We just got him in september and his shoes were too small and crooked. I don't know how long they were like that. I had his feet trimmed and new shoes put on the first week in october.
As I've said many times, I'm all for people making their own decisions, but it's important to make *educated* decisions, rather than just following some 'experts' advice. In that regard I can only give my own opinions.
If a horse is kept shod, especially if there are problems, I don't think it's healthy for them to go much past 6 weeks max without resetting, even if there's little actual length to come off. But if a horse has hoof problems I seriously think they're generally far better unshod, at least until health can be restored.
The gro 'n win has abiotin so I'm hoping his feet will grow a little more quickly. Also, he's shod in front to help his heel have support. When the ground is softer we are going to hot shoe him with a custom shjoeshoe to help pull his heel out so that it goes straight down instead of growing in
Gro n win sounds like it has a good balance of nutrients in it. Biotin is just one of many important nutrients for hoof health & one that is actually rarely lacking in a horse's diet tho. They should get enough in their diet if they get adequate green forage - legume grass/hay, for eg, of which it sounds like that product is primarily designed to be fed with. I would personally choose a ration balancer/supp that didn't include grain, particularly corn in it though.
I don't believe conventional shoes actually 'support' anything, let alone 'underslung'(I'm guessing that's what you mean) heels. I think good trimming combined with support for *the base* of the feet - frog/sole is what is needed. His heels don't need 'pulling' back, but need to be relieved of pressure so they are *allowed* to grow straight.
