Maybe get into the habit of taking your dog out once every hour while he is really young whether he needs to go or not and then increase the time between trips until he learns to tell you when he needs to go out.

I hope this helps and that it works for you. Keep us informed.

Hello,

My pom was like that too at around 6 months and from then on he got better and better at waiting until someone let him out. The only thing I could do is watchout for him whenever he goes near the door and open it as soon as I can to let him out. I think by doing that, he learned on his own to wait until someone opens the door for him to do his business outside.

Good Luck!
I know I felt like my puppy was never going to learn but he eventually did.
