How do German Shepherd catch its food?

Both the amount of food and when the dog is fed are important.
Food requirement may vary depending on the size of the pup, environment, exercise and stress factors.
The Best diet for a puppy in the house breaking process is one level tablespoon canned food combined with one cup moistened (with water) quality dry food. (prepare enough food to feed the pup) The proper amount of food is just as important as the proper kind. If you feed the pup and excessive amount, he will need to relieve himself more often. If you feed him too little , he will start to chew the house down.

Leave food down for 15 minutes. Do not leave food or water down during other times as long as the dog is being housebroken.
