Can dogs eat yoghurt?

Caution — plain only, small amounts

Plain, unsweetened yoghurt is usually fine in small amounts. Avoid anything flavoured, sweetened, or containing xylitol.

The full picture

Plain, unsweetened natural or Greek yoghurt can be a healthy occasional treat for dogs that tolerate dairy. The live cultures (probiotics) may support gut health, and it's a decent source of calcium and protein. The rules are strict: no added sugar, no artificial sweeteners (especially xylitol, which is now in some low-sugar yoghurts), no flavourings, no fruit pieces (especially if they contain grapes or raisins). Greek yoghurt is lower in lactose than regular, which is a plus for lactose-sensitive dogs.

If your dog has eaten yoghurt

Plain is safe. Xylitol-containing yoghurt requires emergency vet attention.

Risks to watch for

  • Lactose intolerance
  • Xylitol in 'low sugar' brands
  • Added sugar in flavoured yoghurts

Potential benefits

  • Probiotics for gut health
  • Calcium and protein

Safe portion size
