Just an update to you all on Sandi's spay (American Cocker Spaniel) and what I ended up doing. The foam sling type contraption didn't work. She spent a great deal of time dragging her rear end along the floor in the romper suit. I ended up using one of my grandaughter's stretch cotton dresses, arms through the sleeves, skirt gathered up and safety pinned on her back, at the base of her tail. It worked beautifully!!! She did try to keep rubbing her back under the cat scratching post, (to try and get it off, I think), but didn't chew it or try to rip it off. Surprisingly, it had a very calming effect on her, no jumping around, hardly any chasing of cats. I think I will put this outfit on her when visitors come, may save lots of training.
