Why are they weeing in the house?
Because they have no other option. Simple as that. They are babies and they need to toilet frequently, if no one is there to let them out, then they have no choice but to do it in the house.
This is going to take even longer because you have two pups pretty much the same age (as well as the risk of many other problems cropping up due to same sex same age puppies).
The only good solution to this other tahn rehoming them, is to employ someone to come to your house at LEAST twice a day and help with the toilet training/general training.
This wont come cheap, but realistically, your chances of housetraining these pups effectively any other way are pretty much nil unless you are happy to wait until they are MUCH older and capable of hanging on (which wont happen because they have no one there to teach them to hang on).
Sorry if thats not what you wanted to hear, but on face value, getting two puppies of the same age whilst you are working full time is not the most sensible of things (and thats putting it mildly)... how did you come to HAVE two pups?
