How many meals should a dog eat a day?

Dogs under 5 months old need to eat 3-4 meals a day, because puppies’ gastrointestinal tracts are relatively fragile, and small meals with frequent meals are easy for puppies to digest. Dogs over 5 months old only need to eat two meals a day. The owner's planned feeding time can be decided based on his own work and rest time and the time he takes to walk the dog. Regular and quantitative feeding is very helpful to the dog's health.
