Can Dogs Eat Lettuce?
Short answer: Yes, plain lettuce is generally safe for dogs in moderation. Skip leftover salad and dressing.
Why it’s okay
The AKC says lettuce is generally safe in moderation. It’s about 90% water and low in calories. Romaine, iceberg and arugula are non-toxic. Its nutrition is fairly low, especially for iceberg, so it’s more of a crunchy snack than a nutrient source.
How much and how to serve it
Chop it up, especially for small dogs and gulpers, and wash it well.
Risks to watch for
- Too much can cause diarrhea.
- Lettuce has been recalled for E. coli and listeria contamination, so buy carefully.
- Leftover salads often contain onions or other toxic ingredients.
What to do if your dog ate lettuce
Most dogs only get a mild upset stomach from eating too much of a safe food. If your dog has vomiting, diarrhea or seems unwell, or if it ate a large amount, call your vet.
