AllBoxerInfo recommends feeding Boxer puppies a mixture of blended white chicken, baby carrots, peas, cooked rice or pasta and milk replacement. Combine the food mixture in a food processor, and add milk replacement to make the food soupy.
Gradually reduce the amount of milk replacement added to the food mixture as the puppy grows. Commercial dog food can be used in place of homemade dog food. However, when choosing a commercial dog food, the main ingredient needs to be a specified meat. For Boxer puppies, mix commercial dog food with milk replacement to make the food easier to digest. Dog Breed Info Center recommends feeding puppies 3 to 4 times a day.
