We visited an animal rescue centre today quite close to Biggin Hill Airport, and spent some time with 2 ex racing greyhounds. The first was very nervous and not ready yet for re-homing - the very helpful keeper thought he had been hit by its racing owner, but the second, which had already been reserved, demonstrated that this would be the right type of dog to have in our home. Oddly enough they don't need much more than two 30 minute walks every day, and are generally very quiet and affectionate.
