How old is the horse? Is it fore or hind limb lameness? Any reasons given? My 6 year old was 1/10th lame a week ago and vet thought it worth investigating problem if she stayed that way after a few days rest, given that she was only young and should really be 100% sound. Said a lot of horses show this level of lameness though and wouldn't bother too much if my horse had been older.
I am no expert but I guess most 15 yr olds might be 2/10ths lame! Was it 2/10ths lame before flexion test or after or both? I guess you need to weigh up the price, what you want to do with it, how desperate you are to buy that particular horse and whether or not you are prepared to take the risk that the lameness could be caused by something like navicular or arthiritis etc and get worse. Did your vet have any views or give you any advice?
Yes it is a big issue if you wish to have a sound horse!!!
You'd be buying problems.
If a horse fails a flexion at that age that is slightly different but for a horse to be 2/10ths lame is significant. My TB is only 1/10th lame most of the time but has significant ligament damage. Horses cause enough heart ache, no need to buy one with problems.
My 16 year old mare is around 2/10ths lame at the moment, increases to about 4/1ths if shes a tit. She is on box rest (currently on week 8) having been scanned, treated and booked to be rescanned.
I would NOT buy a horse 2/10ths lame. Its bloody expensive to find and fix any problems. Buy a sound one.
