Arugula is safe in small amounts but offers little nutritional benefit for pets. The bitter flavor may cause mild digestive upset if too much is given. Avoid dressed salad mixes, which carry oil, salt, and vinegar.
Arugula is a peppery leafy green from the mustard family with soft, lobed leaves and a flavor similar to radish or mustard. Baby arugula is milder; mature leaves are thicker and more pungent. It's a cool-season crop that bolts in summer heat.
Arugula is eaten raw in salads, used as a pizza topper, and added to sandwiches as a garnish. It's sold loose in bunches or in bagged spring-mix blends.
Arugula is commonly mixed with spinach, romaine, and other greens in spring-mix bags. Salad dressings and oils applied to mixed greens add fat and salt not suitable for pets.
