@mawr Inbreeding? O:)
(But in Jack and Toast's case, the cutest and best inbreeding! Corgis are the best of both worlds, brave little dogs that act big! And I get the impression that except for some minor hereditable eye problems, corgis have pretty hale and healthy genetics for purebreds...)
@zebratron2084 And both Jack and Toast are a mix of pembroke and cardigan so they're even better off. :D
