This is the basic pattern to follow. You will just judge by his success or failure if the timing is right or not. If he is responding, broaden his times a little at a time until he is finally safe to be out for hours playing. By the time he is 4 months old he should be able to be trusted out for several hours at a time and in his crate without soiling for 8-10 hrs at a time (mostly at night, these are VERY social dogs and should not be crated unless it is necessary and for as short a time as possible). By six months, most have the run of the house. Be careful, dogs are sneaky. They learn fast that you do not like them to do their business on the floor or inside so they will sneak off into a secluded part of the house to do it….don’t let them outsmart YOU!
