I hope your horse has a fast recovery. I used Animax on my geldings leg injury and it helped tremendously with the proud flesh. There is some minor thickening, but the leg isn't as deformed looking as all of the vets thought it would be. Good luck!
Get ahold of True Color Farms she owns the stud Graunteed Gold ... http://www.truecoloursfarm.com/ she is not the dealer her sister is but she can help you get some and this wound is just what it works best on
Have you tried a product called EquiAide. Astringent paste. My colt had a large delta shaped laceration on his side that we didn't see until well after. All the skin flap as pulled back to the point of not being able to suture. Kept applications going daily for 2 weeks. Skin margins pulled back together and no proud flesh!
Have you had the vet out? I am no vet, but it looks to me like there may be some proud flesh. I would probably call your vet, and at least ask their advice, though I realize that they can't diagnose over the phone...
Oh man it really doesn't look that much healed 2 weeks later eh. Can't believe he is still sound with an injury like that. I really feel for you as those are 2 really nasty injuries to have in a row like that and both from the same thing. I hope everything continues to go well for you guys, neither of you need to go threw all this.
