I feel for you! I rescued a beagle puppy that had never been out of a gage :( We spent 8 months trying everything we could think of to housebreak her. Puppy papers. Walks. Sprays. We have a Jack Russell that never has accidents and we have a doggie door to the outside open all the time!!!! She was going to have to go to another home and as a last ditch effort I sent her to boarding school for a month. She lived in their house with 5 of the biggest labs I have ever seen .They won all kinds of ribbons and awards! I was so nervous she would fall back into bad habits since the trainer said she was most difficult to train. She came back and has never had another accident for 2 years! She also got manners and learned to walk on a leash along with tricks and obedience commands. It was expensive but worht every penny to be able to keep her.
