David Grant and Yvonne Faulkner-Grant of Warwickshire, England always let their 13-year-old dog, Scruff, pick up the plastic bottles he finds while out on their daily walks. The dog carries the bottle for a while, and they kick it or throw it for him to chase. The game is over when Scruff loses interest and drops it.

Throughout 2021, David and Yvonne observed Scruff’s habit of finding even the most well-hidden bottles. They also noticed a marked increase in the amount of litter in their rural area. David says they were both taught never to drop their trash as children, so they couldn’t believe that people were littering so much. At the start of 2022, David and Yvonne decided to start picking up the bottles to bring home with them. It was the large number of litter that made them decide to train Scruff to gather other people’s trash.

Since starting this journey, Scruff has become a local celebrity in his neighborhood. David and Yvonne never let Scruff pick up anything dangerous, like glass. They also remain appalled by the amount of litter they’re seeing, and hope that people will hear Scruff’s story and either stop dropping trash or, perhaps, try picking it up themselves. Plus, Yvonne thinks Scruff took to his duties so well, other dogs could easily be trained to do what he does as well.

In the end, Scruff was able to gather up 1,334 bottles — along with three cups, a Pringles tub, and a baby feeding bottle. “If we walk the same route every day, he will find bottles on that route every single day,” said David. “We feel a bit of pride that we are picking them up, but a bit of anger that they’re even there,” Yvonne said.
