recommended. Overall, spinach can be a healthy occasional treat for dogs but should not form a large part of their diet.
