A closer look at buttermilk
Cultured, so slightly lower in lactose than plain milk, but still a milk product with added salt in most commercial cartons. The details below use the specific facts for this exposure, rather than treating it like every other food question.
1. Start with the exact exposure
For a closely related comparison, read Milk. No toxic amount. The culturing lowers the lactose a little, which is why some dogs tolerate it better than milk, though not all do.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Kefir. A small amount usually settles on its own. It is not a remedy for an upset stomach and more often makes one worse. Diarrhea past 24 hours, repeated vomiting, or a dog on a sodium-restricted diet.
3. If the details are uncertain
Follow the first 10 minutes guide. Give fresh water and keep an eye on the stool for a day.
