# Can Dogs Eat Yoghurt UK?

**Plain, unsweetened live yoghurt is usually safe in small amounts.** Avoid flavoured, sweetened, or "low-fat" products — they may contain **xylitol**, which is toxic to dogs. Some dogs are lactose intolerant; stop if diarrhoea develops. Yoghurt is a treat, not a meal replacement.

## Plain yoghurt — usually fine

Plain live yoghurt with **no added sugar, sweeteners, or flavourings** is generally safe as an occasional treat. Greek yoghurt is lower in lactose and often better tolerated.

Benefits are modest — probiotics may support gut health, but evidence in dogs is limited compared to complete diets.

## Critical: check for xylitol

**Never feed "sugar-free" or "low-fat" yoghurt** without reading the label. Many contain **xylitol**, an artificial sweetener that causes life-threatening hypoglycaemia and liver damage in dogs.

If your dog ate xylitol-containing yoghurt, phone your vet or **Animal PoisonLine (01202 509000, charges apply)** immediately. See [xylitol poisoning](/health/xylitol-poisoning-in-dogs).

## Lactose intolerance

Some dogs lack sufficient lactase enzyme and develop diarrhoea or wind after dairy. Introduce yoghurt gradually and stop if gut upset occurs.

## What to avoid

| Product | Risk |
|---------|------|
| **Flavoured yoghurt** | Sugar, artificial sweeteners |
| **Low-fat / diet yoghurt** | May contain xylitol |
| **Yoghurt with fruit pieces** | Grapes or raisins are toxic |
| **Frozen yoghurt** | High sugar; possible xylitol |

## How much is enough?

A teaspoon for small dogs or a tablespoon for larger breeds, occasionally. Too much causes digestive upset regardless of lactose tolerance.

## FAQs

### Can dogs eat yoghurt?

Plain, unsweetened live yoghurt is usually safe in small amounts for most dogs. Avoid flavoured, sweetened, or low-fat yoghurts — they may contain xylitol, which is toxic.

### Is yoghurt good for dogs?

Plain yoghurt provides probiotics and calcium, but complete dog food already supplies balanced nutrition. Treat yoghurt as an occasional snack, not a dietary staple.

### Can dogs eat Greek yoghurt?

Plain unsweetened Greek yoghurt is fine in moderation — it is lower in lactose than regular yoghurt. Still check the label for xylitol and artificial sweeteners.

### Can puppies eat yoghurt?

Small amounts of plain yoghurt are usually fine for puppies over weaning age. Introduce gradually and watch for diarrhoea — some dogs are lactose intolerant.
