Welcome to YT!! I don't have any advice on the coat - I'm no expert on that, but we have plenty of experts that will be by.
But it sounds like you're doing an awesome job on potty training!

That sounds very similar to how I've housetrained mine. I'm assuming that she's a puppy, so do be patient. My philosophy is to make it nearly impossible for them to make a mistake - sounds like you're doing a pretty good job of that. The other thing that I do is give GREAT treats for pottying. Better than sit/stay treats during housetraining, since that's the premium "trick" I want them to learn.
