Quick answer: Yes, dogs can eat plain lettuce.
Do not feed your dog a full human-worthy salad with dressings and toppings that can be toxic. Also, keep in mind that dogs are omnivores and need a good deal more protein for optimal health, so a diet of just lettuce is not optimal.
Lettuce is a relative term that generally covers crisp leafy vegetables of many sizes, shapes, colors, and species. Salads and their fillings can literally be comprised of anything, we often call any mélange of ingredients a salad, but when they are lettuce based, this also covers a lot of ground. Lettuces come in many varieties, from tough and fibrous to buttery and soft, but are they safe for dogs to eat?
According to the American Kennel Club, these veggies get the OK in most cases. They say of the roughage, “Lettuce of the romaine, arugula, and iceberg variety do not contain anything that can really harm your dog. After all, it is 90 percent water. It’s also a low-calorie snack that could be a good training treat for an overweight dog.”
While the vegetable is safe for dogs to eat, but you still need to consider a few things before portioning off some for your pup:
- Salad Dressings: Store bought dressings rely heavily on garlic and onion powders to get that umami flavor we love, and the ingredients in anything you slather on salad may not be safe on many levels. Be sure to read labels, but know that some will just say ‘seasonings’ and that could be problematic. Feeding dogs lettuce that has dressing on it isn’t always a good idea.
- Salad Additions: We mentioned that onion and garlic are bad for dogs, but so are grapes that are often added into salads either fresh or in the form of raisins. Even avocados can cause some reactions even if just smeared on some lettuce. Refresh your memory of which foods aren’t dog safe regularly to avoid issues like stomach problems and allergic reactions.
- Cleanliness: Like any food you feed your dog, cleanliness is just as important for their digestive system as yours. Lettuces can become contaminated and need to be cleaned well before use. This sometimes can unfortunately happen to pre washed bagged lettuces as well, so be on the lookout for recalls.
- Overdoing it: Aside from raw greens being mostly safe if eaten in moderation, too much fiber can be bad for a dog who isn’t accustomed to it. Additionally, dogs can encounter health issues from consuming too many dark leafy greens like spinach, kale, chard, and collards, which have irons and calciums that aren’t ideal for dog stomachs. Keep it to small portions for less gastrointestinal stress.
Dogs can eat lettuce right alongside you, but be sure that it’s unseasoned and without any unfriendly “accessories.” Make sure it’s clean, and keep it in moderation.
