don't worry about it. Pups get housebroken at different rates. Kai is now 10 months old and has only been housebroken for about a month and a half. I took us about 5 months to housebreak him. If you want to speed up the process, make praises more enjoyable (spend a few minutes on praises...maybe even give a bit of food everytime he does it correctly) and more stern NO's. Update us when you can..good luck!
