Why it is risky

Symptoms

Loose stools, diarrhoea, gas, abdominal discomfort.

What to do

Stop feeding and monitor the stools; seek care if diarrhoea lasts more than a day.

Notes

Choose plain, unsweetened, fruit-free and xylitol-free yoghurt, a teaspoon (small dog) to a tablespoon at a time; sugar-free yoghurts are often sweetened with xylitol, which is highly toxic to dogs - always read the label.
