My Phoebe is 15month old and she is a 100% potty train since she was a pup, so don't blame the breed ok, some dogs are hard to train than other and there have to be consistancy and patient too. This is what it work for me I use a playpen with her toys, food, water etc, her pads when she was out of the playpen I keep my eagle eye on her if she had a accident with a firm NO and take to her pads, or outside,REMEMBER if you correct her after she had done it she will not get it, she will not know why you are so upset about it, have to correct her when she is doing it, if she goes in the pad I praise her (make a big deal) at night I crate, her crate was next to my side of the bed and I will take her out in the night when she need it, but I made sure she had potty before I put her in her crate. She sleep now with us, and have the house for herself because she earn it
