Answers. 1  It is best that the puppies are already weaned and are eating hard food before giving them away though it is possible to do so earlier, it is more work for the person getting the puppy. Usually this is around 8 weeks old. Puppies should be on milk until around 6-7 weeks old when weaning should start. If they are drinking from the mother, you can start weaning by leaving puppy food out that has been moistened with some warm puppy milk supplement, warm water, or warm chicken broth to make it easier for them to eat.
