Pups that are just one month old can be fed soft and glutinous foods such as goat milk powder, milk cake, puppy food soaked in warm water, rice cereal, etc. Because puppies that are about 30 days old do not have the ability to chew and their gastrointestinal functions are not yet complete. If the mother dog’s milk is insufficient, the breeder can add the above food as a supplement. After the dog is 60 days old, it can be changed to puppy food. You can eat or drink as you wish afterward.
