Puppies drink their mother's milk, but most dogs produce less lactase after weaning, so dairy can cause digestive upset. Milk is also high in fat and calories. Lactose-free milk is gentler but still unnecessary. Never give puppies cow's milk as a replacement for their mother's milk; use a puppy milk replacer if needed.
Yes, in moderation
A small amount is fine for most dogs, but it isn't needed. Many adult dogs are lactose intolerant, and milk can cause diarrhoea and gas. Water is the best drink; if you want to share, offer a few laps of plain milk and watch for loose stools.
This guide is general information, not a diagnosis. If your pet seems unwell, or you're worried, call your vet.
What you need to know
How to offer it safely
- Offer only a few laps, occasionally.
- Try plain yogurt or lactose-free milk if your dog seems sensitive.
- Avoid flavoured, sweetened or chocolate milk.
Treats, including human food, should make up no more than about 10% of your dog's daily calories. Our calorie calculator shows your dog's daily needs. Introduce any new food slowly and stop if it causes vomiting or loose stools.
