weak hooves!!! help!!

I have shod and barefoot horses and ponies with the help of two very good farriers. I think a very good farrier who is willing to explain his methods should be your first port of call. Get one who knows about barefoot methods or search the net for a local.
Secondly I agree with a suggestion above by not oiling everyday to maybe once or twice a week and soaking the feet with water for at least 10minutes a day. The hoof wall needs moisture to remain pliable and the oil may be stopping or robbing this.
Ask your farrier about bevelling or the mustang roll as you may know it, its like rounding off the foremost edge of the hoof (normally left flush when shod). This will improve function and guard against splaying or cracking. You may need to give up some normal routes if you choose barefoot until you have established a well formed and hardened hoof but it may be worth it. :)

I used to have a horse that always lost his shoes when it rained and was very weak hooves but just ask your farrier.

Ello... i'm a new user... Skye... was just about to post a question myself when I saw this one. One of our horses used to have extremely weak feet... typical thoroughbred... and it seemed like we were constantly ringing the farrier to get him to come out and reshoe him. It got recomended that we try bluestone and water... and it worked wonders! After a few weeks his shoes were holding for at least 6 weeks. I'm not sure wether it will help in your situation, I.e. Wanting to take the shoes off and harden his feet, but it seemed to help our horse hold shoes, so I guess his hooves overall would've been stronger/healthier.
If you want to try it, just buy some bluestone, put a couple of tablespoons in a spray bottle and mix it with water. If he's got shoes on, you know the mix is stong enough if the shoes turn a pink/coppery colour. Done! For the first week, apply it every second day, and after that about twice a week. Good luck!

I use bio bloom which has worked wonders on my ex racer, her feet are so much better and also her coat is really shiny. Maybe if you try laying off the oil just to harden the feet hoof oil softens the feet and maybe wait until the feet have grown a bit stronger and then continue using it :)

Also I agree with everyone else. Ask your farrier or maybe get a second opinion from another farrier if you havnt already
