Apples are rich in vitamins, which can effectively promote gastrointestinal digestion of dogs. However, do not feed too much to dogs. Remove the core and apple seeds and cut them into small pieces before feeding them to dogs to prevent them from getting stuck. If a dog has a sore throat, it is usually best to eat dog food as its main food. There are also some fruits that are forbidden to dogs, such as grapes, kiwis, sugar cane, etc. Eating them will cause the dog to suffocate and die.
