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.
