A lure for schooling greyhounds is provided with an electrode to which pulses of voltage are applied, and with apparatus for emitting sounds from the lure. The sounds attract the greyhound's attention and the electrical stimulation he receives when he touches the lure cause the greyhound to attack the lure and to achieve satisfaction from it. The electrical pulse generating circuitry and sound source are separate from the lure and releasable connections are provided to enable the lure and electrode to be replaced by a fresh one if damaged, without also having to replace the circuitry and sound source.
