I'm wishing you the best of luck. It's not impossible to do. Tilly was 3 years old when we trained her. She goes outside to potty. We really didn't do anything special. We just had to stand outside till she went. It was February, cold, and she quickly caught on that the faster she goes the sooner she gets to go in. When she did go, we would get really excited and give her a treat. Rarely does she have accidents anymore.
