My dog is going to be 16 years old this year. She's a medium sized German Shepard/Wolf mix and in her old age she's been going to the bathroom constantly, and all over the place. Sometimes, it will happen right after we let her outside. She will literally walk into the house and not five minutes later she will have gone on the floor somewhere.
It has gotten so bad that we've essentially confined her to one room in the house(there are other reasons for that too, we recently got a new dog and she doesn't get along with it.) Now that room stinks like urine and is essentially unusable even though we clean up and scrub the carpets every time she goes.
Is there anything that can be done to fix this problem? She won't let us put diapers on her without an extreme fight, and she will rip them off just as quick as we get them on. We've also tried letting her out literally hour on the hour to no avail. Any advice?
