We have Maggie's kennel in our bedroom and prop the crate door open with her water dish. If your puppy is very young, its temperature will not be stable and may require extra warmth. Fill a plastic gallon milk jug with WARM water, not hot, wrap it in a towel secured with tape and place it in the rear of the kennel. You must teach him that the kennel or bed is hers and it's where you want her to sleep. Of course once she is fully box trained, you may allow her her choice of resting areas.
Sources say the first twelve weeks are the most critical for a puppy.
It is during these weeks that behavior and good habits are formed. Start your house training immediately. There are few good things to keep in mind when house training your puppy. Accept that there will be some accidents and refrain from spanking and rubbing the pup's nose in it. It only adds to its confusion.
