Serving advice
Treat Plain yogurt as a snack rather than part of the daily ration — the usual ceiling is about 10% of daily calories. Start with one small piece of Plain yogurt and watch stools and appetite over the next 24 hours.
Plain, unsweetened yogurt with live cultures is safe in small amounts. Avoid anything with xylitol or artificial sweeteners.
Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.
There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter
Even a gram or two of xylitol can trigger a sharp drop in a dog's blood sugar, and larger exposures go on to damage the liver.
Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
