It is the Welsh Sow.
The earliest references to a Welsh pig comes from the 1870's, when there was a considerable trade in Welsh and Shropshire pigs into Cheshire, for fattening on milk by-products.
The Welsh pigs(heard that cry before somewhere) are generally a yellow-white but some are spotted black and white.
They are still known for their hardiness and ability to thrive under a wide variety of conditions, both indoor and outside.
Did I mention these are all Pedigree Pigs?
This next one reminds me of Amos Brearley, what do you think?
