WimbledonAndy Murray goes to the dogs, or more precisely the puppies, in a video released on Tuesday which shows him playing at Wimbledon with five cocker spaniels being trained to become sniffer dogs. The six-week-old puppies are being raised by the Metropolitan Police Service and Murray, a self-professed dog lover and a World Wildlife Fund global ambassador, supports the use of sniffer dogs to crack down on wildlife poaching in Nepal, a release from the Wimbledon press office says. In the video (http://bit.ly/1LVv8dr) Murray is shown playing with the puppies on the famous hill within Wimbledon's grounds while they run around him and chew on his shoelaces and fingers.
