Can Dogs Eat Yoghurt UK?
Published Last updated 2 min read
Quick answer
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.
Key takeaways
- 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.
- Plain yoghurt provides probiotics and calcium, but complete dog food already supplies balanced nutrition. Treat yoghurt as an occasional snack, not a dietary staple.
- 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.
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.
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.
