Sure, I like someone who knows what they want. Have three! I had a bit of a rude shock once it was too late to back out - I was like “who the hell glued these quarters down man?!”
Still gotta seal the area. Getting to this point took me far longer than I care to admit.
Honestly, I’d try to phase out the inside sheet for her. You’re doing all the right things - taking her out regularly, and after every meal - she’s old enough that she should be able to hold it between outings (nighttime can be tougher). If you don’t have a dog-door, now would be a great time to teach her how to let you know she wants to go out. I taught my dog to ring a bell (like on a hotel or shop counter) when he wants to go out. I started by teaching him to give me his paw, then getting him to do it while the bell was in my hand, I would ring the bell every time I went out the door, would get him to do it and then just let it evolve. It’s been so helpful for him to communicate what he needs. Esp as he’s a bit of a vocal dog - helps to know when he needs out.
The best way in my experience is to get to her outside before she has a chance to go inside. It may mean waking really early or going to bed late so that she can last between trips outside. There might be some accidents while she gets used to it, but for example, if you can take her out first thing in the morning before she wakes up, and then (like you do already) reward her with lots of praise and treats when she goes outside, she’ll get the hang of it pretty quickly. The trick is to to give her so many opportunities that she won’t have an accident inside.
That’s what’s worked for me in the past n
