Can A 5 Week Old Rottweiler Puppy Eat Pedigree Puppy Food?

First of all this brand of food lists corn as the first ingredient and chicken by-product meal as the second.

• Corn as a main protein source is a poor choice.  Use a brand of food that has a meat(not meat meal) as  as the first ingredient.  

• Chicken by-products meal is the dry ground, parts of the chicken carcass(after all good  meat has been removed),such as necks, feet, undeveloped eggs, and intestines and sometimes heads and feet. It is of poor quality and hard to digest.

At five weeks the puppy should still be with the mother.  Even so, it can start on moistened dog food and water. Puppy milk replacement can also be used to moisten the food.
Several brands have meat as a main ingredient -check the labels. An affordable choice is Purina One Puppy food with lamb and rice as the first two ingredients. Having said that,  there are many better choices but they are higher priced premium foods.  One should purchase a premium dog food with the best ingredients they can find and afford.
