how do you wrap a dane's tail successfully??

Hi fellow BPO'ers. Things have been fabulous with Miss Maggie, but recently she's injured her tail from the happy wag and its starting to bleed daily now. I am not familiar with how to wrap the end of a danes' tail..any help? I have tried, but my not-so-fabulous gauze wad ends up across the room as soon as I'm done What do you use prior to wrapping as disinfectant? I have neosporin and hydrogen peroxide handy..but that's about it.

Thanks in advance experts!
