Yes, most dogs can eat a little plain, unsweetened natural yoghurt as an occasional treat. The key words are plain, unsweetened and small. What you must never share is anything sweetened with xylitol, an artificial sweetener that is extremely dangerous to dogs even in tiny amounts. And because a lot of dogs are sensitive to dairy, yoghurt suits some far better than others.
Owners ask me about yoghurt a lot at the salon here in York, often because they've heard it's "good for the gut." There's a grain of truth to that, but there are real caveats. Here's how I'd think it through.
Can dogs have yoghurt safely?
For many dogs, yes, in moderation. A small spoonful of plain natural yoghurt gives:
- Protein and calcium, in modest amounts.
- Live cultures (probiotics), which some owners like for gut support.
- A tasty, lickable texture that's handy for hiding tablets or filling a lick mat.
But yoghurt is a treat, not a supplement your dog needs. A complete, balanced diet already covers calcium and protein, and if you specifically want gut support, a vet-recommended dog probiotic is a more reliable route than a tub from the fridge.
The dealbreaker: xylitol
This is the one to burn into memory. Never give your dog any yoghurt or dairy product sweetened with xylitol (sometimes labelled birch sugar). Xylitol triggers a dangerous drop in blood sugar in dogs and can cause liver damage, and it acts fast. Always read the ingredients on flavoured or "low sugar" or "diet" yoghurts, because that's exactly where these sweeteners turn up.
> Vet note: If you think your dog has eaten anything containing xylitol, treat it as an emergency and ring your vet straight away, or the Animal PoisonLine on 01202 509000 (a paid UK service). Don't wait for symptoms to appear.
Lactose: why yoghurt suits some dogs and not others
Here's the honest bit. Many dogs are naturally low on lactase, the enzyme that digests the milk sugar lactose, so dairy can give them wind, loose stools or an upset tummy. Yoghurt is usually easier on them than milk, because the live cultures break down some of the lactose, but "easier" is not the same as "fine for every dog."
If your dog has never had yoghurt, offer a tiny amount first and see how they get on over the next day before you offer any more.
How to serve yoghurt safely
Keep it plain and keep it small:
- Plain, natural, unsweetened yoghurt only. No fruit-flavoured, no sugar, no sweeteners, and never xylitol.
- Full-fat is fine in tiny amounts, but avoid rich, creamy or sugary tubs, especially for dogs prone to weight gain or upset tummies.
- Start with a teaspoon for a small dog, a tablespoon for a larger one, and not every day.
- Use it as a vehicle: a thin smear on a lick mat, a dab to hide a tablet, or a little stirred through food for a fussy eater.
- Skip it for dogs with a known dairy sensitivity, pancreatitis history or those on a special diet, unless your vet says otherwise.
What to avoid completely
- Anything with xylitol or "birch sugar": extremely dangerous to dogs.
- Flavoured, fruit or sweetened yoghurts: too much sugar, and possible hidden sweeteners.
- Chocolate or coffee-flavoured yoghurts: both contain substances toxic to dogs.
- Yoghurts with grapes, raisins or sultanas mixed in: these fruits are toxic to dogs.
Keep yoghurt and all treats to no more than 10% of your dog's daily calories, with the rest coming from proper, balanced food.
Frequently asked questions
Is Greek yoghurt safe for dogs?
Plain, unsweetened Greek yoghurt in a small amount is generally fine, and it's often lower in lactose. Just check there are no sweeteners, and introduce it slowly.
How much yoghurt can a dog have?
A teaspoon for a small dog, up to a tablespoon for a larger one, now and then, not daily. Watch for any loose stools, which suggest dairy doesn't agree with them.
Can yoghurt help a dog's upset stomach?
Some owners find a little plain yoghurt settling because of the live cultures, but for a genuine or ongoing tummy upset, a vet-recommended probiotic and a chat with your vet is the better route.
Which yoghurt should I never give my dog?
Anything sweetened with xylitol (birch sugar), any sugary or fruit-flavoured yoghurt, and anything containing chocolate, coffee, grapes or raisins.
