Well, he is mine (or rather, my wife's). He is actually a rather nice dog; I will send you a photo to your private mail, if I find it. I guess that he has a bit of most races (although some say he is substantially a Portuguese podenco)!
Actually, we were just supposed to keep him for a week or so. He had been abandoned (like a lot of dogs here in Spain), had spent almost a year in the cages of some kind of public dog kennel where he was just given enough food to survive (he was in a lousy state whe he got out, the feet burnt by the stuff they use to clean the floors of the cages, the fur in a horrible state, the tail broken at several places; he has also a bed leg and a blind eye -the one you see in the photo is the one he sees with!-). An association for help to animals got him out of the kennel just before they were supposed to sacrifice him, and we were supposed to have him until someone adopted him. Now, he is such a nice dog that we have kept him (and another one that arrived later).
He may be a silly avatar for this forum, but I guess that I felt that his "scruffy" style could be a nice contrast to all the elegance that impregnates this forum (something like the fly that the painter used to add to a nice Stilleben).
