The full picture
Plain, unsweetened natural or Greek yogurt 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 yogurts), no flavourings, no fruit pieces (especially if they contain grapes or raisins). Greek yogurt is lower in lactose than regular, which is a plus for lactose-sensitive dogs.
If your dog ate more than a safe amount
For a small accidental taste, watch for vomiting, diarrhoea, or signs of discomfort over the next few hours. For a large amount or if your dog is small or has existing health conditions, call your vet. When in doubt, call the ASPCA Animal Poison Control Center on (888) 426-4435.
Risks to watch for
- Lactose intolerance
- Xylitol in 'low sugar' brands
- Added sugar in flavoured yogurts
Potential benefits
- Probiotics for gut health
- Calcium and protein
Safe portion size
A teaspoon for small dogs, a tablespoon for large dogs.
Does size or breed matter?
Lactose sensitivity varies between individual dogs rather than by breed or size specifically — many adult dogs have reduced lactase production and can react to any dairy product, yogurt included, regardless of how small the serving is. Start with a very small amount to check tolerance before treating it as a regular addition, and keep portions modest in small and toy breeds given their lower overall calorie allowance.
