Instructions
Fill the puppy's food bowl with 75 percent of its normal puppy food and 25 percent of the new puppy food. Give the puppy plenty of time to investigate the new food. Be patient.
Continue feeding the puppy using that ratio for two or three days, then begin adding 50 percent of the normal puppy food and 50 percent of the new food to the food bowl.
Mix 25 percent of the normal puppy food and 75 percent of the new puppy food together in the food bowl after seven days. The puppy should be eating the new food without hesitation by now.
Fill the food bowl entirely with the new puppy food after 10 days. The puppy should be completely comfortable with the new food by this time.
How to Switch Puppy Food Within the First Months
Changing your puppy's food within the first few months is a delicate process that needs to be done gradually. Dogs have bacteria in their intestines that helps digest the food that they eat. When the food is changed swiftly instead of gradually, the bacteria amount will be reduced. The puppy will suffer from digestive issues, such as diarrhea and upset stomach.
