When the Bichon Frize is almost 3 months old, it can be completely fed dry dog ​​food, because the 3-month-old Bichon Frize puppy begins to enter the tooth growth period, and its chewing and digestive functions have been significantly improved. Dog food can effectively help tooth development and also clean the mouth. However, it is best to make a transition from soaked dog food to dry dog ​​food. It should be gradual and not too sudden. Otherwise, the dog's stomach and intestines may not be able to adapt for a while, resulting in diarrhea or poor appetite.
