My yorkie is almost 2 yrs old and still has accidents. I have trained her to go outside and thought it would be easier to get a doggie door. Well, that worked UNTIL night time. She thinks that since nobody is watching her that she can get away with pooping in the house. I have tried bringing her to the location and getting on to her and putting her out the doggie door. I don't know what else to do. I feel her peeing is going great outside (at least as far as I know)
The doggie door is so convenant and I recommend everyone getting one. Just find a way for her to go out at night too!

If anyone has any suggestions on that let me know
