i dont remember her having any trouble taking a dump...did the vet tape up her back legs? doing so will keep her legs under her and keep her from running and putting pressure of the breaks/fractures. just envision a prisoner with leg shackles, that is what it reminded me of... just use the "sport tape" that is used for wrapping a athletes ankles and allow enough lenght for her to be able to walk using short strides. id say about 8 to 10 inches of play between the legs. double reverse the tape so there are no sticky areas exposed or touching the fur on her legs. and by the way, my name is Alfred - not shawn...
oh, and when you take the tape off the dogs legs will spread out and she'll have a real wide stance, but it will go away after time...
