Dogs can eat apples, but they cannot eat apple cores; dogs eating apples can supplement nutrition, promote gastrointestinal motility, help digestion, remove oral odor, prevent high blood pressure, reduce allergies, and are antioxidants. Feed an appropriate amount each time, do not feed too much at one time, and it is best to cut the apple into small pieces to prevent the dog from swallowing it directly and getting stuck in the esophagus. In addition to apples, dogs can also eat pears, bananas and other fruits, but the cores cannot be eaten.
