Amanda, I am so very sorry that Ranger has sores on his little footsies. I have found the absolute BEST of the BEST wound medicine is Herbal Wound Spray made with 100% pure Emu Oil. The company that makes it is Laid In Montana, here's a link:
Buy emu oil online - All natural products from Montana . We used the spray on a young stallion who got silly and cut his back leg on a piece of wire right at the hock - there wasn't much to stitch, but Doc did the best he could and left the Herbal Wound Spray for us to use twice daily. The results were incredible..... the healing was slow, which was a good thing, from the inside out, but once it was healed the hair even came back chesnut - with no white. He does have a bit of scar tissue because we got lazy once the wound closed up - we should have continued the treatments for another 6 weeks or so, but it was winter and cold.....
I would strongly recommend the Herbal Wound Spray - I use it on me and on both of my surgery incisions and they have almost disappeared.
