Dogs can eat soybeans. In fact, according to VCA Animal Hospitals, some of the proteins found in soybeans are very beneficial for a dog's health.
Soybeans are a good source of protein and they can be safely given to dogs. In fact, PetMD claims that dogs can even thrive on an entirely vegetarian diet composed of foods such as soybeans, wholegrains and other types of beans, although owners should be careful to make sure the dog gets the right balance of amino acids. VCA Animal Hospitals states that the isoflavones found in soy beans can help to treat canine urinary incontinence and other health issues that affect dogs.
