My Louie is 8 months old and some days he's good with the training and others just horrible.  I feel like my days are filled with cleaning pee mess, but everyone tells me it does get better.  They are like kids when you first potty train them-they'll have their accidents, but we all eventually get it.  Stay patient and when you have rough days, put him in a designated area for a little while (Louie has the kitchen gated off) and go relax.  When you come back to him and see that cute little face staring at you, you'll be ready for another day!!
