Topaz the Leonberger with a Christmas tree and cart
A team of large Leonberger dogs will be at Hinchingbrooke Park on 9 January 2011 to help recycle Christmas trees.
The working dogs will use carts and harnesses to carry the trees from people's cars to the chipping machines.
John Tyler is chair of the working dogs section of the Leonberger Club of Great Britain.
He said: "The recycling is free but we hope people will donate to Hounds for Heroes. It's a way to thank our troops and these dogs for their work."
John's Tyler's own Leonbergers, Amber and Topaz, will take part in the event, with other Leonberger enthusiasts bringing their dogs from across East Anglia and the Midlands.
The large German breed excels at water work, carting, obedience, working trials and agility exercises, and Mr Tyler describes them as dogs "with both brains and brawn".

This year's recycling event takes place in the car park at Hinchingbrooke Country Park, near Huntingdon, on Sunday, January 9 2011 between 10.30am and 3pm.
Bring your own bag and you will be able to take chippings home to use on your garden, otherwise they will be used in the park.
Any donations made will go toward the charity Hounds for Heroes, which provides specially-trained assistance dogs to injured and disabled men and women of both the UK armed forces and civilian emergency services.
