Bone Spavin

[lizijj]

Hi, one of my horses - I bought at 4 years old (HanxTB, 15:2) broke in, and shortly was diagnosed with bone spavin of the flat joint on hock (shortly realised he had this problem before I bought him...). I thought it was the end for him, but left him in the field for a year and he came sound in the field (flat joint fused). He now has a lovely life with our herd, but I sometimes worry he is bored in the same surroundings... He can be ridden but seems very twisted along spine and neck. In the field he is like Black Beauty! I want him to have the best life possible, any ideas?? He also has some vision problems, not blind but very wary - although can pick up things miles and minutes before the others!

Thanks
