Dogs suffering from oral diseases such as stomatitis, oral ulcers, and dental caries, or digestive system diseases such as gastroenteritis and pancreatitis, will also reduce the dog's appetite. It is recommended to consult a doctor for medication.
If the puppy has just arrived in a new environment, it may not eat because of nervousness and fear. The owner needs to appease the dog's emotions and get the dog familiar with the new environment as soon as possible. If the puppy does not like or is tired of eating this kind of dog food, it may be caused by picky eating. The dog's eating habits need to be corrected and the feeding of snacks should be reduced.
