They are not stupid Sabrina, they are making money and they don't give a toss how they do it.
an Arab stud near me has all her foals in tendon boots from about 3 months old as the foals are mostly deformed due to her not having grazing of enough length to enable the young ones to nibble grass, so the front legs become bent. The state of the mares is bad enough, the stallions never see daylight. Arab Welfare Society is a joke. RSPCA another bloody joke.
