Can dogs eat yoghurt?
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 ate more than a safe amount
If your dog has eaten a large amount of yoghurt, watch for digestive upset (gas, loose stools) over the next few hours. Sweetened or flavoured yoghurts with xylitol are the real risk — call your vet immediately if xylitol may be present.
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
A teaspoon for small dogs, a tablespoon for large dogs.
And while you're thinking about what's good for your dog, keeping on top of flea and parasite prevention is just as important as diet.
