<p>The device has a base with a metal surround and is formed with three compartments (13, 14, 15) to receive removable troughs lined with grit or other absorbent material. A hollow profiled member has planar walls (16, 17) and a profiled wall with projecting parts (18, 19). These fit over projections (20, 21) on the base and simulate posts for attracting dogs. Chambers (22, 23, 24) are filled with a substance to attract dogs and this is distributed over the lower surface (25) through holes (26, 27, 28). Plane surface (16) enables the apparatus to be placed against a wall.</p> |
