Oh yea, have had two rather nasty wounds on horses this summer, one to my daughter barrel horse, Left Eye, and one to my granddaughters barrel horse Ginger. You can see photos I posted today of Left Eye healing and Ginger just starting out.
I have used lots of products on both horses, but to be honest, this time exactly a week ago(Ginger was hurt almost two weeks ago) I decided to try Underwood and WOW have I been impressed with the results in just a weeks time. Already there is granulation filling up the nasty hole and the edges are pink and showing signs of granulation. You can buy it online or alot of stores seem to carry it(not where I live of course, I had to drive 120 miles one way to find it) and start using it. The directions say to spray it on at least two times a day and then powder lightly with baking powder. You just keep putting it on like that, over and over. Its hard not to clean it up every day, but according to the people I have talked to who have used it, the hardest part is not cleaning it up daily.
I admit I did clean Gingers wound today, I needed to pull the rest of the stitches that did not hold when she was sutured for the third time and were causing trouble. So, I hosed it off, then retreated it with Underwood and paking powder and left it alone. I was amazed how well it is starting to heal so quickly.
I used Shriners on my husbands horse last year for a nasty hindquarter wound. It did not even begin to heal this fast, it took months before it started to granulate, so I am sold on Underwood.
You will be told by some folks on this forum not to use it, and that is your choice. I was a bit skeptical at first, but am totally impressed by this product.
Its not real expensive, about $24. for a bottle and it goes along way because you spray it on. Of course, baking powder is really cheap these days also.
And I have not had ONE fly on this wound since I started treating it last Saturday.
Good luck, pm me if you want any more help with it.
