Well that was strange.
Yesterday evening a group of lads appeared on the doorstep. With them was an elderly black male greyhound, they had apparently found it and borrowed a lead from a local dog owner. They knew that we had greys and thought that we would know what to do with it.
Of course there was no tag on the collar so I took it to the local vet and left my details, they will be in touch later today if the old boy is chipped, if not or the owner doesn't want him we may well keep him, or see if a friend who always has elderly greys would like him.
I have spoken to the local dog warden and he seems happy with the plan.
