Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Lettuce (romaine, iceberg, rocket) is safe for dogs and is about 90% water, making it a hydrating, low-calorie snack similar to cucumber. Romaine lettuce is the most nutritious variety, offering some vitamin A, K, and folate. Iceberg lettuce has very little nutritional value but is not harmful. Unlike spinach or kale, lettuce is very low in oxalates, making it a safer everyday leafy green. Chop or shred into small pieces to prevent choking. Wash thoroughly to remove pesticides. Avoid salad dressings, croutons, and other salad toppings.
What You Should Know
Lettuce is generally considered safe for dogs to eat. As with any treat, moderation is key — it should complement a balanced diet rather than replace regular dog food. If your dog has never tried lettuce before, start with a small portion and keep an eye out for any unusual reactions.
