Horse-transporting vehicle

The trailer has a frame with an axle and a wheel. A volume (18) receives horses (26) arranged in an oblique manner with respect to a displacement axis of a vehicle. A wall (Pl) is provided under the neck of one horse and a wall (P2) is provided behind the haunch of the horse. The volume integrates the wheel and has an overall width equal to the distance separating the exterior of the wheel from that of other wheels of same axle.
