Can dogs eat lactose-free milk?

Quick verdict

In moderation

Recommended amount

A small amount occasionally as a treat; plain water remains the main drink.

Why

Lactose-free or special pet milk is easier to digest and fine for dogs in small amounts.

Can dogs eat lactose-free milk, and why?

Lactose-free or special pet milk is easier to digest and fine for dogs in small amounts. Still adds calories, so keep it to a treat; ordinary cow’s milk can cause upset.

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 lactose-free milk to dogs

  • How much: A small amount occasionally as a treat; plain water remains the main drink.
  • How often: An occasional treat, not a daily food. 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.
