JMHO again. I would defentally x ray your horses feet by a qualified equine vet. Not saying anything neg about your vet. I can't & won't tell my story of my gelding who took off his right shoe for a long time & when we x rayd his feet, well , I'll leave it at that. It won't hurt to have your horses feet x ray'd. If there's nothing wrong, great. But if there is, you want to know about it. Best to you & your horse. 

Her feet have been x-rayed, my farrier requested it.  

The cross fire shoing would be a little like squaring off the back but instead of squaring off the whole toe you just angle off the side of toe that she is  catching the front shoe with, hope that makes sense

Vet and farrier said no hind end toe modifications until soundness and mechanics have been evaluated.  

The more you drive nails into this horses thin/shelly/cracked walls the weaker they will become, I would pull shoes for now and find a good barefoot trimmer and leave shoes off untill you can find the problem that you are having with her. 

Wow, sounds cool!!! I'm just old school and just had the back toes squared off a bit when I had a problem of front shoes getting pulled by over reaching while running barrels. This what you just described is worth looking into I think. Thanks for that tip.

I'm betting you will need to find an "old" farrier to find one that knows about it.  My horse also had a trailer (outside of end of shoe was turned out instead of in).  This was to make his back foot slide away from his front foot.  He really slide in his turns and would catch his front shoes as well as over reach.  I'm thinking that the "trailers" are from the reining world but not possitive on that.  They used to joke and say that my horse had everything except the kitchen sink on his shoes.  Over time he learned how to handle himself and all of that wasn't needed but it sure was nice having the farriers with the expertise to keep him going

Barefoot is what started this mess.

I have used trailers on sound horses to correct and or enhance performance issues or even to create soundness.  The farrier I am using now schooled under some of the best old school farriers in several states and his new school blended with his old school puts a creative spin on modifying shoes.

I have never squared a toe in my lifetime and never had a farrier suggest it to correct anything including forging.

Wonder if glued shoes or "cloud" boots could be used to get her through the vet exam? It really sounds like she has a soundness issue going on to me. You said when you rockered the fronts - she got sore on the back. This probably highlighted something that was already there. Granted, soundness issues don't have alot to do with the quality of the hoof she grows.

Theres more going on with this horse then bad hooves, I agree theres a soundness issue going on, and since shes pulling front shoes while running and being sore and has a resistance in wanting to extend her right hind she's got a problem. Well good luck you, we have share tips, tricks and suggestions with you but sounds like you need to make a visti to a good lameness vet and discuss this with them since we cant see whats going on. 

We have kept the shoes on for 4 weeks, without her pulling any and bruising her sole.  Caught one Sunday just before she was about to lose it so we are on track for the farrier and vet visit Thursday, fingers crossed.  Thanks for the taping tip.  We are going to incorporate the theory of it when we apply the Equipak CS.

Just wanted to clarify, my farrier did not suggest the squaring up of the back toe it was all my ideal.. 

Yes I have gotten some great tips on this thread and plan on using them.  Equipak, taping, toe clip instead of quarter clips have all been ran by my farrier.  I also went out and got even a larger set of bell boots than I already had.  Contacted my friend about OE.  All this in response to the responses I have gotten.  I have only put the bell boots in play so I have no updates to give yet.

Vets have been on board with this situation since I recognized it wasn't the norm for her to pull shoes this often.  The purpose of the thread was to get a magic wand to keep shoes on her to get her foot sound in order to do a lameness workup as I mention on the first page.   

Forgot I am not running her yet so she is just pulling shoes turned out.

I am opposed to squaring toes based on an incident I had with a horse I bought that way.  Out of desperation I did mention it to my farrier a few months ago and almost gave him a heart attack.

My vet had a cancellation so I was able to get my horse in finally for a lameness work up, shoes were still on too.  So we are dealing with a misaligned SI joint and explains why I felt it under saddle but nothing really visible during turnout and so on. It has nothing to do with the problems I am having keeping shoes on her and explains why she went so bad when we rockered the front feet.

Now to the feet.  Crappy genetics and weather.  The vet did this cool thing where we metered the moisture in the foot, then dried it with a heat gun like we were going to apply a pour in pad, metered it again.  With moisture in the foot the foot was fluffy, showed very few cracks but the minute we dried out the moisture the cracks were very obvious and the clinches loosened.  Kind of like that face cream that puffs up your face and gives you a false sense of removing wrinkles and crinkles on your face...lol  The vet likes the idea of switching from the pads and hoof packing I was using to pour in pads.  My mare can't handle much sole pressure the reason we don't normally use pour ins but the farrier and the vet mapped out a plan to modify her shoe and exact placement of a squished in foam board they believe will work for my mare.  The equipak CS will help control the moisture in her feet as well. 

Thanks all for all the responses.  

Do you mind sharing who your vet is ?   Only asking cause reading about a few things he did reminds me of a vet I have used. 

It's possible but given the location and distance unlikely.   I will shoot you a PM on FB.
