my dog food

Question
I have a 3 months old shit zuh I want to you know if  I can give him a homemade food like  white rice or chicken breast or if he is to young for homemade food?

Answer
You only get one chance at proper nutrition for a growing puppy.  Home made diets are risky enough for an adult.  While dog nutrition is complex, it is well known.  Puppy chows are carefully formulated to give a puppy everything it needs.  It takes a lot more than a couple of ingredients to meet all of a dog's needs.  For the AVMA's position on this, see http://www.avma.org/press/releases/070404_homemade_diets.asp
