Yes, they are notoriously hard to train. It was at least 16 months before we felt Bella was 100% potty trained to every home and situation. We took her out constantly, after eating, after playing. Used the same words, go potty every time and kept her focused by leashing her and not allowing her to run around freely in the back yard. Lots of praise and treats. It took lots of time but well worth it in the end. There were days I was ready to give up but didn't and now I am so happy. Best advice . . . stay patient, think positive, and it will happen.
