We have an 8yr old very nearly 9 yr old Yorkie named Sadie. We have had her for a year as she was abandoned, god knows how anyone can do such a thing but they did. She has a bit of a bladder problem and can't always hold it all night. We trained her to go on paper which she learnt very quickly. Well thats what we thought. What seems to have happened is that she is using a particular spot. If we don't put it in exactly the right spot she misses. We also tried moving it and she automatically goes to the other place where the paper was. Any ideas on what we can do?
