There is a missing black lab in NW3/NW5 area at the moment (see Doglost UK website for contact details if you see her - her name is Dizzee but don't call her or try to catch her, just follow and ring in to say where you've seen her). She has been spotted on the railway at Kentish Town, outside a pub near Kentish Town Station at about 9 pm at night, on the edge of Hampstead Heath, small bit of heath near Heysham Lane area (wherever that is).

Hoping very much she gets recaptured before something untoward happens to her, poor thing.
