Swiss chard is a leafy green beet relative with broad crinkled leaves and thick stems that may be white, red, yellow, or rainbow-colored. It is used sauteed, braised, added to soups, and folded into egg dishes. Plain cooked chard provides fiber, vitamin K, magnesium, and carotenoids.
The leaves and stems contain oxalates, which may be a concern for pets with a history of calcium oxalate urinary stones. Raw chard is also fibrous and may be harder to digest than cooked portions. Recipes often add garlic, onion, butter, cream, or cheese, which changes the safety profile.
Chard bunches are sold with long stems and large leaves that are often stored damp in produce drawers. Wilted leaves and trimming scraps can collect near kitchen prep areas. Discard trimmings promptly to limit unsupervised nibbling.
For pets, keep servings small, plain, and cooked until tender. Introduce slowly and monitor stool tolerance. Avoid seasoned side dishes and avoid routine use in pets with urinary stone history unless a veterinarian advises otherwise.
