Leah is adorable!! And Yoyo is a cutie pie too! I had trouble potty training my girl too. She would be eating from her food bowl & then all of a sudden...stop, walk away a few steps, pee on the kitchen floor & then go right back to eating.
It would drive me crazy!! When she finally learned to use her pad, I jumped up & down, clapped & screamed so loud that I scared her to death. Leah's still a baby & she might still be having a hard time controlling her body. It sounds to me like you'll be patient with her.
Crate training really does help. Since they're confined in a small space, it's easier for them to learn to control their bladder. I feel bad for them when they're inside too. But most of them get over it quickly. And they learn to use their crate as a little den to when they need to get away. Mine are older, but they still use their crates. I just took the doors off. If she's being difficult, you could even try setting up a little pen in the laundry room.
Btw, that "schanuzer injection" sounds bizarre. I would be afraid to ask her what in the world that even means! Lol
Good luck with little Leah!!
