Pom-a-poo males (2) messing in house

[Peg]

I don't know what to do. I have 2 male Pom-a-poos (4 years old). They can go days and weeks without any problems while I am at work, then suddenly, it's surprise time! I came home the other day with several areas where they pooped & one even had to have lifted his leg to pee on the side of the loveseat! I could tell the most poop came from the one, Bear, who had pooped before I left that morning so I was extremely surprised to see his trail. (He walks as he poops). Since Bear likes to eat Gorde's poop all that was left of his area were stains!
They are now confined to an exercise pen in the family room. I do not want to have to keep them in this pen. Why are they so good, then they get so bad?
Bear will potty on command, not Gorde. I have tried to be the alpha dog. Yes they do sleep on the bed & couch with me.
I don't know what to do. There is no rhymn or reason as to why they just pick a day to do this! I know Gorde always has to pee where Bear peed, is this a dominate dog thing? HELP!
