Bertie the litter picking dog

Bertie is a Welsh Springer Spaniel who is known for his environmental exploits. Bertie enjoys collecting plastic bottles whilst out on walks with his owner, Martyn, and since he first started on his eco mission, he has rescued more than 10,000 plastic bottles from the local parks and countryside across Coventry and Warwickshire.

BBC CWR's Vic Minett has been speaking to Martyn Brunt about what makes Bertie such a good boy.
