My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
I see that you are dealing with a lot of issues. Personally I believe in strict crate training for dogs which means they stay in the crate all the time except to go out to eliminate and if they do eliminate outside they then get a reward of some free time outside of the crate. If they don't eliminate, back in the crate for about an hour and try again. This is the most effective way of house training.
Now that she is more used to being in your home, house training may go easier. Now it is important that you clean any place she has eliminated with a good enzymatic pet odor remove. If carpet, you have to let it soak into the padding to remove all the odor. INporous floors it also needs to sit for a little while. If you don't use an enzymatic cleanser, some odor remains and the dog will be drawn back to that spot to eliminate again. So eliminating odors is very important. If you want you can also try leashing her to you the whole time she is outside of the crate so you can stop her eliminating inside and take her out at the first sign of her needing to eliminate.
One suggestion would be to start feeding and watering her on a schedule. Keep a log of when you feed her and give her water. also keep a log of when she defecates or urinates. Soon you will see a pattern develop as to how long after eating or drinking he eliminates. This will allow you to either be sure she is outside when she needs to eliminate or move her meal time so the time she would need to eliminate is more convenient for you.
Put a bell or other noise maker on the door low enough for the dog to reach. Each time you take the dog out, ring the bell. The dog will associate ringing the bell with going out and one day ring the bell to signal to you that she needs to go out. Always go out with her. If she urinates outside, the minute she starts, reward her with a hot dog sliver as a reward. If she manages to defecate outside, reward immediately as well. Soon she will try to go just to get the reward. Another reason to go out with your dog each time.
Some dogs like being outside and if an owner brings them inside after they eliminate, they will try and "hold it" so they can have more time outside. A nice daily walk or two at the same times each day will often have the desired effect of the dog eliminating on the walks rather than inside especially if the odor is removed. Making after elimination a play time can also be conductive to house training.
Now I notice you stated she has noise issues. This is really a common problem. Many dogs have reactions to different noises. This is really a problem around the 4th of July and fireworks. For things like thunderstorms, some people tape the noise and play it back at lower volumes while playing with the dog and providing positive reinforcement for the dog's lack of anxiety while the noise is played at low volumes. Positive reinforcement would include calm praise and hot dog slices or other tasty treat (not regular treats. You then gradually increase the volume slowly until your dog is desensitized to the noise. Xanax is often used for noise phobias so I'm glad it has helped.
DAP collars might help a bit as well. They produce pheromones that mimic the ones produced by a nursing mom to calm her pups. It has proven to be helpful with noise phobias and separation anxiety as well but was used in conjunction with desensitization so it is unknown if the collar or the training was the major factor in resolving the problem.
