Hi, just was wondering if the vet was any help? I got a female one year old Yorkie and having trouble housebreaking her. We have a doggie door and she knows how to go out, but doesn't always do her business outside. It has been three weeks since I got her, was wondering if maybe she has a urinary infection. Of course, that doesn't explain the "number two" problem. She is so cute and get along with the family. Help!!
