Ina G. is on the money in everything she said. It isn't fair to any of you what has happened so far. I never was a fan of dogs in the house either, until we got ours. I had a roommate that had one, and I HATED it. It was gross and nasty and just ugh! But she never trained the dog. The dog was basically a big spoiled brat that had no rules.
Before we decided to get our dog we had lots of discussions. There were really 2 choices for us (and for most people, only they don't think them thru up front). Either a) keep the dog outside at all times forever. In which case the dog is dirty, stinky, starved for attention, and basically amounts to nothing more than one more chore; or b) keep the dog inside at all times (except for the bathroom) so that it is PART of the FAMILY, well trained, clean and well-mannered, and easy access to play with.
There really is no middle ground. If you put them outside "part of the time" the 'dirty' factor is RIGHT THERE and that leads to choice creep into option "a" (becoming a chore to deal with). Eventually, you will end up with choice "a".
So it is "A" or "B". The question is, which is it going to be. We went with B. Inside all the time (except for using the bathroom, and being outside WITH US playing or just hanging while we play or do yard work or whatever). It is fine. She can go long periods of time without a bath (yay--b/c that is kind of a pain and it can cause dry skin issues for her), she is well mannered, not starved for attention, knows her place in our pack, and a better "alert" system than anything I've ever encountered. We LOVE her. "I" love her. I don't mind (too much) the shed hair on the carpet--it vacuums up. She isn't allowed on the furniture, so that isn't an issue. She doesn't HAVE accidents in the house. Period. She did when she was very ill, but my kids do that.... She doesn't even throw up in the house---she goes to the door and keeps it down until she can get outside. (sorry if TMI).
You need to find her a better home or you need to step up and shoulder the responsibility your FAMILY signed up for. That includes your husband. YOU will likely be the one that NEEDS to do the training class with the dog. You are the one home with her the most. But your husband needs to pick up slack to allow you the time to do it. (including practicing it at home). And he needs to listen when you tell him the 'new way' to deal with the dog. The words, the tone, the hand motions, what they mean, how the dog is expected to respond... everything.
Read some training books to get an idea... and he needs to read them to. Yeah... it is something you and he would rather not do (obviously, or it would already have happened), but if you want your situation to change for the better, it has to be done.
And you might just surprise yourself how much you actually learn to like your dog, after you spend some time getting to know it. ;)
