A tiny puppy may eat as little as an ounce (28 grams) per day. For the first month of a new puppy's life with their new owners, the pup should be feed the same type of food that the breeder gave to them. A fast transition to a different type can cause health issues.
Be sure to read the Pomeranian food section. This breed can have food allergies or simply dislike the taste of a certain dog food. Some experimenting may need to be done to find the high quality dog food that is best for your particular dog

Fillers - The main difference between high quality and low quality manufactured dog food is the amount of fillers. Fillers are basically empty, useless ingredients which "pump" up the actual food itself and cause your Pom to feel full...when in fact they are ingesting worthless elements which contain zero nutrients!
These pass right through your Pomeranian's body and come out via the other end. 
Behavioral Issues - The behavioral issues of a Pomeranian eating grass and/or eating feces can be directly connected to the dog's diet. As the Pom is ingesting those fillers found in manufactured food, it will make your Pom feel full, but his or her body will be craving nutrients that the fillers did not contain.
Allergies - Allergies to artificial coloring and preservatives are common allergies that affect toy breed dogs as the Pomeranian. This can cause upset stomachs, vomiting, diarrhea, and external symptoms such as dry skin and a dull coat. Many cases can be severe; but by following healthy home cooking methods you can make sure your Pom is receiving the nutrients he needs, while keeping those nasty chemicals out of his body.
Wheat - For those who already know that a Pom is allergic to wheat, you can make delicious wheat-free home cooked meals for your Pomeranian.
Teething - Why watch your Pomeranian suffer through the teething phase, when you can make tasty home made treats that will greatly help with discomfort.
Marketing Schemes - Puppy food, adult food, senior food, pregnancy food...When you home cook for your Pomeranian, you do not need to worry about the age of your dog. These recipes fit any Pomeranian of any age.
Raw Food Diets - Scientists have traced canines all the way back to 4 specific wolves - amazing! Having originated from wild animals, our fluffy little friends still have the instinct to eat raw meat. For those who wish to see if their Pom enjoys a raw food diet, you will have recipes for this as well.
Tummy Trouble Times - There will be times when your Pom is feeling down, perhaps recovering from a treatment or just having an "off day" and dealing with an upset tummy. For those times, read the recipes for "Upset Tummy Food".
Trust - Your dog trusts you to feed him. He sits nice while you prepare a meal and licks the bowl clean. But what did you just give your Pom to ingest? Did it have chemicals? Fillers? What about meat by-products (did you know that this includes road-kill & animals that die on the way to facility .
