Welcome!
9 weeks is young, but do start training now.
Princess is now 2 years old, and I think we just about got it down.
When I first got her at 9 weeks she would go where ever she wanted.
It took about three weeks for me to find the right spot for her pads.
We put a doggie door in, and she would go out to bark, but not to potty.
So for a year we had pads down in her spot, and it worked. Then one day she went out on her own, and I'll be, she goes all the time now. She did have a few
accidents, my husband said put the pads back down, but she didn't use them.
I guess she was telling us she's a big girl now. Be patient with him, it takes time,
They are so worth it! Good Luck, and Again Welcome!
