Can dogs eat lettuce, and why?
Plain lettuce is a safe, low-calorie crunchy treat for dogs.
Dogs are omnivores, so most of their diet should be a complete, balanced dog food, with treats on top. They cope with a wide range of foods, but rich, fatty or sugary ones can cause stomach upset and, over time, weight gain or pancreatitis.
How to feed lettuce to dogs
- •How much: A few small pieces of washed lettuce; wash it well first.
- •How often: An everyday option in sensible amounts, but rotate with other foods for variety. Treats — including fruit and veg — should make up no more than about 10% of a dog’s daily calories.
- •Young pets: Puppies have more delicate tummies and specific growth needs, so introduce any new food in tiny amounts and check with your vet.
- •Preparation: Always wash fresh produce, remove any pips, stones, seeds, peel or tough skin where relevant, and serve it plain — never with salt, sugar, oil, butter or seasoning.
