The two home cooking for dogs Facebook groups that I am a member of do not recommend feeding puppies (up to the age of 12 months) a home cooked diet. This is because puppies have specific dietary requirements that need to be met. There is a danger of rickets if they do not have the correct amount of calcium/phosphorus. If anyone is thinking of cooking for their pup I would recommend seeking advice from a qualified canine nutritionist.
Choose a good quality commercial dog food for your puppy.
