Why Soy Milk needs caution
Soy protein is digestible for dogs and appears in commercial diets, and soy milk has no lactose. Small amounts of plain unsweetened soy milk are generally uneventful. Sweetened and flavored versions add sugar or chocolate, sugar-free versions warrant a xylitol check, and dogs with a soy allergy (uncommon but real) can react with itchy skin or GI upset.
