Tomorrow Dry Cow is still available OTC. I get mine from Amazon. It’s my go to treatment for thrush in the central sulcus but I don’t feel it stays well enough to treat the collateral grooves. I haven’t had success there.
I looked at the Red Horse products and because it was late on a Friday, I was looking at about 2 weeks before I’d receive it. Not ideal so I did a bit more research and found an article by AFA about using poultice to treat thrush. I have plenty of Icetight and boric acid, an active ingredient in IceTight, does treat thrush. I’d say other ingredients do as well. So experiment I did and I treated 2 horses with it. I used Tomorrow Dry Cow in the central sulcus of one horse and disinfected all hooves with chlorhexidine prior to applying the poultice. Of course, it rained that day and the next day but I still had poultice present in the collateral grooves 3 days later. I do think it’s a combination of all products but the feet were much improved. There wasn’t any thrushy gunk in the collateral grooves. I was also happy I tried the poultice because it made me realize just how much mud you can go through in just a few treatments. The mud specifically for hooves is not cheap and I think this may be a cheaper, still effective method. Not sure how great poultice would be to treat thrush in the central sulcus but for the collateral grooves and as a preventative, I think it’s very good. I’d probably stick to applying the poultice once to twice a week but so far I’m very pleased with the results. I do think the mud specifically for hooves is a little thicker but with poultice being much more cost effective, I can be more liberal with application and still make it work.
