Sometimes vets aren't any more qualified. Her first vet told my mother to locker her up in a little pen and give her the lowest quality grass hay she could find in very small amounts. She actually got to be underweight!
The last vet that saw her thought she should go back out on pasture. WORST advice for this horse. It only takes about an hour of grazing for her feet to be hot the next day. For some reason he did not want her up on a dry lot.
Also, most vets want to see her shod, and we did not have a good experience with shoes. She's much more sound without. I hated what shoes did to her hooves, and they really need trimming more often than shoeing allows. I don't know that the vet would have much of an answer.
I'm not arguing about getting new radiographs though, and I'm thinking I'll have blood work done again. I'm thinking of asking about pergolide one more time since diet and exercise alone have not completely resolved her occasional episodes, although they are now both much less frequent and less severe. I really feel like we are almost there, but not sure what else I can do. We are putting on muscle, though, finally, and I'm hoping that will help her metabolism.
The trainer consulted with vet clinics about cases like this where she was previously, and seems pretty educated. She likes to keep a horse unshod, but does not like some aspects of the barefoot trimming movement. Other advice about my horses' feet has really been spot on, IMO--things I had already noticed and hadn't gotten touched up, etc. This particular suggestion just seemed odd, but she's more experienced than me. Hence this thread. I will probably not change the way I'm trimming them because I'm really not comfortable trimming the sole much.
