From Guinness World Records 2011: Most bottles recycled by a dog

A Labrador called Tubby, owned by Sandra Gilmore of Pontnewydd, Torfaen, UK, has helped recycle an estimated 26,000 plastic bottles over the past six years by collecting them on his daily walks, crushing them and passing them to his owner.

I recall reading the Guinness Book of World Records in the newspaper comic section in the early sixties.

I’ve been a fan ever since.
