Lettuce is safe for dogs

All common lettuce varieties (romaine, iceberg, butter lettuce) are safe for dogs. Lettuce is about 90% water, making it very low in calories. It's a decent treat for overweight dogs but provides minimal nutrition. Wash thoroughly and chop into small pieces to prevent choking.

Common Questions

Is iceberg lettuce safe for dogs?
Yes, iceberg lettuce is safe but it's mostly water with very little nutritional value. Romaine and leaf lettuce have more vitamins and minerals. All types are fine as an occasional snack.
Can lettuce cause diarrhea in dogs?
Large amounts of lettuce can cause loose stool due to its high water and fiber content. Start with small amounts and see how your dog handles it.

Plain lettuce is fine, but salads often contain ingredients that aren't safe — like onions, garlic, raisins, grapes, nuts, or dressings. Only feed plain, washed lettuce leaves.
