I was sent this and thought I should share it, it sounds like someone was using a squeaker to call a dog to them and take it...
At 9.30pm on Monday 1 August 2011 a Reading resident was exercising her female Lurcher in Christchurch Meadow, Caversham, Reading near the river Thames. A male person was seen sitting on a bench with a rucksack nearby. The owner said the man was continuously whistling to get the dog's attention but the sound was unusual like someone using their teeth/tongue or a piece of thin plastic to make the noise. The dog went over to the man who got up, moved towards her,
