Ask H&H: negligent fellow livery user

Q: I kept my horses, plus a mare and foal, on a yard with one other person who had an Arab gelding. They had all been turned out together, without any problems, since foal George was six months old. The Arab’s owner had a sharer, whose standard of care was far from adequate and I had told the owner this.

In February, George was castrated and the vet said that, for two weeks, he and his mother should have sole use of the field. Everyone was informed. A few days later, the Arab’s sharer turned him out with the mare and foal. I returned to the yard to find George walking on three legs. A farm labourer informed me that the Arab had run him ragged up and down the field. He had torn all the ligaments around the stifle joint.
