The Rochdale Observer reports:
Mr Trainer was walking Scottie on fields behind Heybrook Primary School on Sunday when he noticed a small fire burning in woodland and a group attempting to start a second blaze.
When he told the group to stop, he was given a barrage of abuse – including the threat to set Scottie on fire.
Mr Trainer took pictures of tyres, pieces of wood and large pieces of fencing, all of which have been burned. He has handed these, and video footage of both incidents, to the police.
Mr Trainer also says a large amount of leaflets is regularly fly-tipped in the area, and believes if this problem continues it could increase the risk of a large fire in the area.
He said: “The arson is bad enough but to say something like that about my dog was awful.
