Update - Pictures
I have now been using No Thrush for 11 days and have attached some photos for comparrison. The first is the first day, before any treatment. I have been applying No Thrush at minimum once daily since then, and twice daily if its wet. The weather was useless the first week, rain and mud, but we've had sunny days since then which is a godsend!
The third photo being today. I can definitely notice a difference, the new frog is coming through and shedding the old infected one, and the hooves are looking much better in general. The sulci although still split is starting to spread. All though we still aren't there yet, its nice to see some improvement! Candy is also much more comfortable and happily not lame.
I would definitely recommend No Thrush to anyone who's horses hooves have a slit sulci and definitely if your horse is suffering thrush. You can apply it 1-2 times a week once infection has cleared up to prevent bacteria and other ickies building up and it keeps the thrush at bay while encouraging healthy growth.
