I swear he just does not stop peeing(Well I also swear he drinks about 3 gallons of water a day). Its amazing, He sleeps/holds it all night, gets up in the morning goes out to pee and poop, then comes in 15 min later and pees again!!! He will be 5 months old on sep 14, This is driving me nuts, in all other aspects he is getting better just not in this one, I was so excited, he went 2 days accident free and then it began again...HELP, he is having about four pee pee accidents a day, and they are all after he just peed outside!!(He does poop outside 100% of the time)

You have to take him out after every time he plays, eats, drinks and sleeps. Even then, you will have accidents. How often are you taking him out?

After he naps,eats,and plays lol, I have been constant with it, it averages out to every 45 min, maybe I just think he should be able to hold it longer then that, he only pee's i the house and I know everyone says they don't really have full bladder control until 6 months, he knows he should not be doing it because after he does he runs and hides. Like I said he will go out, pee and then go inside and pee 10 min later.

Every 45 mins may not be enough. To really get him on the right track you may need to start taking him every 30 mins.

Do you catch him in the act or find the pee afterwards? What are you using to clean the pee spots?

I would be careful of claiming that he knows he does it. Dogs don't really have the emotional capacity that humans do and there could be a number of reasons that he appears to run and hide after he goes in the house.

I catch him in the act, I use 50% water 50% white vinegar to clean the urin after he goes. It just he can be outside, pee then comes in and in 10 min pees again so its a little frustrating, He makes it 10 hours a night without peeing or pooping(Granted he is sleeping for this time) and when he has to poop he sits by the door, is it just that he really does not have the bladder control and when he has to go he can not hold it, if that's the case I would not be as frustrated, but if he is just not catching on, thats the frustrating thing. Oh yes he will be 5 months next week.

Ok maybe he does not know, but the only time he runs is when he goes in the house, and he is not getting hit or anything, if he pees we immediately put him outside then clean it.
