A puppy always tells his dog owner whether he is getting too much or too little dog food in several ways. Crying is one of the most often recognized, but least likely to be always accurate. Although hungry puppies do cry, so do cold puppies, hot puppies, puppies that were disturbed from a nap, lost puppies, sad puppies, etc. Crying is simply nature's way of giving a puppy a means of telling everybody that he is unhappy. Anything that makes a puppy unhappy will probably also make him cry, even having his tummy too full. Therefore, to say that a puppy is crying because he is hungry requires a judgment on the owner's part. And since we do not think like a puppy, we have to use the reactions of the puppy's system to determine whether or not he is getting enough to eat.

Every time you give dog food to a puppy, two things should happen. First, he should have a bowel movement and second, he should urinate. Sometimes a puppy may need a little encouragement by rubbing his anal area, but he should always perform both acts if everything is going right. The makeup and amount of his feces and urine are important clues that tell you how well you are doing when it comes to properly feeding your pet. For one thing, the puppy's stool should be formed as it is expelled, but its consistency should be soft and pasty. The color will depend to some extent on what you are feeding him. But in every case, it should not vary from a pale tan to a mahogany brown. The inside of the stool may be yellow-brown in many cases. Stools that are green, bluish-white or clear signal trouble. Even tan or brownish stools that are watery, lumpy, hard or curdled may indicate something is not right. Whenever either off-color or off-form stools occur, stop feeding all dog food immediately and skip the next feeding entirely .

Begin the following feeding with a formula that has been diluted one-half with boiled water. Continue to feed the same quantity as you did the undiluted dog food. If this fails to produce an improvement in the stool, reduce the quantity you are feeding by 25 % at each feeding. If stools continue to be off-color or off-form, consult your vet.

A puppy's urination is an indicator of his water balance. The quantity should be about the same each time the puppy urinates. It might be pale yellow to almost clear, but should never be deep yellow or orange. Also, it should always be like water and never like syrup and should smell like urine. Urine that is scanty, dark in color, or syrupy, indicates that the pup is not getting enough water. More water should be supplied, either added to the dog food formula or fed separately. If the urine seems excessive in amount, unduly clear, or thin, the water concentration of the formula should be re-checked to make sure that he is not getting too much water. If urine production stops altogether for longer than four feedings, take the puppy to a vet as soon as possible.
