Okay, it's been years since I've had to deal with this (over 15) so I do count myself lucky, but it's been a pretty dry spring/early summer and Dora's hooves are just awful. There are a ton of little hairline cracks going vertically up her hooves and they're just very dry in general. When I had this problem in the past with another horse, I just gave him Biotin and kept Hoofmaker slathered on and it seemed to work just fine. The cracks didn't get worse, they eventually grew out, and his hooves seemed healthy overall. I've started doing this with Dora, because like I said, it worked before.
Well, since going into the feed store and getting unasked for advice from sales people I'm questioning myself. They're telling me to paint her feet with this pine tar oil (that may be the wrong wording) at least once a week as well as the Hoofmaker to keep moisture in. I have always heard that you only use that if the horse if in damp circumstances so that the hoof doesn't get too much moisture and prevents rot. Besides, if I use that but continue to use the Hoofmaker, wouldn't it prevent the Hoofmaker from moisturizing the hoof?
Anyhow, I'm just looking for others thoughts on this. Or if you have a completely new suggestion as a fix I'm open to it, too.
