Radioactive dogs of Chernobyl

I've visited the Chernobyl zone three times now, and each time there are apparently stray dogs roaming around.  Most of them look reasonably healthy, so one has to assume someone is feeding them.  As you may know I have a soft spot for dogs, more so after the passing of Skip very recently.

Some are very timid, and you can't get close to them.

I've seen them in all parts of the zone, from Chernobyl town, 10 km away from the power station, to the building site, just a hundred metres or so away from the reactor that went boom.

I'd have loved to have taken one of the pups we found home on the most recent trip home with me.

NB.  One of these is not a dog!
