Can dogs eat apples and why?

Dogs can eat apples. Apples are rich in dietary fiber, vitamins and trace elements. Giving your dog some apples can promote gastrointestinal motility, improve constipation, maintain blood pressure, eliminate oral odor, and delay aging. So you can give your dog apples.
Tip:
Be sure to remove the core when giving apples to dogs, because the core contains cyanide, which is harmful to dogs. If the content reaches a certain level after eating, poisoning may occur, which may even cause life-threatening consequences.
