Cage training work wonders if its done correctly. It may be necessary for her to be in her cage until she get fully potty trained. Plus having a set routine for feeding and potty time will also help tremendously. Praising and treats help also. Be sure that you never use her cage for punishment, that will send a bad message that the cage is a bad place to be. When she does go potty outside, praising her for a job well done will work and giving her a treat (cheerio cereal) will help her get the hang of it too. You must be willing to spend long periods of time out doors with her until she gets it. Which wont be easy with cooler weather and winter on its way. (you may want to put a sweater on her). You can find more ways to train your pup on my web site. Hopefully you can find something that helps.

One things that worked for me was to take some poo outside and put it in the yard where you want her to go potty. Sounds kind of goose, yes I know, but it works simply because dogs are creatures of habit and they use their sense of smell to figure out pretty much everything in life. When she smells her poo she will be more willing to go #2 outdoors and reuse that same area time and time again.
