Yes.....founder with Hoof bone rotation.
Have you had much dealings with these sanctions and rescue farms?
Yes, a few. Mostly smaller local ones. It can be very frustrating because most are kept running by volunteers, many who have very little horse experience. They often volunteer just because they love horses but do not have the knowledge or skill to do the right things for a lot of horses. And many are running on little money, and can not afford the needed veterinary and farrier care for the worst problem hooves. Yet they keep getting more horses that they can not afford.
Some rescues though do very good work, and use terrific veterinarians and farriers on a regular basis. Some just get whoever will volunteer time and often it is beginning farrirs or trimmers who lack experience.
The biggest and best one in the United states is Best Friends rescue in Utah. Their equine rescue program is great.
I know their head farrier, Jen Reid. She is SO knowledgeable and dedicated, and works with a team of very good veterinarians.
They have rehabilitated some extremely bad hoof cases. And they will get help from even bigger hoof experts when they have to.
They had Dr Ric Redden from Kentucky help them on a very bad canker case.
