I had heard that about Oxfordshire Sue. Oxford Centre has a high percentage. The last time I was at the Iffley Rd vet which is close to Oxford City Centre, there was a lady in there with a staffy. She told me she had just got him back after he was stollen on a walk in University Parks 2 months previously. She saw him being taken and put into a car and thinks that he must have escaped as he was found walking the streets. His collar was gone but he was chipped and they were able to contact her (which just goes to prove that chipping is still important). She had tears in her eyes when she was telling me, so obvioulsy overjoyed to have him back.
My mum is always worried as whippets are high priority for racing.
