There is an essential point to be considered in the dog potty training. It is important that every dog owner should try to limit the liquids and foods given to the dog in the evening time. This should be taken care of as any extra amount of food or liquid could result in a mess in the night. Always remember that it takes almost ten hours for the dry food to get through the intestine of a mature dog. So try to feed your dog early in the morning and at proper time in the evening. But these guidelines are only for the initial dog potty training. Once the dog gets trained it can hold for a long time before relieving itself.
