Dogs can eat apples in moderation. Eating apples can help dogs supplement trace elements and vitamins. Organic acids and cellulose in apples can effectively promote intestinal peristalsis and have a certain effect on preventing constipation in dogs. Pay attention to the following points when feeding apples to dogs: 1. Remove the core and check that apples are toxic to dogs. Second, cut small pieces, because dogs often swallow food without chewing, and large pieces of food may cause obstruction in dogs.
