Can dogs eat it?

Can dogs eat lettuce?

Yes, in moderation Yes. Plain lettuce is safe and mostly water. Do not share salad, which may contain onion or dressing.

Why

Romaine, iceberg and rocket (arugula) are non-toxic to dogs, low in calories and about 90% water (AKC), and Pet Poison Helpline lists lettuces among safe, low calorie foods. Too much can cause diarrhoea, and big leaves are hard to digest. Salads often contain onions, which are toxic.

How to give it safely

Wash it well and chop it rather than giving whole leaves, especially to small dogs or fast eaters.

This is general guidance, your vet sets the actual schedule. Puppies, small dogs and dogs with a health condition can react to smaller amounts. Check with your own vet before changing what your dog eats.

Other foods people ask about

Asparagus Yes, in moderation Yes, cooked and cut small. Raw spears are hard to chew and digest, and the asparagus fern in the garden is not safe. Aubergine (eggplant) Yes, in moderation Yes, a little plain cooked aubergine. The leaves and flowers of the plant are the parts to avoid. Beetroot Yes, in moderation Yes, a little plain beetroot, cooked or raw. Skip it if your dog has had bladder or kidney stones, and do not panic at pink wee. Bell peppers Yes, in moderation Yes, plain sweet peppers of any colour in small amounts. Never chilli or jalapeño peppers. Broccoli Yes, in moderation Yes, in very small amounts. Plain raw or steamed broccoli is fine, but too much irritates the stomach. Brussels sprouts Yes, in moderation Yes, a sprout or two, cooked and plain. More than that can cause wind and an upset stomach.
