I use the panties when I take my dogs to other people's houses or shopping or when we are in a hotel. They work really well.
I also use a pet-a-potty on an outside neclosed and covered patio which may be an option for you on bad weather days. You can use artificial or real grass in it and my dogs like it. It says you can use it indoors too so maybe a laundryroom or a garage would work.
Here is a picture of the pet-a-potty.... |
