An animal welfare organisation is encouraging Manx youngsters to become more conscientious following the "barbaric" killing of a Labrador.
The killing of the Labrador has shocked islanders
The chocolate-coloured dog was found dead on 5 February next the Sulby reservoir on the Isle of Man.
Its muzzle had been bound and its legs tied with duct tape.
People for the Ethical Treatment of Animals (PETA) is sending "emergency humane education materials" to schools across the island.
Kate Schnell, charity administrator for PETA, said: "Putting a stop to violent tendencies as soon as they become apparent should be a priority and the responsibility of all of society."
Police are continuing to follow up scores of leads following an appeal to track down those responsible for the death of the Labrador.
They spent the weekend talking to dog walkers at the reservoir in a bid to get fresh information and are now in the process of pursuing at least 60 lines of inquiry.
A reward of £2,500 has been offered by a local business for the prosecution and conviction of those responsible for the dog's death.
