First up, invest in a boatload of duct tape. Yes, the guy in the paint department will look at you strangely. At least the guy at Home Depot did as I carted an armload of the gray stuff back to the register. If I had bought zip ties at the same time, he no doubt would have called in the FBI. The thing is, if you buy only one roll, you're asking for a lengthy abscess. If you purchase way more than you'll ever need, your horse will never abscess again.
If the abscess is still stuck somewhere in the hoof, you'll need some kind of poultice like Numotizine or Ichthammol to draw out the abscess. Once it's blown, the hole that it creates can lead directly into the hoof, so you'll need to clean and protect it until the tissue has epithelized. This bandage is for after the abscess has blown. If the abscess hasn't blown substitute the flushing and gauze pads with Numotizine.
For all bandaging jobs, I like to rewrap every other day. If you're interested in doing a pressure bandage, check out this post or this one.
And I guess a thank you goes out to Speedy G for providing this learning opportunity. I appreciate the effort, dude, but I think I've got the bandaging thing down. No more experience needed!
