There is a publication called The Complete Pembroke Welsh Corgi. My guy's lineage is all through the book. I brought him home at seven weeks and he lived almost 15 years, about 1/4 as long as i would have preferred. His son from his third litter we took as stud fee and he too lived nearly 15 years. For over 20 years we had corgis letting us serve them in this house. It has been long enough since we lost the last one that my wife is on-line slobbering over puppies.
By far the coolest, smartest dogs I've ever had.
