It is a 2nd century AD Roman copy of a Hellenistic bronze original, and is 1.05 metres high. Although it is one of only a small number of animal sculptures surviving from antiquity, a pair of similar marble mastiffs of the same model can be seen in the Belvedere Court of the Vatican MuseumsThe breed has been identified by the British Museum as a Molossian guard dog. This breed was native to Epirus in north-western Greece, which was sacked by Rome in 168 BC, so it is assumed to have been associated with some civic monument in Epirus and to have been brought to Rome after the sacking. Pliny mentions a highly valued bronze dog surviving in Rome into his lifetime, before being lost in 69 AD"
