Bella is 18 weeks and does great in small places (in her room with her crate and pad--no accidents). If I am in the computer room and have it gated off with a pee pee pad for her, she will go on it. If she has more space, she will go if she is close by it--I haven't seen her make a run for the pad or anything like that.
We are still in intense training mode (LOL!), but I try to give treats and tons of praise when she does it right! Definitely a work in progress!
I'm going to keep checking the post for more tips!
