Housebreaking took me almost 4 months with Aubrey. I learned the hard way, I started taking him out about every couple hours, then I noticed that taking him outside was a waste of time, since hes peeing in the house more. Then I took him out about every 30 mins, and kept a close eye on him, and by doing that for about a month, hes fine now
! Good luck. You can also check out the training forum theres lots of good info in there.
