The German tourists on the bus laugh as the pack of feral dogs crosses the street at the airport roundabout. And why should they not? There are three dirty Jack Russell terrier and one lanky greyish-brown greyhound, an odd-looking combination for a modern day pack of hounds. The tourists do not know that the dogs hunt hares in the bushes and undergrowth around the business parks in Dublin 15, tearing them to pieces. The dogs leave shreds of paws and ears and bits of bone lying around the car parks for unsuspecting call center workers.
