My 9 year old shepherd has a fistula on her rear end. I've tried the cone of shame (she freaks out with that); I tried the inflatable doughnut, but she still can reach; I tried the diaper, but everytime she has it on she pees in it. I was wondering if anyone has any other ideas or has tried some at home solutions to keep her from doing this. I was also wondering if one of those straps that dogs in heat would work. I don't know how far up they come. Any help here? Thanks.
