Housetraining is a long and on going process during which you will need to take her out to do her job and during which she must never have the opportunity to be unwatched to the extent that she is able to keep going on floors and bedding. This simply should not be happening if you are using the advice given here by many who have posted back to you in previous threads and also the kalstone book. A key element of all advice and the book has been: she MUST NOT be allowed to roam around without being under constant watch and in constant reach and needs to be either on your lap, tethered to you, carried, or in her crate when she is not being taken out to do her job.
If you do a mix of taking her out and then, not watching her so that she also has the regular option of going on bedding and floor, then she is being trained that she has two valid options. She shouldn't have that second option, ever.
Dogs also learn to go where wanted on a very variable scale of learning. Some dogs learn quickly as puppies. For most, they will not become somewhat reliable until 6 months of age and will have occasional accidents almost certainly til a year old or so.
Some dogs will never let you know they wish to go out unless you specifically train them to do this. My three never indicate they want to go out but they go out with me on a very regular basis. If you want to train her to signal you this is an added level of training you should undertake now.
A dog can only learn what you teach it. Generally dogs that get a lot of dedicated time for housetraining and that are always set up for success (eg they get rewards for going where you want and never have the opportunity to make mistakes because the *owner* makes sure they can;t happen) learn the fastest and are much more successful than those who don't get a clear message and remain confused about what the owenr's want.
It sounds right now like Abbey has too much unsupervised freedom for a puppy (otherwise she would not be able to have these accidents) and that is where you will need to make the corrections to her overall training environment if you want success. You are already on your way to getting there because she knows to go when you ask. For many puppies, it is many months before they take the option of choosing to go outside themselves.
Ps Gillian can you try and reduce your avatar down a bit? It is about a third oversize. The maximum size I have set is the width of my own avatar and larger ones make threads harder to read for people with small computer screens. There are directions on sizes and resizing in the Getting Started section.
