Yes, take him outside to potty! Is he neutered? If not he could be "marking" his territory! I have one that is pad and outside trained. She goes on her pad when I am busy and goes outside with the rest to potty if she wants. When we are away from home, she potties outside on command. I trained her this way right from the start. Praise for good behavior....... say go potty and when she does.... praise, praise, praise!

Confining works for some, but since he has just recently be subjected to this, he probably think he is being punished and just doesn't understand what you want. I would try getting his potty scent on the pad and see how it goes.

Could he be upset when you are working and wants attention and that is why he potties in the house?

I have a male that does that when his "dad" goes outside without him. I have to watch him close!

Another thing might be a belly band to prevent him from peeing everywhere.

I am just throwing out ideas in hopes of something helping.......best of luck!
