Can Yorkies eat milk?
In tiny amounts, occasionally — a lick of plain milk won't poison a Yorkie, but many dogs are lactose-intolerant, so milk often causes gas, loose stools, or an upset tummy. It's not something a dog needs.
Dogs make less of the enzyme that digests lactose after they're weaned, so cow's milk commonly causes gas, diarrhoea, and stomach upset — more so in a tiny dog, where even a small amount is proportionally large. Milk isn't toxic, but it's fatty and offers nothing a complete diet doesn't already provide. Fresh water or the dog's normal food is a better choice. If you offer any, a small lick of plain, unsweetened milk is the limit; never flavoured, sweetened, or chocolate milk.
What Yorkie owners need to know
- Many dogs are lactose-intolerant and get gas or diarrhoea from milk.
- Milk is fatty and unnecessary — a complete diet already covers a dog's needs.
- Never offer flavoured, sweetened, or chocolate milk, and skip cow's milk for puppies.
How preparation changes the answer
| Preparation | Status | Why |
|---|---|---|
| Small lick of plain milk, healthy adult | Use caution | Not toxic, but often causes tummy upset — many dogs do better with none. |
| Flavoured, sweetened, or chocolate milk | Best avoided | May contain sugar, xylitol, or chocolate. |
Safe preparation
- If you offer any, use just a small lick of plain, unsweetened cow's milk — or better, skip it.
- Watch for gas or loose stools over the next day.
- Offer fresh water or the dog's normal food instead.
Portion for a Yorkie
At most a small lick of plain milk for a healthy adult 4-7 lb Yorkie, and only rarely; many dogs are better off with none.

Possible benefits
- Not toxic — a small accidental lick is unlikely to harm a healthy adult dog.
- Contains protein and calcium, though your dog already gets these from a complete diet.
- Plain is far safer than any flavoured or sweetened milk.
Risks & things to watch
- Lactose commonly causes gas, loose stools, or vomiting in dogs.
- Fatty for a tiny frame and adds unnecessary calories.
- Flavoured or chocolate milks can contain sugar, xylitol, or chocolate — all unsafe.
If your Yorkie ate too much
A little plain milk usually causes at most gas or loose stools that pass on their own. If your dog drank a lot, or any chocolate or sweetened milk, watch for ongoing vomiting or diarrhoea and call your vet — and treat chocolate or xylitol-containing milk as urgent.
Frequently asked questions
Why does milk upset my Yorkie's stomach?
Most dogs make less of the enzyme that digests lactose after they're weaned, so the milk sugar ferments in the gut and causes gas, loose stools, or an upset tummy. A small, lactose-sensitive dog feels it more.
Can Yorkie puppies drink cow's milk?
No — cow's milk isn't a substitute for their mother's milk or a proper puppy milk replacer, and it commonly causes diarrhoea. If a puppy needs supplemental feeding, ask your vet for the right formula.

Related foods
Cheese
In tiny amounts, usually yes — many Yorkies tolerate a small piece of plain low-salt cheese as a high-value treat, but it's fatty and some dogs are lactose-sensitive.
Plain Yogurt
In small amounts, usually yes — a spoonful of plain, unsweetened yogurt is fine for many Yorkies, but never a sweetened one, and watch for lactose sensitivity.
Cottage Cheese
Yes, in small amounts — plain, low-fat cottage cheese is usually well tolerated by Yorkies, but watch for lactose sensitivity and its sodium.
Butter
Use caution. Butter isn't toxic, but it is essentially pure fat with lactose, so even a small amount can upset a Yorkie's stomach or, in a susceptible dog, help trigger pancreatitis. It has no benefit, so it's best kept off the menu.
Cream Cheese
Use caution. A tiny amount of plain cream cheese isn't toxic, but it's high in fat and lactose, and flavoured tubs often contain onion, garlic, or chives. At most, a small smear of the plain kind — and check the label first.
Eggs
Yes — plain, fully cooked eggs with no salt, butter, or oil are a safe, protein-rich treat for Yorkies in small amounts.
