Can dogs drink soya milk?

Dogs are omnivores and can drink soya milk, which is a good vegetable protein. However, as dogs are individual and have different states of gastrointestinal function, some dogs may develop gastrointestinal allergies or digestive intolerances after drinking soya milk and may experience vomiting and diarrhoea. If vomiting and diarrhoea are present, it is not recommended to feed it.
