Potty training..

A puppy younger than 14 weeks old doesn't have bladder control, nor do they have understanding of how to 'indicate' they need to go.

So, here is the sequencing for training a puppy to go on command

1.  Keep your puppy contained where you can see it at all times.
2.  Take it out to the same place, out the same door, EVERY TIME on its check cord and give it your 'potty' command. Stand there with your foot on the check cord and wait and wait and wait, reissuing the command 'Go Potty' until they go. 
3. THEN, make a BIG production of the fact they went, "OH GOOD DOG...what a good dog you are."  
4. Recall the puppy, "Fido, Come" after they relieve themselves, command "Touch" and have them touch their nose to the palm of your hand. SMILE as you praise them verbally and a Recall, "Fido, Come" MUST always, no matter what, be done with a smile, praise and your body language MUST convey 'welcome'. NEVER punish or reprimand or discipline a puppy/dog for ANY Recall as someday that Recall will save your dogs life.  So, get your puppy used to a 'Recall' after doing its business so you are able to physically touch your puppy and convey how pleased you are. 
5.  Watch your puppy closely in the house as when it starts playing, the puppy will get excited and eliminate. When this happens, be a 'DRAGON!' and yell a little bit with an "AHHH#!" sound as that will startle the puppy and cause their muscles to contract.  Immediately pick them up and escort them outside to their potty area and repeat # 2-4.
6.  When the puppy has made a mess, after you take it outside, then kennel it for a few minutes as you clean up and make sure you clean up product designed to eliminate the dog odor as dogs 'go' by smell and once they start eliminating in the house, you must get rid of the scent. Normal soap/water will not erase the smell.
7.  If the puppy is still having issues with going in the house, set a timer and take it out on a regular schedule.  

Make sense? If you train a puppy consistently from 7 weeks old through 14 weeks, they begin to understand and will 'indicate' they need to go by running to the door and looking at you. Man, be paying attention and get them outside to their area immediately so you can praise them.

If the puppy can go 4-5 hours in its crate and NOT mess the crate, then any issues of eliminating in the house are training issues.
