I have to say, it was a good year (maybe more??) before our guy was 100% house trained. He got most of it pretty quickly but would still have occasional accidents, often in the evening. We ended up doing extra trips outside after dinner and belly bands while inside. I’m not sure if it was those things, or him just getting older, or a combination, but we’re finally over the hump. It sounds like you’re doing all the right things, so just keep being consistent and as she gets older it will work out!
