A litter-picking Border Collie picks up rubbish on dog walks - and neatly posts it in a bin. Trinny, aged five, belongs to Alanna Jackson, 37, a devoted environmentalist who is also keen on dog training.

Alanna, who lives in Clydebank, West Dunbartonshire, was shocked by the amount of litter in their local area. She began training Trinny when the super-bright collie was a puppy, but found the community pulled together in lockdown to clean up the environment,

Last year Trinny began her litter-picking spree, and now knows 'litter' as a command, along with 'drop'. Customer service worker Alanna keeps a close eye to ensure nothing which could be hazardous gets collected.
