My senior GSD Pasta is getting to the point where she's having more frequent accidents in the house. She just can't hold it like she used to. Leaving her in my back yard is out of the question as she gets very stressed out being outside by herself. I've come to the realization that I need to do something different for her and I think installing some ramps and doggie door to my backyard/back porch will help out a lot for when I'm not home. She's used a doggie door years ago but she was 7-8 then and very agile. I'm not sure what kind of door is best or what size. I'm looking at the Hale Giant size door as it has light magnets and is large, 15.5" wide and 27.5" tall. I'm thinking it needs to be mounted as low as possible so she doesn't trip on it. If anyone has suggestions on different brands, sizes, or anything else I'd really appreciate it.
