First thing in the morning be sure to take the dog outside for a pee or poop .
If the dog has soiled the bed by the time you get up, you'll know the dog does not yet have the bladder capacity to hold it all night so try and make sure there is always a way for the dog to get outside without your help, for example, a doggie door.
Don't expect that the dog will alert you when it wants to go outside.
All indoor activities should be preceded by taking the dog out for a pee or poop, your carpet will appreciate it!
If a dog is almost ready to pee or poop, but hasn't gotten around to doing it quite yet... any physical activity will usually trigger the urge to do it.
So, if a dog wakes up from a nap and you immediately start playing with it on your carpet... you're just asking for trouble! Potty break first, play time second.

Whenever your puppy cries or whines, assume it has to go to toilet, the dog may be signalling  it's frustration that it knows not to pee in the house, yet can see that all the doors are closed.
Remember, always assume your puppy needs to go to the toilet  immediately after waking up from a nap.

Stop water intake a few hours before bed time. This will help the puppy sleep through the night without waking you up to go outside.
Praise the dog when it poops or pees in the right spot, Gently scold when it does it in the wrong spot. As with any training, do not ever hit the dog.
