Despite what I heard about OTTBs, we bought a 5 yr. old gray gelding in February of last year.....
he was severely emaciated and covered in bites and sores when we got him. His hair coat was atrocious, short, scratchy and dull....He looked sick and acted so lifeless....see pic.
this is him the first week we bought him:
This is him after 8 months of love and attention and food....
Now he is such a beautiful boy...hair coat soft and shiny, weight respectable, all his skin lesions and bites have healed, and the farrier pronounced his hooves the best hooves he's ever seen on a TB.
As for his personality, he is one of the rare horses for his breed....he is kind, sane, gentle, funny and loving. Even my 9 yr. old handicapped grandson loves to pet him and kiss his nose (with supervision, of course. We do not allow children around EITHER of our horses, even our Belgian, without supervision at all times.)
In short, he is a wonderful horse with a great personality...despite the fact he is a 5 yr. old OTTB.
