Verdict: In moderation
Yogurt is generally safe for dogs in moderation, but many dogs are lactose intolerant, which can lead to digestive upset. Opt for plain, unsweetened yogurt without artificial sweeteners like xylitol, which is highly toxic to dogs. Always introduce new foods slowly and observe for adverse reactions.
