The NBA offers a warranty for pedigree animals. This is a legal document which is signed by both the seller and the purchaser setting out the terms and conditions of the sale and the liabilities and obligations of both parties. It can be backed up by insurance. The full text can be seen on the NBA website and Gascon Society members can use these warranties at no cost as the Society is an NBA member.
It is worth thinking about, especially for bulls in the event of infertility, as it sets out exactly what can be claimed for and gives time limits for claims. Please contact the breed secretary or the NBA if you would like any more information on this.
