Poor pup, will have you in my prayers for sure. If all she wants is hot dogs, so be it. I recall someone saying when they needed to help their dog walk they used one of the fabric grocery bags and cut down the two sides so that they could sling it under the dogs belly and use the handles to carry the dog's weight. Sounds like it would work well if you have a heavy enough bag. Just a thought for you.
Hugs and prayers.
