start all over. Not being mean, just real. She needs ALL freedom in the house taken away. She must never be allowed free roaming until house broken. On leash at all times in the house. If she is not on a leash, she must be in a crate or an x pen. Clean up your house as much as you can with natures miracle or something similar. Then and only then can you begin to make her understand the basics of beginning housetraining again. I loathe puppy piddle pads as they teach dogs to pee in the house on absorbant surfaces, but the most important thing you need to do is have a positive attitude.. Lots of praise for peeing outside. The book "what all good dogs should know" is a great book.
I rescued a tibetan spaniel a few years ago. She was 7 years old, not spayed, had bladder infection, bladder stones, ear infection and she was used to peeing everywhere in the house and even in the bed and on the sofa of her elderly owner. Many thought she was a lost cause. In my house, dogs earn their freedom. I took away all her freedom, she was either leashed or confined. She now is very well housebroken and allowed the roam of our house. Yes old dogs can learn proper behavior. Easy to train the dogs, harder to convince the owners it can be done. I used to chuckle at a friend telling me about her scottish terrier puppy pooping in her dining room. she was complaining and I said, well... what did you do when you saw her pooping? She says... well, I wasn't there when she did it.... hmmmmm. I said. Then you werent using the leash in the house then? She laughed and said "caught me". Her dog just needed her to have some consistency. It is easy to train difficult to house break breeds to be housebroken if the owners will just keep the dog at hand during the training phase. Dogs will rarely do it in front of you. Put a clip on your beltlook and hook the leash to it. When you catch your dog in the act of going potty in front of you, interrupt the behavior, take pup outside, and praise praise praise. I typically set up a designated potty area outside for difficult dogs. I had an xpen for my bonnie with a tarp over it outside and I would watch from the door on a rainy day. As soon as I spotted her going potty I would rush out, praise and reward and let her come in. I have a rule, I am not going to get wet and walk the dog all over the place while they hold it and save it for inside the house. I say, hey... u get wet... I will let you come in when u are done. Some dogs like privacy to do business and this approach works for those. If you can at all get spencer some obedience training that would help too for respect. Dogs that are coddled too much can often become tyrants in the home. Also a good idea to rule out medical reasons first. With my tibbie, if I had concentrated on only the housetraining issue, I would have missed the bladder infection and bladder stones my girl had. It was impossible for her to be housebroken with her medical issues. She needed medication and prescription food and diligent training and now she is a happy well adjusted sweetheart of a dog. Best wishes.. never too late! You are a great owner to take the responsibility on your shoulders rather than blame the dog! I wish everybody was that honest about themselves.
